The purpose of my study was to develop and validate a scale to assess peer mentoring practices that aim to enhance learning. In the development process, 4 focus group interviews were conducted with 10 mentors and 12 mentees who participated in 8 weeks of peer mentoring. In addition to the literature, the findings from interviews were used to develop items. The 11-item form was administered to 126 college students. After the confirmatory factor analysis, the scale took on its final form with 10 items in 3 factors as Contribution to Mentee, Mentor Characteristics, and Peer Relationships. The results of confirmatory analysis were: GFI 0.92, CFI 0.99, NNFI 0.98, RMSEA 0.080, and Cronbach a coefficient was found to be 0.954.
