How curriculum modifications shape educational pathways: Evidence from linked administrative data in Switzerland

British Educational Research Journal, EarlyView.
Abstract The increasing heterogeneity of learning needs and preconditions in inclusive mainstream classrooms entails that not all learners are equally able to meet the regular learning objectives. In response, various integrative measures have been implemented to tailor instruction to students' individual needs.
