ABSTRACT
One of the most consistent lines of inquiry in the literature relating to self-concept regards the possible link between self-concept and the various measures of performance or achievement. Wylie (1979) has pointed out that many persons, especially educators, have unhesitatingly assumed that achievement and ability indices are strongly related both to self-assessments of achievement and ability and to overall self-concept. The general opinion is that a moderate and positive association exists between self-concept and measures of performance and achievement. A cursory assessment of the literature, however, suggests that this relationship is neither precise nor clear. In fact, given the volume and diversity of research literature, all viewpoints can be supported.
