This paper examines the conceptual foundations of self-concept, self-esteem and the self as they relate to disabled students in the context of physical education. Disable school children experience severe discriminations in society and within the school system, especially if the school is the mainstream type. With increasing emphasis on inclusiveness in school to different groups of excluded children, the need to thoroughly examine the psychological frame of mind of these children is now more important than ever before. Consequently, this paper sought to uncover the fundamental tenets of self-concept of disabled learners and highlight the key characteristics of disabled children. The paper concludes by with an analysis of the major impacts that disabled learners self-concept has on participation in physical education activities.
