Quality requirements in all areas of education and in all types of schools are one of the basic attributes on which the future of nations, states and humanity depends. The quality of education as a service of a publicly funded society is therefore subject to monitoring by government institutions. Evaluating the quality of a school means finding out data on pre-agreed aspects of school life, the processes that take place in it. In 2015, an innovated state educational program was introduced in primary education. It brought changes especially in the educational standards of individual subjects, where is the attention to performance standards. The content of the curriculum does not become the goal of education, but a means to achieve the goal, which is a competent student. National testing also tries to bring this change in the understanding of content closer to the creation of test tasks. Students tests results cannot be the only and most important measure of a school's quality. Students, parents and teachers need to focus on non-cognitive processes at school. The introduction of testing of 5th grade students was not accepted by teachers with an understanding of effort to increase the quality of education. The aim of the paper is to compare the opinions of teachers from 2017 with the opinions of teachers in 2020 and to find out whether there has been a change in the acceptance of testing of 5th grade students as a tool for measuring the quality of education after primary education.
