This paper examines the influences of parental social status, childhood cognitive ability, school motivation and education on social status attainment in early adulthood. Using Structural Equation Modelling (SEM), a pathway model of transgenerational status attainment is conceptualised, taking into account the context as well as the timing of individual status transitions. The subjects were 3104 men and 3229 women who participated in the 1958 National Child Development Study and 3049 men and 2692 women from the 1970 British Cohort Study, following their lives from childhood to their mid-thirties. The findings suggest that in both cohorts the number of years spent in full-time education is by far the most important determinant of status attainment among men and women and that there are persistent social inequalities in status attainment. The findings furthermore confirm the hypothesis that social background and cognitive ability are partially mediated through school motivation and education, opening up leverage for possible interventions.
