This study investigated relationship between self-concept and academic achievement of bachelor degree students. Female students at bachelor were considered the target population. A sample of 1500 students was selected by using two stage cluster sampling technique. An amended form of Self-Descriptive Questionnaire developed by Marsh (1985) was used as tool of research. Factor analysis was employed to explore the pattern of inter-item correlations of the questionnaire. Kendall's-Tau-b technique of correlation was applied to correlate responses obtained on academic, physical and social self concepts related items with the academic achievement scores of students Physical self-concept and social self-concepts were found unrelated to academic achievement. However, a significant but weak correlation was found between academic self-concept and academic achievement.
