A very important element of the youth athletic experience is the coach, who plays a key role in the athletic and personal development of each player. This research explored whether the incorporation of professional training enhanced coaching efficacy for youth sport coaches. The domains of coaching efficacy measured included character building, teaching technique, game strategy, athlete motivation, and total coaching efficacy. Participants included 26 volunteer youth athletic coaches. A concurrent, triangulated, mixed method, phenomenological study was conducted using pre-post surveys for all participants in this study. In addition, interviews were conducted to confirm and cross-validate findings within the study. Quantitative data were analyzed by calculating descriptive statistics for the four dimensions of coaching efficacy. An analysis of covariance determined whether the dimension means were significantly different from each other. Qualitative data were coded using inductive analysis to identify categories that emerged from the findings. The results indicated that parent and athlete perceptions of coaches did not differ among coaches exposed or not exposed to the treatment. When comparing the four dimensions of coaching efficacy and total coaching efficacy, there was no significant difference between coaches exposed to the training and those in the control group. The positive change implications include the potential impact of coaching education programs to improve the quality of sport experiences for youth. As a result, young athletes might experience increased skill development along with numerous social and emotional benefits.
