This study examined the achievement and its relationship with achievement motivation and self concept. The subjects consisted of 336 students (146 males and 172 females) from four public and four private schools of the Sargodha district at the secondary level. Intact groups of all eight schools enrolled in 9th grade were involved in the study. An Urdu translated version of "Academic Self-Description Questionnaire II" (Marsh, 1990) and "General Achievement Goal Orientation Scale" (McInerney, 1997) was used. The results revealed that achievement motivation and self concept are significantly related to academic achievement. Significant gender differences were discovered which were in favor of girls. It was suggested that teachers must use motivational strategies to involve students in academic activities for improving their grades.
