This study investigated self-esteem, parenting style and gender as predictors of achievement motivation among adolescents. There were two hundred and fifteen (215) adolescents (97 males and 118 females), ages ranged from 10 to 18 years who participated in the study. Cross-sectional survey design was adopted for the study. Three instruments were used for data collection: the Index of Self-esteem; the Parenting Care Scale and the Achievement Motivation Scale. Hierarchical multiple regression statistic was employed for data analysis. Five null hypotheses were proposed and tested in the study. Results showed that self-esteem, permissive and authoritarian parenting styles significantly predicted achievement motivation among adolescents, while authoritative parenting style and gender were not significant predictors of achievement motivation among adolescents. Implications for educational system for the restoration of its fallen standard were highlighted. Limitations of the study were stated and suggestions equally made for further studies.
