Using Young Lives longitudinal data from Peru, this paper explores the relationship between socio-economic status (SES) measured at the age of 1, opportunities to learn (OTL) and achievement in mathematics by the time children were in fourth grade of primary school. Four variables of OTL were measured: hours of class per year, curriculum coverage, quality of teachers' feedback, and level of cognitive demand. The last three were measured through an analysis of the exercises attempted by students in their notebooks and workbooks.
