摘要：This paper deals with problems of self-selection and nested effects which often are met in evaluation of education processes, typically schools and training programs. To solve these problems models are proposed which extend to the qualitative dependent variable case results already known for quantitative dependent variables. A variance component model is moreover considered which simultaneously may treat nested effects and self-selection aspects of the considered phenomena.
