Primary and Secondary Effects in Class Differentials in Educational Attainment

Abstract

In this article we start from Boudon's important, but still surprisingly neglected, distinction between 'primary' and 'secondary' effects in the creation of class differentials in educational attainment. Primary effects are all those, whether of a genetic or socio-cultural kind, that are expressed via the association between children's class backgrounds and their actual levels of academic performance. Secondary effects are those that are expressed via the educational choices that children from differing class backgrounds make within the range of choice that their previous performance allows them. We apply a method introduced by Erikson and Jonsson to represent the relationship between primary and secondary effects in analysing class differentials in one crucial transition within the English and Welsh educational system: that which children make at around age 16 and which determines whether or not they will pursue the higher-level academic qualifications -A-levels -that are usually required for university entry. We then use a development of this method that we have earlier proposed in order to produce quantitative estimates of the relative importance of primary and secondary effects as they operate within this transition. We show that secondary effects reinforce primary effects to a substantial extent, accounting for at least one quarter, and possibly up to one-half, of class differentials as measured by odds ratios. In conclusion, we consider some theoretical and policy implications of our findings.keywords: class origin ◆ educational inequality ◆ England and Wales ◆ primary effects ◆ secondary effects

Why Do Some Young Adults not Graduate From Upper-Secondary School? On the Importance of Signals of Labour Market Failure

“…The other main result is that the probability that the young person did not graduate from upper secondary school increased substantially with the proportion of adult persons with a post-secondary education that receive unemployment benefits or social assistance in the neighbourhood. upper secondary is related to grades from or non-completion of compulsory school, and whether achievement in compulsory school is also related to the variables we study for example similar to the analysis in Jackson et al (2007) Our results also indicate that there is also scope for further qualitative research and for surveys that combine socio-economic and neighbourhood conditions with data on attitudes as in Mickelson (1990).…”

Changes in educational inequalities in Poland. Comments on Zbigniew Sawiński’s article “Education reform and inequality: fifteen years of new lower secondary schools in Poland”

“…Secondary effects include, e.g. situations where choices made by students with a similar level of skills vary due to the socio-economic status of the family (see : Jackson, Erikson, Goldthorpe and Yaish, 2007). When it comes to choosing secondary school, educational inequality is evidenced not only by the total effect of SES, but also the direct (not mediated by student skills) effect of this indicator on the choice of school.…”

El peso del origen social y del centro escolar en la desigualdad de resultados al final de la escuela obligatoria

“…Es decir, existe abundante evidencia de que las probabilidades de tener mayor éxito escolar aumentan cuanto mayores son los niveles de instrucción de los progenitores (Carabaña, 1993;Calero, 2007;Forquin, 1985;Jackson et al, 2007), pero en general se trata de correlaciones débiles o muy débiles, que responden a una considerable variabilidad interna dentro de cada clase social o de cada nivel de instrucción familiar. Esta variabilidad se pone de manifiesto en el diferencial de logro educativo de los hijos de clase trabajadora.…”
