The thesis focuses on dynamic evaluation of younger pupils with mild mental retardation by application of a Visual Perception Test, which evaluates certain areas of sight perception. It is an alternative diagnostic method focused on rational intervention, which applies diagnostically obtained findings and results in search for adequate assistance and support of the particular pupil. In the theoretical section, the text focuses on pupils with mild mental retardation, their specific features and education. It introduces basic findings on dynamic diagnostics and dynamic approach and its application in support of pupils with reduced intellect. In the empirical section, the research seeks to verify whether the test, which evaluates selected aspects of sight perception, is a suitable tool for dynamic examination of children with mild mental disabilities and whether and in what form of intervention, the pupils who have been included in the research project experience different results in the pre-test and post-test. Based on the detected results, the Visual Perception Test appears to be a very effective tool in dynamic diagnostics for individuals with mild mental retardation. In the conclusion and the recommendations, the work presents the detected suitable forms of intervention for each particular pupil.
