This paper proposes a measure of self-efficacy expectations with regard to tasks required in guiding and advising in career indecision, decomposing into a career counseling process, information-searching, and outcome expectation factor. The proposed measure of career guidance self-efficacy is based on Bandura's self-efficacy theory and self-efficacy measure developed by O’Brien, Heppner, Flores and Bikos. A total of 143 teachers in 6 commercial high schools were administered the measure of self-efficacy for career guidance. Statistical results indicate that commercial high school teachers, in general, express considerably low level of confidence in their ability to give career guidelines and reduce the career indecisions. In addition, the strength of teachers' career-guidance self-efficacy were found to be strongly related to whether they have ever been trained in the field of career guidance.
Others factors were tested not to be significant to the self-efficacy level. Practical guidelines for
improving the strength of teachers' career guidance self-efficacy are provided.
