The study aims to investigate the effectiveness of career guidance program in developing career planning skills using creative thinking strategies among academic gifted ten grade students in Muscat. The sample of the study consisted of (102) female and male students that was divided into two groups. The experimental group consisted of (50) male and female students while the control group consisted of (52) female and male students, the experimental group underwent career guidance program while the control group underwent activities in career guidance classes. The study adopted the quas-experimental method, the researcher used Career Planning Scale after verifying its psychometric properties. The scale consisted of (48) statements divided into six dimensions: Knowledge of the World of Work, Self-Knowledge, Knowledge of Occupations, Career Decision-Making, Career Planning, Career Implementation. The Cronbach's alpha score of Career Planning Scale was (0.95). The results of the T-test showed differences with statistical significance between the average response of the members in the experimental group and the control group on all Career Planning Scale dimensions in the postexperiment implementation in favor of the experimental group, while the results of the same test showed differences with statistical significance between the average of the experimental group in pre and post implementation on all Career Planning Scale dimensions in favor of the post implementation. The results of two way ANOVA analysis showed no statistically significance differences on the gender variable on Career Planning Scale. The same results showed that differences in performance with regard to the interaction effect between gender and group had no statistically significance differences. The results of the T-test showed also that there was no differences with statistical significance between the average of the experimental group in post and post 2 (follow up) implementation on all Career Planning Scale dimensions. Implications for future research and recommendations were discussed.
