This study compares the way IVET and CVET sub-systems interact to support the learning of adults, and thus facilitate lifelong and life-wide learning. By comparing the interaction between IVET and CVET sub-systems in the countries covered, the study analyses the extent to which IVET systems are opening up to adults, and questions whether national and regional policies and practices support or prevent a closer link between CVET and IVET. The study builds on concrete national case-studies, allowing for an in-depth, qualitative comparison and analysis of practices and policies. This allows for a better understanding of obstacles and opportunities in this complex area, directly supporting the stakeholders and policy-makers responsible for taking lifelong and life-wide learning in Europe forward.

This report presents a holistic approach to understanding and comparing vocational education and training (VET) systems. The approach has been developed jointly by a group of interdisciplinary VET researchers over a 5-year period as part of Cedefop's research on the future of VET and has been reviewed several times. The framework introduces 50 dimensions for analysing VET systems, as well as parts of them, structured according to three overlapping main perspectives: epistemological and pedagogical, education system, and socioeconomic or labour market. The framework is particularly suited to 'clearing the ground' for policy work and provides a model for how research can support policy. This model can be flexibly adapted and applied in any comparative research or international policy learning activity related to VET.

Intersectionality highlights that different aspects of individuals' identities are not independent of each other. Instead, they interact to create unique identities and experiences, which cannot be understood by analysing each identity dimension separately or in isolation from their social and historical contexts. Intersectional approaches in this way question the common classification of individuals into groups (male vs. female, immigrant vs. native etc.), which raises important implications for the policy-making process. In education, analyses with an intersectional lens have the potential to lead to better tailored and more effective policies and interventions related to participation, learning outcomes, students' attitudes towards the future, identification of needs, and socio-emotional well-being. Consequently, as elaborated in this paper, some countries have adjusted their policies in the areas of governance, resourcing, developing capacity, promoting school-level interventions and monitoring, to account for intersectionality. Gaps and challenges related to intersectional approaches are also highlighted.

Calls for increased monitoring and evaluation of education policies and practices have not, so far, included widespread and consistent assessments of the inclusiveness of education settings. Measuring inclusion in education has proven to be a challenging exercise, due not only to the complexity and different uses of the concept, but also to its holistic nature. Indeed, measuring inclusion implies analysing a variety of policy areas within education systems, while also considering the different roles of the system, the school and the classroom. This paper discusses the application of the input-process-outcome model to the measurement of inclusion in education, and key indicators that can be adopted by education systems and schools to this end. It makes considerations relevant to policy makers when designing indicators to measure inclusion, such as the extent of their application, the constraints related to data disaggregation and the relevance of intersectional approaches to inclusion.

Co-constructing a long-term sustainable vision on the future of teaching is a policy priority for many countries as society rapidly changes. There is a need to create space in the teacher debate to look forward for inspiration and to learn from contemporary change in other professions, such as the concept of "connective professionalism". There is also a paradox to navigate. On the one hand, the idea of change can be daunting. This leads to people seeking comfort in the known. On the other hand, the status quo is unlikely to provide the solutions required for a prosperous and sustainable future for the teaching profession. In this paper, we introduce an Ambition loops tool to create preferred future scenarios that can support the work of teachers, add to the prosperity for students and communities, and support transformation of education to meet contemporary challenges while focusing on current needs. The framework has an iterative design and outlines ambitions relevant to all stakeholders in the school-community, education community and broader societal sectors. The current framework statements have been distilled from a review of the research as well as engagement with experts and practitioners.

Principals (policy makers) have debated the progress in U.S. student performance for a half century or more. Informing these conversations, survey agents have administered seven million psychometrically linked tests in math and reading in 160 waves to national probability samples of selected cohorts born between 1954 and 2007. This study is the first to assess consistency of results by agency. We find results vary by agent, but consistent with Flynn effects, gains are larger in math than reading, except for the most recent period. Non-whites progress at a faster pace. Socio-economically disadvantaged white, black, and Hispanic students make greater progress when tested in elementary school, but that advantage attenuates and reverses itself as students age. We discuss potential moderators.

