This literature review looks at the different coaching models, how relationships effect successful coaching, the different roles a coach may experience, and the effects coaching can have on teachers and students. Over the past 10-15 years coaching in education has become a hot topic (Heineke, 2013). However, there is not much research or studies on the actual implementation of a coaching program and how it affects the students and the teachers. In this paper coaching roles takes on two meanings: what the coach does during a coaching session/meeting and what type of “hats” the coach wears during the time they are in the coaching position or career (Kane & Rosenquist, 2018; Wang, 2017; Heineke, 2013). The effects of coaching were classified into two categories: effects on teachers and effects on student achievement. Future research is needed to continue to close gaps.
