Learners with special educational needs have been increasingly integrated into regular education in Switzerland and internationally. However, not all learners in heterogeneous classrooms are able to meet the regular learning objectives. Reduced Individual Learning Objectives (RILZ) is an important measure employed in all Swiss cantons to ensure that all learners can be educated in mainstream classrooms.

The RILZCHECK project aims to analyse the patterns of allocation and the effects of the RILZ measure on learners’ educational achievement and attainment. The project draws on linked data from standardised school performance tests carried out in the cantons of Aargau, Basel-Landschaft, Basel-Stadt and Solothurn, which are analysed using established statistical methods. 

The project not only provides important findings for research but also contributes to an empirical basis for further development of RILZ by identifying conditions that may mitigate potential adverse effects.