The feedback between vocational education and training (VET) and the labour market can provide important input for the review and renewal of qualifications. A feedback loop that is based on learning outcomes helps provide deeper insights into what is required on the labour market, what is offered in training provisions and assessed at the end of a learning programme. The aim of this study is to contribute to strengthening the quality and relevance of qualifications and completing the feedback loop between education and the labour market. It examines methods of collecting data on the match/mismatch between qualifications and labour market requirements, including analysis of how achieved learning outcomes are applied and perceived in the labour market (for example methods of collecting the experience of employers with holders of these qualifications). This report addresses the following two questions: (1) which data already exist in the countries, providing insight into the relevance of qualifications to employees, employers and other labour market stakeholders?; and (2) how can survey methodology be designed to systematically capture the experiences and appreciations of employers as regards the content and profile of qualifications? To what extent, based on limited testing, can scalability of the methodology be achieved?

The European Union is likely the most far-developed cross-border public space for higher education. The European Higher Education Area (EHEA) and the European Research Area (ERA) both span an even larger number of countries including associate and partner countries of the EU. Based on shared European values, such as academic freedom, cross-border cooperation, and mobility, these policy frameworks have been developed in Europe over the last decades and with much success. HE systems in this area are thus well-positioned to benefit from cross-border mobility and collaboration but may at the same time face a certain loss of control over HE, for instance with respect to access due to the cross-border flows of students. This seems to make them vulnerable to populist tendencies and neo-nationalist politics seeking to inhibit the free movement of students, scholars, and data. Such tendencies have never been completely absent on the "old continent" but resurged over the uneven outcomes of globalization, the effects of the global financial and consequent Euro crisis, and the refugee crisis. Meanwhile, the impact of the coronavirus crisis is still by and large unknown. Populist tendencies seem now to be turning against the EU, with its freedom of movement for persons (i.e. open borders) as one of its cornerstones and are therefore of concern for the HE sector. Countries such as the UK, Switzerland, Denmark, and the Netherlands have a different position in the European landscape but are all struggling with the complexity of combining the virtues of an open system with constrained national sovereignty. Sovereignty is required in terms of steering capacity in order to balance access, cost, and quality, i.e. the well-known "higher education trilemma." In open systems this is challenged by the "globalization trilemma", which states that countries cannot have national sovereignty, (hyper)globalization and democracy at the same time. How are the EU, its Member States, and the HE sector responding? Will the Union stay united (i.e. Brexit)? Are the legal competencies of the EU in HE strong enough? What about the many European university associations, leagues, and networks? And what do the millions of (former) Erasmus students have to say?

Higher education institutions (HEIs) are more critical than ever to help societies respond to the complex challenges of our times. Recognising that these challenges require HEIs to adopt holistic innovations in teaching, research and collaboration activities, the European Commission (EC) and the OECD have developed the HEInnovate guiding framework. HEInnovate promotes innovation and entrepreneurship in higher education and provides guidance to policy makers and HEIs that want to generate additional societal and economic value. This policy brief distils the main findings and recommendations of 13 HEInnovate Country Reviews that have examined higher education system and institution, identifying factors affecting the delivery of the entrepreneurial and innovation agenda in higher education. Looked at in the round, the country reviews provide HE leaders with peer-learning and best practices, policy makers with tested policy solutions and the European Union and the OECD with a deeper understanding of the state of innovation and entrepreneurship in higher education.

Education is one of the most important fields to promote the integration of refugee and newcomer children and youths in host countries. However, holistic education for refugee and newcomers has so far not been established into mainstream education systems in European countries. Projects and pilot programmes have developed across Europe to test holistic approaches. Some of them have started very recently as a response to the arrival of high numbers of refugees and newcomers, while others have been established for a longer period and have started to expand. This paper first provides an overview of key research gaps in refugee education. It then provides a mapping of promising holistic education practices in Europe, with a focus on Germany, Greece and the Netherlands. Based on this, the paper explores key conditions to upscale and institutionalise promising practices of holistic refugee and newcomer education.

