Abstract

General conceptions of quality management in education are discussed. It is shown that to make decisions of quality control more reliable and objective quantitative evaluation approaches should be used. The approach should be consisting of two stages: 1. elaboration of unitary scaling systems for student’s grades and 2. clear definition of quality standards. The first stage can be realized by means of equating methodology, particularly by means of equipercentile equating whereas the second one – by means of methodology of contingency tables. The methods allow: 1.comparing of distributions of grades of different subjects in different times and 2. on the base of historical (for the given educational institution) teaching level data specifying quality standards and their confidence levels.
