This article bridges the literature on educational inequality between and within families to test whether high--socioeconomic status (SES) families compensate for low cognitive ability in the transition to secondary education in Germany. The German educational system of early-ability tracking (at age 10) represents a stringent setting for the compensatory hypothesis. Overall, previous literature offers inconclusive findings. Previous research between families suffers from the misspecification of parental SES and ability, while most within-family research did not stratify the analysis by SES or the ability distribution. To address these issues, I draw from the TwinLife study to implement a twin fixed-effects design that minimizes unobserved confounding. I report two main findings. First, highly educated families do not compensate for twins' differences in cognitive ability at the bottom of the ability distribution. In the German system of early-ability tracking, advantaged families may have more difficulties to compensate than in countries where educational transitions are less dependent on ability. Second, holding parents' and children's cognitive ability constant, pupils from highly educated families are 27% more likely to attend the academic track. This result implies wastage of academic potential for disadvantaged families, challenging the role of cognitive ability as the leading criterion of merit for liberal theories of equal opportunity. These findings point to the importance of other factors that vary between families with different resources and explain educational success, such as noncognitive abilities, risk aversion to downward mobility, and teachers' bias.

Cognitive and noncognitive skills are key indicators of educational success and merit. However, even when accounting for inequalities in skill formation by family socioeconomic status (SES), a wide SES-gap in college enrolment remains. According to the compensatory advantage hypothesis, SES-gaps in educational transitions are largest among cognitively weak students, but little is known on mechanisms. It has long been argued that noncognitive traits such as effort and motivation might be at least as important as cognitive skills over the status-attainment process, and these skills might interact by being complements or substitutes. Thus, I test whether advantaged students substitute low cognitive skills in test scores by high returns to conscientiousness—rated by teachers— in the transition to academic secondary schools. I draw data from the German National Educational Panel Study to study a cohort of students from Grades 1 to 5, when early tracking is enforced. I estimate linear probability models with school fixed-effects and moderation. To account for measurement error, I also use composite latent skills across elementary education. I report three main findings: (a) High-SES students at the same level of cognitive and noncognitive skills than low-SES schoolmates are more likely to attend the academic track bridged to college; (b) in line with the compensatory hypothesis, these SES-inequalities are largest among low cognitive performers; (3) cognitively weak students from high-SES families get the highest educational returns to conscientiousness in comparison to high cognitive performers or low-SES peers, validating the skill substitution hypothesis. These findings challenge the liberal conception of merit as the sum of ability plus effort in assessing equal opportunity in education. [ABSTRACT FROM AUTHOR]

This study examines the role of genes and environments in predicting educational outcomes. We test the Scarr-Rowe hypothesis, suggesting that enriched environments enable genetic potential to unfold, and the compensatory advantage hypothesis, proposing that low genetic endowments have less impact on education for children from high socioeconomic status (SES) families. We use a pre-registered design with Netherlands Twin Register data (426 ≤ N individuals ≤ 3875). We build polygenic indexes (PGIs) for cognitive and noncognitive skills to predict seven educational outcomes from childhood to adulthood across three designs (between-family, within-family, and trio) accounting for different confounding sources, totalling 42 analyses. Cognitive PGIs, noncognitive PGIs, and parental education positively predict educational outcomes. Providing partial support for the compensatory hypothesis, 39/42 PGI × SES interactions are negative, with 7 reaching statistical significance under Romano-Wolf and 3 under the more conservative Bonferroni multiple testing corrections (p-value < 0.007). In contrast, the Scarr-Rowe hypothesis lacks empirical support, with just 2 non-significant and 1 significant (not surviving Romano-Wolf) positive interactions. Overall, we emphasise the need for future replication studies in larger samples. Our findings demonstrate the value of merging social-stratification and behavioural-genetic theories to better understand the intricate interplay between genetic factors and social contexts. • Genes and family socio-economic status (SES) interact in predicting educational outcomes. • The Scarr-Rowe hypothesis states that high-SES families enable children to fully express their genetic potential. • The compensatory advantage hypothesis claims that low genetic endowments have less impact on education for high-SES children. • We build polygenic indexes for cognitive and noncognitive skills to predict seven outcomes across three research designs. • The Scarr-Rowe hypothesis lacks empirical support, while the compensatory advantage hypothesis is partially validated.

Recent studies document a social-origins gap or direct effect of social origin (DESO) on labour market outcomes over and above respondents' education, challenging the idea that post-industrial societies are education-based meritocracies. Yet, the literature offers insufficient explanations on DESO heterogeneity across education and different labour market outcomes. Little is also known about underlying mechanisms. We contribute by answering two questions: (i) How does DESO vary when comparing college-degree holders with non-holders? (ii) For which specific parental and children's occupations is the largest DESO observed? We focus on Spain, using a large new dataset (n  = 144,286). Firstly, we find a larger DESO on socioeconomic status among non-degree holders, and on income among degree holders. We propose the notions of compensatory advantage in occupational attainment and boosting advantage in income for high social-origin individuals to explain these opposite patterns, drawing from 'downward mobility avoidance' and 'effectively maintained inequality' theories. Secondly, we map origin and destination micro-classes where DESO is largest. High-grade managerial and professional parental occupations, characterized by social closure and influence in large organizations, are the origin micro-classes exerting the largest DESO. We also find that compensatory advantage for low-educated children from advantaged origins is related to their higher chances of accessing managerial occupations, while boosting advantage on income among college graduates is observed for high-grade managers and liberal professionals, suggesting that micro-class reproduction may partially account for boosting advantage. We conclude by discussing the generalizability of our findings to other countries and their implications for research on DESO, meritocracy and social mobility. [ABSTRACT FROM AUTHOR]

Immigrant-origin students often hold higher educational aspirations than native-origin peers, accounting for socioeconomic status and school grades. The consequences of this 'Immigrant Aspiration Paradox' (IAP) on their socioeconomic attainment are debated. Although individuals' occupational aspirations and how they compare with their educational aspirations (i.e. their alignment) also affect status attainment, they are understudied in the IAP literature. We contribute to the debate on the benefits of the IAP by investigating immigrant-native gaps in the level, (mis)alignment, and (un)certainty of teenage occupational and educational aspirations and their consequences on educational attainment in Germany. First, we describe immigrant-native gaps in teenage aspirations. Then, we investigate whether these differences mediate immigrant-native gaps in upper secondary attainment and tertiary enrollment. In line with the immigrant optimism theory, Asian-origin and Turkish-origin students are more likely to hold aligned high aspirations. On average, immigrant-origin students are less likely to have aligned low aspirations compared to native-origin students, and equally likely to hold misaligned or uncertain aspirations. We find that students from most immigrant-origin groups have a higher upper secondary attainment and tertiary enrollment than native-origin students, net of controls. Large portions of these advantages are mediated by the aspirations of immigrant-origin students, which we interpret as evidence of the benefits of the IAP. [ABSTRACT FROM AUTHOR]
