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...

Prosocial behavior at school, such as helping and sharing, contributes to positive individual development, peer relations, and classroom climate. Students with intellectual disabilities (ID) may have difficulty to demonstrate prosocial behavior, but little is known about the levels of prosocial behavior and its predictors in this population. This s...

Background: Children and adolescents with intellectual disabilities (ID) are at increased risk of developing challenging behaviour. Challenging behaviour may be partially explained by low individual communicative competences. However, communication involves at least two partners, thus outcomes may also vary according to each interaction partners'...

Adolescents are frequently faced with decisions characterized by an affective component, such as those that take place among peers or include the promise of a reward. In such situations both cognitive and affective control are necessary for optimal decision making. A lack of either can contribute to risk-taking behaviors and social vulnerability. I...

Children and adolescents with intellectual disabilities (ID) exhibit low levels of adaptive behaviors (i.e., conceptual , social, and practical skills).

Previous research suggests that the 1st year in secondary school for some students goes hand in hand with an increase in adjustment difficulties. One factor that might influence this process on an individual, compositional, and institutional level is the academic track a student attends.
