Advancing the science of coaching in education: An introduction to the special issue

School-based coaching has emerged as an effective approach for enhancing school personnel's knowledge, implementation skills, and wellbeing, as well as student achievement and behavior. This article introduces the special issue Advancing the Science of Coaching in Education, highlighting four large-scale, rigorous investigations on the effects of coaching and possible contextual variables that influence effective coaching in education. Two studies (Glover et al., 2022; Pianta et al., 2022) assessed how components of coaching (e.g., feedback, practice) may mediate or moderate classroom practices and/or teacher-student interactions that lead to improved student learning. One study (Pas et al., 2022) examined fidelity profiles of motivational interviewing embedded coaching on classroom practices and student behavior in middle school. The final study (Reddy et al., 2022) examined the effects of behavior support coaching on paraprofessional implementation of research-based behavior interventions, wellbeing, and elementary school student social behavior. This article spotlights common elements across studies and offers directions for research and innovation. The special issue closes with a commentary (Erchul, 2022) on the contributions of school consultation research to contemporary coaching research and offers recommendations for bridging research to practice.
