Transition to secondary school implies basic changes in social, instructional and organisational aspects of school life which afford the pupils’ adjustment. As transition takes place at a predictable point in time, children develop expectations about the start at their new school. In order to analyse predictors and consequences of these expectations 870 German children filled in a questionnaire assessing transition expectations, grades in mathematics and language, academic self-concept, and school dislike. Achievement tests were administered, too.
