The children with special needs should be care of every society and more attention should be paid to them. Such children are separated in many communities and go to special schools. Fortunately these schools are decreasing in number, because there intention to include them into regular schools. However, if the degree of retardation is too high and disables them to follow the standard syllabus, they go to special schools. In previous researches great correlations have been spotted between certain anthropological features and levels of retardation. In this work we have concluded that students with the high level of retardation differentiate largely in morphological characteristics and movement abilities. These differences were huge, students with mental retardation were 18 kg heavier than normal students of the same age. That of course had impact on their movement abilities, especially on coordination which is very important for a complete motorical movement. Students with mental retardation have shown a much lower level of movement abilities in general than the students who came from the normal population because the movement abilities are in important correlation with all psychological manifestation in people. By working on developing of movement abilities we ca definitely affect the improvement of their psycho-physic functions.