Validation and guidance help individuals, organisations and Member States adapt to career challenges and create successful lifelong learning systems. However, little is known about how they are linked in practice and how this connection can be made more efficient. Building on Cedefop's expertise in the two areas, this study -- based on analysis of 13 practices from 12 countries -- explores how coordination between career guidance and validation of non-formal and informal learning can be improved. Results point to three factors: (a) comprehensiveness: provision of adequate information and guidance before a decision to undergo validation is taken, throughout the entire validation process, as well as after it; (b) coherence: use of common qualifications or competence standards, occupational standards or other reference frameworks in all the stages of the practice to identify, document and assess skills; and (c) quality of staff, resources, competences, and tools used. The study concludes with policy recommendations on how to improve the link between guidance and validation.

Across OECD countries, the increasing demand for evidence-based policy making has further led governments to design policies jointly with clear measurable objectives, and to define relevant indicators to monitor their achievement. This paper discusses the importance of such indicators in supporting the implementation of education policies. Building on the OECD education policy implementation framework, the paper reviews the role of indicators along each of the dimensions of the framework, namely smart policy design, inclusive stakeholder engagement, and conducive environment. It draws some lessons to improve the contribution of indicators to the implementation of education policies, while taking into account some of their perennial challenges pertaining to the unintended effects of accountability. This paper aims to provide insights to policy makers and various education stakeholders, to initiate a discussion on the use and misuse of indicators in education, and to guide future actions towards a better contribution of indicators to education policy implementation.

This research paper is the fifth in a series produced as part of the Cedefop project The changing nature and role of VET (2016-18). Based on comparative analysis of labour force survey data from 2014, the report analyses the vocational effect on labour market and education outcomes, asking whether any advantages conferred by vocational qualifications in early career would be offset by disadvantages later in life. The report explores the functioning of the safety net and the diversion effects across countries, demonstrating how these vary considerably with the specific institutional structure of schooling and work-based training. The results indicate that VET graduates are potentially sacrificing the longer-term gains associated with further education in favour of short-term benefits.

In a highly competitive global landscape, occupations are transformed, new jobs are created and the skills needed for the labour market are constantly changing. European countries are looking at redefining VET [vocational education and training] to respond promptly to such challenges and take advantage of the opportunities ahead. They are reforming to modernise their VET systems and strengthen the relevance of their national qualifications in an international context. This publication explores national responses to globalisation in 15 countries and five economic sectors. It aims to understand how European and international initiatives help VET renewal across Europe. It shows how countries' reactions are embedded in their national traditions but also depend on their interactions with European, sectoral and multinational players that provide training and award qualifications.

Governments recognise that careers guidance, underpinned by accurate labour market information, can help learners make post-secondary education choices that match their interests, aptitudes and abilities, and lead to rewarding employment. For this reason, they have invested in building linked education/employment information systems and other information resources which are displayed on websites targeted to learners and their families. However, researchers and governments agree that these efforts are often ineffective in informing learners' decisions -- access to information is not sufficient to provide effective support to student choice. Drawing upon the insights of behavioural economics, this paper examines how learners access and use information, and what this implies for the design of public study and career choice websites that aim to effectively support student choice. The report also takes stock of the career guidance websites in use in the majority of OECD countries, and sets out to provide actionable advice for policy makers to guide the design of effective information policy levers that support student choice.

The paper investigates two -- often disconnected -- policy questions: how can we scale the use of evidence in teaching practice, and how can we generate and scale innovation? Both questions necessitate understanding how teachers and schools connect with each other, and with other organisations and professionals. The paper thus explores the role of networks in scaling evidence and innovation through a review of literature and a number of short case descriptions. Through the lens of networks, the analysis shows how the mobilisation, construction and diffusion of knowledge are of central importance in both policy issues. It suggests that scaling evidence and innovation should be treated as one ecosystem, in which mechanisms that allow effectively blending research and practical knowledge are key. Further, the paper proposes a framework for studying knowledge dynamics in networks to better understand how their context, characteristics and devices can contribute to facilitate these dynamics.

This research paper has the objective of providing a comprehensive overview of Dutch education policy approaches to the integration of children with a migration background, with a particular focus on those who have recently arrived in the country. After mapping the current population characteristics of children with a migration background and their educational performance and socio-emotional well-being, the research paper summarises the Dutch education system and the opportunities it provides for newcomer children. The remainder of the paper focuses on three key policy issues that are crucial for promoting the academic and social resilience of children with a migration background: promoting social cohesion and multiculturalism in schools, capacity building in the education system and language acquisition for newcomers. The paper concludes with pointers for the short and long-term policy debates to enhance the successful integration of students with a migration background in the education system as well as the wider society.

