Schoolzelfevaluatie: het evalueren van en door scholen

In this dissertation, a procedure for schools to evaluate the quality of their education is presented. The procedure is called EVADOS, a Dutch acronym for `evaluation of and by schools¿. Quality of education can be defined in several ways. In EVADOS, student achievement, in particular, achievement measured by test results, is considered to be the most important indicator of the quality of education. However, since the educational input and processes of schools are so different, it is not fair to determine the quality of a school on the basis of test results alone. The test results obtained by students have to be adjusted for differences in input and processes, and EVADOS makes it possible for schools to make this adjustment.
