This study examined the effects of coaching changes on team performance in the English Premier League. There is currently discussion on the specific effect changing a head coach has on team performance (negative impact, positive impact, no impact). This study contributes to the on-going discussion by examining the timing of coaching changes (between-season, within-season) and its impact on team performance. Performance data were collected on soccer teams in the English Premier League between 2000/2001 and 2018/2019 that experienced coaching changes. A series of ANOVAs and t-tests were conducted in order to determine how team performance differed after a coaching change occurred. Results suggest that regardless of the timing of the coaching change, performance levels increased and stayed elevated for at least one-and-a-half seasons following the coaching change. Further research should be conducted to determine how long this effect lasts, and to determine which type of coaching change results is best.