The worldwide school closures in early 2020 led to losses in learning that will not easily be made up for even if schools quickly return to their prior performance levels. These losses will have lasting economic impacts both on the affected students and on each nation unless they are effectively remediated. While the precise learning losses are not yet known, existing research suggests that the students in grades 1-12 affected by the closures might expect some 3 percent lower income over their entire lifetimes. For nations, the lower long-term growth related to such losses might yield an average of 1.5 percent lower annual GDP for the remainder of the century. These economic losses would grow if schools are unable to re-start quickly. The economic losses will be more deeply felt by disadvantaged students. All indications are that students whose families are less able to support out-of-school learning will face larger learning losses than their more advantaged peers, which in turn will translate into deeper losses of lifetime earnings. The present value of the economic losses to nations reach huge proportions. Just returning schools to where they were in 2019 will not avoid such losses. Only making them better can. While a variety of approaches might be attempted, existing research indicates that close attention to the modified re-opening of schools offers strategies that could ameliorate the losses. Specifically, with the expected increase in video-based instruction, matching the skills of the teaching force to the new range of tasks and activities could quickly move schools to heightened performance. Additionally, because the prior disruptions are likely to increase the variations in learning levels within individual classrooms, pivoting to more individualised instruction could leave all students better off as schools resume. As schools move to re-establish their programmes even as the pandemic continues, it is natural to focus considerable attention on the mechanics and logistics of safe re-opening. But the long-term economic impacts also require serious attention, because the losses already suffered demand more than the best of currently considered re-opening approaches.

This paper investigates how legal cannabis access affects student performance. Identification comes from an exceptional policy introduced in the city of Maastricht which discriminated legal access based on individuals' nationality. We apply a difference-in-difference approach using administrative panel data on over 54,000 course grades of local students enrolled at Maastricht University before and during the partial cannabis prohibition. We find that the academic performance of students who are no longer legally permitted to buy cannabis increases substantially. Grade improvements are driven by younger students, and the effects are stronger for women and low performers. In line with how THC consumption affects cognitive functioning, we find that performance gains are larger for courses that require more numerical/mathematical skills. We investigate the underlying channels using students' course evaluations and present suggestive evidence that performance gains are driven by improved understanding of material rather than changes in students' study effort.

Are teachers and principals aligned in their perceptions of the core components of the theory of Leadership for Learning across countries, or are there subgroups of schools in which there is misalignment? The purpose of this study is to examine the extent to which a congruency-typology model of leadership for learning is distributed across countries/economies using the TALIS 2018 dataset through examining the interaction of significantly different subgroups of teacher and principal responders through using multilevel latent class analysis (LCA) with a cross-level interaction. I analyse data from lower secondary schools of n=152 635 teachers in 9 079 schools and their principals across 47 countries/economies. Currently in the research literature on school leadership, leadership for learning has emerged as a framework to bring together managerial, transformational, distributed, and instructional leadership. Yet little is known about leadership for learning across national contexts. This study 1) maps the TALIS 2018 survey items to the current literature and surveys for leadership for learning, 2) then details the methods and analysis framework to examine if there are multiple significantly different types of teachers, principals, and schools from a leadership for learning theory framework. The final model 3) identifies a three-group teacher typology and a three-group principal typology, linking these types to school context, covariates, as well as teacher and principal training and experience. Results relate directly to the intersection of research, policy, and practice for training and capacity of school leaders across 47 countries/economies globally.

This systematic review investigates the relevance of general pedagogical knowledge for successful teaching. It synthesises the empirical evidence of 10 769 teaching professionals and 853 452 students from primary to tertiary education in 21 countries. The meta-analysis of 20 quantitative studies revealed significant effects for teaching quality and student outcomes (Cohen's d = 0.64 and 0.26), indicating that more knowledgeable teachers achieve a three-month additional progress for students. The three themes emerging from 31 qualitative studies underline that general pedagogical knowledge is a crucial resource for teaching. Results also show that teaching requires knowledge about a range of topics, specific skills and other competences to transform knowledge into practice. Teachers need training and practical experience to acquire knowledge, which they apply according to the pedagogical situation at hand. The results allow for important conclusions for policy, practice and research.

