Explaining stability and changes in school effectiveness by looking at changes in the functioning of school factors

This paper investigates the extent to which changes in the effectiveness status of schools can be related to changes in the functioning of school factors included in the dynamic model of educational effectiveness. The methods of a follow-up study were identical to those of a study conducted 4 years ago in order to test the validity of the dynamic model. Since the follow-up study took place in the same schools where the original study took place, changes in the effectiveness status of schools and in the functioning of effectiveness factors were identified. Discriminant function analysis reveals that changes not only in the functioning of some school factors but also in the quality of teaching practice can help us classify the schools into those which improved their effectiveness status, those which remained equally effective, and those which even reduced their effectiveness status. Implications of findings for the development of educational effectiveness research are drawn.
