摘要教育研究中的学校效能评估是从统计建模的角度来考虑的。各种各样的模型应用于一组数据907名学生在18所学校从一个地方教育局。我们认为，一般使用方差分量或“随机参数”模型的分析，这些研究涉及聚类观察。对于所研究的数据，回归学校的平均结果对学校的平均摄入量的模型（即“手段”模型）显示，估计学校的影响相当不同，从其他模型产生的。根据我们的研究结果，我们评论最近几个大规模的英国学校的有效性研究。
SUMMARY The assessment of school effectiveness in educational research studies is considered from the viewpoint of statistical modelling. A variety of models are applied to a set of data on 907 pupils in 18 schools from one Local Education Authority. We argue for the general use of variance component or "random parameter" models for the analysis of such studies involving clustered observations. For the data examined, the model which regresses school mean outcome on school mean intake (i.e. the "means on means" model) is shown to give estimated school effects considerably different from those produced by other models. In the light of our results, we comment on several recent large-scale British studies of school effectiveness.