The recent refugee crisis has put many Organisation for Economic Cooperation and Development (OECD) countries under considerable pressure to accommodate and integrate large numbers of refugees. Refugee students are a particularly vulnerable group due to their forced displacement, but their needs are not always met by education systems, which can hinder the integration potential of these students. This poses considerable challenges as the integration of refugee students in education systems is important for their academic outcomes as well as their social and emotional well-being. The success (or lack of) integration in schools can also affect the future labour market and social integration potential of these children and youth. While there is a growing body of research on the integration of immigrants, policy-relevant research on refugee children and youth from an educational perspective is rather limited, fragmented and case specific. Detailed surveys and research projects focusing on the current wave of refugees that allow for cross-country comparisons are not yet available. Drawing on research from previous refugee waves, the paper examines key needs of refugee students and factors that promote their integration. It proposes a holistic model of integration in education that responds to the learning, social and emotional needs of refugee students. Furthermore, the paper examines what type of policies and practices are in place in OECD countries that support the integration of refugee students. Nonetheless, evaluations of practices and policies are often missing, which makes it difficult to assess whether they are successful. The paper finishes with some policy pointers on how to promote the integration of refugee students.

This paper explores the impact of test-taking conditions on the quality of the Programme for the International Assessment of Adult Competencies (PIAAC) assessment. Interviewers record information about the room of assessment and interruptions that occurred during each interview. These observations, along with information on interviewer assignment size and a careful look at interviewer effects, provide insights into the quality of the assessment. This working paper first describes the variations in test-taking conditions among participating countries. Second, it examines interviewer assignment sizes and the frequency of interruptions, finding that both vary markedly among countries (contrary to the room of assessment). The paper then looks at the relationship between these variations and response rates and engagement measures. While neither the room of assessment nor the recorded interruptions impact quality differences among countries, interviewer assignment size and interviewer effects may have a mild impact on results.

Prepared for a Strategic Education Governance learning seminar, this working paper analyses the ways in which the Dutch government tried to reach overarching goals in education, in a system characterised by a high degree of distributed autonomy of education institutions and the participation of multiple actors, and consequently a government highly dependent on the collaboration with stakeholders. The paper introduces four perspectives on governance: 'traditional public administration', 'new public management', 'network governance' and 'societal resilience'. In practice, these perspectives do not exclude each other. Based on three cases the paper shows that the Dutch government used simultaneously different perspectives in each case and across the cases, in various combinations. Each combination proved to have its pros and cons. The paper argues for a deliberate consideration and choice of governance perspectives as an important element of policy preparation.

This paper looks at the importance of mechanisms that give formal recognition to vocational skills acquired through work-based learning and how such mechanisms might be developed. It describes how skill recognition can benefit individuals, employers and society as a whole, and identifies in which contexts skill recognition has the highest potential to bring benefits. The focus is on three tools that are commonly used to shorten the path to a formal qualification: admission into a programme, reduced programme duration and qualification without a mandatory programme. For each of these tools, this paper sets out country approaches, discusses common challenges that arise in their implementation and advances policy messages to support policy design and implementation.

The opportunity to study abroad is broadly hailed as a route for young people to develop a wide range of knowledge and skills, including intercultural understanding, interpersonal skills, and language learning, among many others. Universities around the world are investing significant resources in developing a variety of study abroad programmes, ranging from short or long term in duration, and from guided to independent study. These may have a number of aims, including to promote individual student learning and development and to enhance student mobility and employability, particularly in the context of a rapid and changeable global employment market. The terms 'global citizen', 'global graduate', 'global skills' and 'global mindset' have all taken on increased significance within this context. Limited research has been conducted, however, to explore students' own perspectives of these terms. This small scale study therefore set out to explore the perspectives of students on UCL's BASc programme and especially to better understand where and how the learning they gained during study abroad resonates with UCL's global citizenship and student mobility strategies.

