The new legislation, Compulsory Education for 12 years (4+4+4) (see below), can improve student transitions between educational levels, but if not managed well, it can lead to more segregation among schools and further inequities. Currently, students are academically selected at age 13.5 and sorted into upper secondary schools based on results in a national examination. If the different pathways vary in quality, this can widen achievement gaps and hinder equity.
