The purpose of this study was to investigate the relationship between the academic achievement and the need for achievement and the need for affiliation for high school students of Oman. Further investigation was carried out if there was a significant difference in the needs for achievement and affiliation between high G.P.A. students and low G.P.A. students as well as between males and females. A self-rating form of 75 items derived from the Edwards Personal Preference Schedule was used to measure the fifteen needs listed by Duncan Osborne (1963). However, the scores on ten items pertaining to need for achievement and need for affiliation were used in this study. Academic achievement was measured by the scores on school tests from the Interior Province of Oman. The results indicated no significant correlation between the academic achievement and the need for achievement and the need for affiliation. The results also showed no significant difference between high G.P.A. students and low G.P.A. students as well as between males and females on either the need for achievement or affiliation.