Numeracy and literacy skills have become increasingly important in modern labour markets. The large gender differences that several studies have identified have therefore sparked considerable attention among researchers and policy makers. Little is known about the moment in which such gaps emerge, how they evolve and if their evolution differs across countries. We use data from large-scale international assessments to follow representative samples of birth-cohorts over time, and analyse how gender gaps in numeracy and literacy evolve from age 10 to age 27. Our results suggest that, across the countries examined, males' advantage in numeracy is smallest at age 10 and largest at age 27. The growth in magnitude of the gender gap is particularly pronounced between the age of 15 and 27. Such evolution stands in sharp contrast with the evolution of the gender gap in literacy, which is small at age 10, large and in favour of females at age 15, and negligible by age 27.

This study uses the PIAAC data to examine the relationships between education system characteristics (e.g. early tracking and vocational education orientation) and distributions of adult numeracy skills. It also investigates the effects of postponing the tracking age and easing university access for students on a vocational track on the average skills and different percentiles of the skills distribution. Correlational analysis suggests that education systems with more students enrolled in vocational tracks have on average higher levels of numeracy skills and more compressed skills distributions between the 50th and 90th percentiles. Further analysis suggests that postponing the tracking age among 14 European countries does not have a significant effect on the average skills of the population. However, it increases skills for individuals at the 10th, 20th, and 30th percentiles of the skill distribution. Expanding university access is associated with an increase in numeracy skills, particularly for individuals at the bottom three deciles of the distribution.

It is well-known that there are large disparities in academic achievement between children of different socio-economic status (SES) backgrounds. This study examines the evolution of disparities in literacy skills between adults of different SES backgrounds. It compares countries' patterns in the evolution of disparities in literacy by SES background as cohorts age and asks which patterns of educational and labour force participation predict a narrowing rather than a widening of these disparities. Since there is no international longitudinal study of skills across the entire adult life span, this study uses three cross-sectional international adult studies (International Adult Literacy Survey, Adult Literacy and Lifeskills and Programme for the International Assessment of Adult Competencies) and matches birth years to create synthetic cohorts. Results indicate that there is large cross-national variation in the evolution of skills disparities associated with SES background. Disparities in literacy proficiency tend to widen when SES disparities in high school completion, professional and blue-collar employment increase. Disparities narrow when workers exit the labour force, a finding that is explained by the large inequalities in the employment experiences of individuals from different SES backgrounds, measured by differences in use of literacy skills at work. These results help to explain cross-national variation in the evolution of skills disparities by SES background, which has implications for policies aimed at closing skills gaps over the life course.

Resilience refers to the capacity of individuals to prosper despite encountering adverse circumstances. This paper defines academic resilience as the ability of 15-year-old students from disadvantaged backgrounds to perform at a certain level in the Programme for International Student Assessment (PISA) in reading, mathematics and science that enables them to play an active role in their communities and prepares them to make the most of lifelong-learning opportunities. Using data from the most recent PISA cycles, this paper explores changes in the share of resilient students over time (2006-2015); highlights the importance of school environments and resources in mitigating the risk of low achievement for disadvantaged students; and identifies school-level factors that are associated with the likelihood of academic resilience among socio-economically disadvantaged students. Analyses reveal that several countries were able to increase the share of resilient students over time, reflecting improvements in the average performance of students, or a weaker relationship between socio-economic status and performance. In the vast majority of education systems examined, the likelihood of academic resilience among disadvantaged students is lower in schools where students report a negative classroom climate. The paper concludes by exploring school policies and practices that are associated with a positive classroom climate.

The paper examines between-country differences in the mechanisms through which education could promote generalised trust using data from 29 countries participating in the OECD's Survey of Adult Skills (PIAAC). Results indicate that education is strongly associated with generalised trust and that a large part of this association is mediated by individuals' literacy skills, income and occupational prestige. However, education gradients in levels of generalised trust and in the extent to which they are due to social stratification mechanisms or cognitive skills mechanisms vary across countries. Differences across countries in birthplace diversity and income inequality are correlated with how strongly education is associated with trust in different countries, as well as in the relative magnitude of direct and indirect associations. In particular, the relationship between literacy skills and generalised trust is stronger in the presence of greater birthplace diversity but is weaker in the presence of greater income inequality.

