The purpose of this study was to examine relations among maternal accuracy in predicting their children`s perceptions, their children`s actual self-perceptions about their abilities, and their children s level of cognitive and social development. One hundred thirty-one Korean preschool children, their mothers and their teachers participated in the study. Maternal predictions seemed to be related with children`s actual development while children`s self-perceptions were in general unrelated to their own development. Mother`s predictions were weakly related to her child`s perceptions, but this tendency became stronger with the child`s age. Mothers who had accurate ideas of their children`s perceptions tended to have children with higher levels of development.
