Despite the common title of “coach,” definitions of high-quality coaching vary tremendously across models and programs. Yet, few studies make comparisons across different models to understand what is most helpful, for whom, and under what circumstances. As a result, practitioners are left with many options and little evidence-based direction. This is exacerbated by the literature’s focus on more abstract features of coaching practice (e.g. building trust), leaving practitioners to figure out what concrete discourse strategies support these goals. This paper begins to address these challenges by introducing a taxonomy of coaching “moves,” parsing the concrete details of coach discourse. While the taxonomy is informed by the literature, it highlights conceptual possibilities rather than providing a list of empirically-grounded or “evidence-based” strategies. In doing so, this taxonomy may serve as a common language to guide future work exploring how coach discourse shapes teacher development, synthesizing across studies, and supporting coach practice.

Teacher preparation programs are increasingly expected to use data on pre-service teacher (PST) skills to drive program improvement and provide targeted supports. Observational ratings are especially vital, but also prone to measurement issues. Scores may be influenced by factors unrelated to PSTs’ instructional skills, including rater standards and mentor teachers’ skills. Yet we know little about how these measurement challenges play out in the PST context. Here we investigate the reliability and sensitivity of two observational measures. We find measures collected during student teaching are especially prone to measurement issues; only 3-4% of variation in scores reflects consistent differences between PSTs, while 9-17% of variation can be attributed to the mentors with whom they work. When high scores stem not from strong instructional skills, but instead from external circumstances, we cannot use them to make consequential decisions about PSTs’ individual needs or readiness for independent teaching.
