This study aims to explore the effect of peer coaching on instructional skills. 50 students attending Bartın University, Turkish Teaching Undergraduate Program participated in this mixed-methods study with explanatory sequential design. Quantitative data were collected with the Micro Teaching Evaluation Form and qualitative data were collected with a semi-structured interview form. t-test and content analysis were used in the analysis. It was found that there were significant differences in favor of the experimental group in the dimensions of lesson planning, lesson-opening, development of the lesson and overall success while the data yielded significant differences in favor of the control group in the knowledge and communication dimensions. Yet, there was no significant difference in lesson-closure dimension. Participants stated that peer coaching contributed positively to professional development, sharing of opinions and experiences, and affective development. Coachees were found to be enjoying microteaching, spotting their mistakes in advance, learning by having fun and asking questions to the coaches at any time. Participants were concerned that peer coaching interfered with creative thinking. Integrating peer coaching in the curriculum, encouraging peer coaching after preparation of lesson plans, and collecting reports from the students at each stage are among the educational implications recommended.