We assess the relationship between general literacy skills and health status by analysing data from the Programme for the International Assessment of Adult Competencies (PIAAC), an international survey of about 250,000 adults aged 16-65 years conducted by the Organisation for Economic Co-operation and Development (OECD) from 2011-15 in 33 countries/national sub-regions. Across countries, there seems to be a strong and consistent association between general literacy proficiency and self-rated poor health, independent of prior socio-economic status and income. General literacy proficiency also appears to be a mediator of the association between self-education and self-rated poor health. While the literacy-health association is robust over time, it varies in magnitude across countries. It is strongest for those with a tertiary or higher degree and does not appear to exist among young adults (ages 25 to 34 years). Future studies are required to understand the contextual factors that modify the general literacy proficiency-health association.

This paper presents a comprehensive analysis of the link between age and proficiency in information-processing skills, based on information drawn from the Survey of Adult Skills (PIAAC). The data reveal significant age-related differences in proficiencies, strongly suggesting that proficiency tends to "naturally" decline with age. Age differences in proficiency are, at first sight, substantial. On average across the OECD countries participating in PIAAC, adults aged 55 to 65 score some 30 points less than adults aged 25 to 34 on the PIAAC literacy scale, which is only slightly smaller than the score point difference between tertiary educated and less-than-upper-secondary educated individuals. However, despite their lower levels of proficiency, older individuals do not seem to suffer in terms of labour market outcomes. In particular, they generally earn higher wages, and much of the available empirical evidence suggests that they are not less productive than younger workers. Older and more experienced individuals seem therefore able to compensate the decline in information processing skills with the development of other skills, generally much more difficult to measure. On the other hand, proficiency in information-processing skills remain a strong determinant of important outcomes at all ages: this makes it important to better understand which factors are the most effective in preventing such age-related decline in proficiency, which does not occur to the same extent in all countries and for all individuals. Two broad interventions seem to be particularly promising in this respect. First, it is important to ensure that there is adequate and effective investment in skills development early in the life-cycle: as skills beget skills, starting off with a higher stock of human capital seems also to ensure smaller rates of proficiency decline. Second, it is equally important that policies are in place that provide incentives to individuals (and firms) to invest in skills across the entire working life. In this respect, changes in retirement policies can not only have the short-term effect of providing some reliefs to public finance, but have the potential to radically reshape incentives to stay active, to practice their skills and to invest more in training, thus helping to maintain high levels of proficiency. One table, Age Differences and Age Effects, is appended.

Realising the potential of work-based learning schemes as a driver of productivity requires careful design and support. The length of work-based learning schemes should be adapted to the profile of productivity gains. A scheme that is too long for a given skill set might be unattractive for learners and waste public resources, but a scheme that is too short will fail to attract employer interest. Ensuring that the design of work-based learning schemes balances the interests of both employer and trainee is key to successful implementation. Carefully organising what trainees do while in the workplace and integrating learning into productive work can yield higher benefits for firms, while maintaining the quality of learning. Strengthening capacity within firms to effectively manage work-based learning can help achieve this. Enhancing that capacity, for example through training for trainee supervisors can help employers reap more benefits from work-based learning schemes while meeting quality requirements. Two tables are appended.

Using the 2012 PIAAC data, our analysis confirms that there are significantly higher earnings and employment returns to "both" increasing levels of formally recognised education, and to increasing levels of numeracy, literacy and information and communication technologies (ICT) skills proficiencies controlling for the level of education. Unsurprisingly, the labour market returns to changes in formally recognised levels of education in general exceed the labour market returns associated with increasing levels of skills proficiency. In the case of literacy and numeracy proficiencies, improved literacy and numeracy skills narrow the labour market outcomes gap between individuals with different levels of formally recognised education, but do not close it completely. The analysis demonstrates more substantial returns to ICT skills. Furthermore, possession of higher levels of ICT skills and lower levels of formally recognised qualification are often associated with higher returns compared to individuals with higher levels of formally recognised education but lower ICT proficiency levels.
