Previous research has shown that students with special educational needs (SEN) have fewer friendships than their peers without SEN. In this longitudinal study, 545 students from primary and secondary schools, including 106 students with SEN, were surveyed at the beginning and the end of the school year. The results show that students with SEN generally have fewer reciprocal friendships and, proportionally, more often nominate students with SEN than students without SEN. The stability of friendships is lower for students with SEN than for students without SEN. Additionally, for students with SEN, same-SEN-status friendships were as stable as cross-SEN-status friendships, whereas for students without SEN friendships with peers without SEN were more stable than those with peers with SEN.
