Mentoring is widely advocated as an educational experience for academically talented students because mentors may provide stimulation for academic growth and serve as positive role models for students in areas of career interest. This study examined the experiences of 72 talented teenagers attending a university-based summer mentorship program. Students completed pretest and posttest measures assessing self-concept and perceptions of research aptitude; they also shared their perceptions of their mentoring relationships in written journal entries. Results demonstrated increases in students' perceived research skills and job competence; students reported positive relationships with mentors, particularly when they felt that their mentor spent a great deal of time with them and was approachable, friendly, and engaging.
