Abstract

The paper describes the procedure for measuring performance of general educational institutions, using the linear quality scale. Such assessments are
 essential to monitoring and compare performance of general education schools. The questionnaire is developed to carry out operational measurement
 of schools� performance as the set of indicators. The questionnaire is considered to be the tool for measuring the quality level of schools� performance
 against the linear scale and helpful for monitoring and comparative analysis of schools. The analyses of the questionnaire quality and of the general
 educational schools� performance assessment are carried out within the frameworks of the latent variables theory, based on the Rasch model. The
 indicators, which fit better than others for differentiating between schools with poor and high performance levels, are discussed, as well as indicators,
 considered as the most adequate and the less adequate for the assessment model. Characteristic curves of these indicators are provided. Positions
 of schools assessed and of indicators are shown against one and the same linear scale of �school performance quality�. Results obtained are used to
 compare quality of various schools� performance. As it is shown, the difference between lyceums and general education schools by the latent variable of
 �performance quality� is wider, than difference between secondary and general education schools.
