Using data from Birth to Twenty, a cohort of South African urban children, the current paper investigates the relationships between residential and school mobility and a set of educational outcomes. The findings provide some evidence of a positive association between changes in residence and numeracy and literacy scores, and school mobility was found to be associated with grade repetition, however, no relationship was observed between changes in school and competency in numeracy and literacy. The South African study provides a counter example to trends observed in higher-income countries, while highlighting that associations are likely to be context specific.
