This article performs exploratory research using a mixed-methods approach (structural equation modelling and a thematic analysis of interview data) to analyse the ways in which socioeconomic disparities in voting patterns are reproduced through inequalities in education in different national contexts, and the role of self-efficacy in this process. The evidence suggests that in Germany and England students with lower socioeconomic status (SES) have lower levels of general self-efficacy, and that this is reinforced through early experiences of inequalities in the education system, such as within- or between-school selection. Low levels of general self-efficacy are then found to reduce political self-efficacy and voting intentions. In Germany and England, it is these students who enter initial vocational education and training (IVET). The experience of IVET then reinforces the distinctions in civic engagement, probably either through peer socialisation and/or curriculum differences. In Denmark, where SES has a weaker association with track placement, the experience of being placed in IVET plays a stronger role in reducing political self-efficacy and voting intentions.
