We study whether autonomous schools, which are publicly funded but can operate more independently than government-run schools, affect student achievement and school segregation across 15 countries over 16 years. Our triple-differences regressions exploit between-grade variation in the share of students attending autonomous schools within a given country and year. While autonomous schools do not affect overall achievement, effects are positive for high-socioeconomic status students and negative for immigrants. Impacts on segregation mirror these findings, with evidence of increased segregation by socioeconomic and immigrant status. Rather than creating "a rising tide that lifts all boats," autonomous schools increase inequality

This report describes how entrepreneurship competence is embedded in vocational education and training (VET) in Finland. It complements existing knowledge with examples of methods, tools and approaches that can help policy-makers, VET providers and other stakeholders build better entrepreneurial learning ecosystems. The report is based on the research of the Cedefop study "Entrepreneurship competence in VET." It is part of a series of eight national case studies (Spain, France, Croatia, Italy, Latvia, Austria, Sweden and Finland) and a final report.

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.

This report summarises the findings of the 2022 EUA Thematic Peer Group which explored collaborative teaching practice (CTP) in higher education in detail. Based on a shared understanding of the theme agreed on by the group members, it outlines the key opportunities and potential challenges higher education institutions face in embedding CTP and provides examples of practice from the group members. Given the many inter-institutional, national and international collaborations developed during the pandemic, the group regarded the use of digital technologies as a key feature of collaborative teaching, and it therefore became a key focus of their discussions. The report identifies the various ways in which the group's members collaborate as part of their learning and teaching activities, highlights the key challenges that higher education institutions face in implementing collaborative teaching and suggests a set of recommendations for individuals, institutions and national and European-level bodies to overcome those challenges identified. The group was organised in the context of the "Supporting European universities in their strategic approaches to digital learning" (DIGI-HE) project and EUA's Learning & Teaching activities.

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?

Individual teachers, administrators, and parents made tremendous efforts to continue educating the Commonwealth's children between March and June of this year. But no amount of dedicated individual effort could have overcome fundamental challenges: weak guidance to districts from the Department of Elementary and Secondary Education (DESE) against a backdrop of deficient knowledge and sophistication statewide with regard to virtual learning. Digital education has been empirically proven to be most successful when schools prepare and follow best distance learning practices. However, the Commonwealth lacks even the minimum technological infrastructure for virtual learning, as exemplified by districts scrambling to obtain electronic devices and internet connections during the school closure. It is encouraging that Governor Baker and the DESE have described a fall 2020 return to brick-and-mortar schooling--with appropriate health measures to maximize safety--as a significant priority. The present challenge is how to implement this much-needed return to school, optimally balancing the importance of in-person schooling with the countervailing importance of protecting against the virus. The following paper contributes important insights, based upon careful review of other countries that have already successfully reopened their schools. [Foreword written by David S. Clancy and Dr. John G. Flores.]

When does a community create and sustain a truly innovative "next generation" high school that not only remains innovative, but also relevant? According to the Carnegie Corporation, this means seizing the opportunity to redesign schools to promote personalized learning. So far, much work has gone into retooling many of these (reform) elements individually. Many states, districts, and schools have made essential progress in changing teacher preparation and professional development to help talented educators enter and stay in the classroom. There have also been pushes for interventions like additional learning time, new curricula, and new technology, much of which has been shown to have a significant impact on student achievement. However, applied individually, each of these fails to get schools and school systems where they need to be to serve every student. This white paper will explore the issues through the perspectives of several members of the Atlantic Rim Collaboratory, who are attempting to share ideas and concepts on system redesign, by examples of schools that are making deep learning a priority through technology and by examples of initiatives and schools that have made personalized learning and mastery the focus of what they do. All these approaches are important for they become part of a comprehensive whole that can drive meaningful change. [For "Innovation and Deeper Learning: Model High Schools," see ED604591.]

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.

This paper quantifies the learning gain that accrues to 15-year-old students over one year of schooling in 18 countries and economies, where the cohort eligible to sit the OECD Programme for International Student Assessment (PISA)ISA test overlaps with two distinct school cohorts. School-entry regulations are used as an exogenous source of variation for grade levels in an instrumental- variables framework. The focus on the joint effect of schooling and age, together with (local) linearity assumptions, make it possible to account for differences in school-starting age across students who are expected to be in different grades. On average, students' test scores increase by about one-fifth of a standard deviation over a school year. While estimates of the grade gain for individual countries and economies come with wide confidence intervals, this study also shows the annual learning gain of students around the age of 15 tends to be larger in high-income countries compared to middle-income countries.

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.

The 2020 EUA Learning & Teaching Thematic Peer Group on "Meeting skills and employability demands" explored how universities can ensure that their study programmes reflect the dynamic demands of society and the labour market, and address skills demands throughout the student experience. In this paper, employability is considered as part of universities' mission to educate and to contribute in general to future graduates' personal and professional development, including in lifelong learning. It outlines challenges associated with this mission and provides recommendations to tackle them.

The digital revolution and automation are accelerating changes in the labour market and in workplace skills, changes that are further affected by fluctuations in international and regional economic cycles and employment opportunity. These factors pose a universal policy challenge for all advanced economies and governments. In the workplace, people seek to acquire contemporary and relevant skills to gain employment and retain transferable skills to maintain employment. The central purpose of this paper is to investigate how other nations or regions are dealing with these issues. What approaches are they taking to understanding the mix and dynamics of the skills attained by individuals and, more broadly, the totality of skills that in aggregate constitute a highly capable and adaptable labour force, one that supports firm viability and greater national productivity. This research has examined a range of initiatives and approaches being developed or in use in selected countries, including the United States, Singapore and New Zealand, and agencies/organisations; for example, the European Commission and the Skills for the Information Age Foundation. In doing so, it showcases the good practices used to ensure that occupational-level skills information remains current and widely accessible.

Countries consider curriculum reform as an important and necessary measure to make schools enter the 21st century and respond to a fast-changing world. In recent years, many OECD countries have engaged in curriculum reform as a way to equip children with the knowledge, skills and competences needed for tomorrow. However, how to initiate such change in the most suitable and effective way remains somewhat challenging. In other words, there is a missing step between the intention, and the realisation of this curriculum renewal, crystallising what has been coined in the literature "the implementation gap". This paper analyses the curriculum reform literature through the lens of the OECD proposed implementation framework that promotes, among others, inclusive stakeholder engagement. Curriculum reform has indeed long been considered from a "top-down" perspective, but has progressively shifted towards a more "bottom-up" approach, emphasising the central role of teachers in the process. The analysis is enriched with successful practices and examples from different countries, and concludes with a specific resource for countries to make the lessons learned actionable through the planning of a coherent curriculum implementation strategy.

Why is invention strongly positively correlated with parental income not only in the US but also in Finland which displays low income inequality and high social mobility? Using data on 1.45M Finnish individuals and their parents, we find that: (i) the positive association between parental income and off-spring probability of inventing is greatly reduced when controlling for parental education; (ii) instrumenting for the parents having a MSc-degree using distance to nearest university reveals a large causal effect of parental education on offspring probability of inventing; and (iii) the causal effect of parental education has been markedly weakened by the introduction in the early 1970s of a comprehensive schooling reform.

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 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.

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.

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.

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. In other words, ICT skills proficiencies often entirely compensate for lower formally recognised qualifications in the labour market.
