In this study, Jaap Scheerens looks at most aspects of the school effectiveness panorama, thus providing a useful overview for educational planners. The author uses the school-effectiveness knowledge base to examine relevant approaches to improving effectiveness, although never loses sight of the fact that each situation is specific. He concedes that there seems to be more leeway for action the closer one gets to the school level, thus making planning for effectiveness difficult for those operating at the above-school level. Bearing this in mind, he suggests that a multi-level approach might be the most appropriate, particularly for developing countries. The importance of school self-evaluation is emphasized, as is the fact that the evaluation process in itself can contribute to enhancing effectiveness. On the basis of this booklet, planners will certainly be better geared for dealing with the different factors involved in improving school effectiveness
