School placement trajectories of students with special educational needs-A longitudinal analysis of administrative data

School transfers may be particularly challenging for students with special educational needs (SEN), and may negatively impact academic and social outcomes for these students. In countries with multiple placement options for students with SEN, although transfers between different types of placements are plausible, studies on this phenomenon are rare. The current study investigates individual placement trajectories over 11 years of compulsory education, using administrative data from a Swiss canton (i.e. federal state) about students with intensive SEN support. We employed sequence analysis to describe individual characteristics of placement trajectories (type of placements attended, number and timing of transfers), and to identify typical placement trajectories. Findings indicate that students with SEN experience frequent placement transfers, however, high variability between individual placement trajectories exists. Four clusters representing typical placement trajectories emerged. The clusters differed in the placements predominately attended by students, the number of transfers experienced, as well as in the distribution of students' age, gender and first language. These differences may reflect variations between clusters in the type and severity of students' SEN. Our study results underscore the importance of understanding the dynamics of placement trajectories for students with SEN, contributing valuable insights into the complexities of their educational journeys.
