Research on the well‐being of teachers was conducted at the request of the Department of Education in Flanders, Belgium. The goals were: to construct an instrument for the Education Inspectorate; and to conduct a survey in order to identify school‐related conditions relevant for teachers’ professional well‐being. Based on literature and panel discussions with teachers and principals, a questionnaire was constructed, tested and subdivided in subscales following a factor analysis. The questionnaire was administered to a representative sample of elementary and secondary (...) school teachers. A multilevel analysis reveals how differences in scores can be explained at school level. (shrink)
