In the peer mentoring arrangement, a university- or tertiary-level student goes to the school to counsel young people regarding their studies. Longer days mean that students work more in school and spend less time on homework, this helps narrow household education climate and infrastructure gaps that affect learning. In addition, extending the school day can facilitate coordination between principals and teachers, and it can be used to attract a greater concentration of teacher hours in a single establishment (ECLAC, 2011b). A full school day has positive effects on the organization of family time and out-of-school care, too, as well as the incorporation of women into the labour market and the amount of time that children and young people are exposed to external risks (ECLAC, 2011b).
