“…The scope of school integration varies according to public policies and social relations between families often involving competition (Verdier, 2010), but also mainly according to the regulation of institutional practices (Iannelli, 2013). Even in the presence of a common program, the reconfiguration of the link between social and educational inequalities can be maintained through socially accepted practices of segregation in institutions: for example, parents' right to choose their children's school (Van Zanten, 2009), the link between the quality of institutions and the social organization of neighborhoods, which favors socially homogeneous student groupings in the same schools (François & Poupeau, 2004), learning differentiation and the proliferation of optional courses (Felouzis, 2009;Kamanzi, 2019;Kamanzi et al, 2020), the autonomy of institutions to adapt or reorganize programs, as well as competition between institutions (Draelants, 2013;Kamanzi, 2019).…”
