Abstract
Previous researches suggested that many children with mild mental retardation became unable to attend school from the onset of puberty, because their negative self evaluation was growing stronger due to the ill treatment of surrounding people such as teachers, parents, and peers. Howerer, some studies revealed that they showed the negative self evaluation only about their academic self, but not about global self-esteem. This was a case study of a fourth grade boy with mild mental retardation, who could not go to school during the second term but was later able to do so, was analyzed from the viewpoint of the positive or negative self evaluation and the accuracy and stability of self perception. Until he began to go to school, he couldn't express both the negative and the positive self evaluation. Before that, his self evaluation was fluctuated and quickly changed according to the situation and to other's behavior. Also, his self perception was not accurate and stable. The role of significant others who effected the modification of his self perception and self evaluation was discussed.
