Subclaims¶

q2 i? The literature does not conclusively identify a necessary dosage; coaching appears more sensitive to quality than dosage. → Schachner 2024 q2 i? For comprehensive coaching, the literature commonly finds coaching more effective when continuous over a sustained duration. → Schachner 2024 (2)

Evidence¶

q2 · i? · qualitative · r2

The report's review states no specific dosage is established and that coaching "appears more sensitive to the quality of coaching rather than the dosage." It reports studied dosages ranging from 3 to 32 sessions and sessions from a few minutes to 5 hours.

"The research literature does not conclusively suggest that there is a specific dosage (i.e., total number of hours, frequency, or length of sessions) necessary for effective coaching, but rather that coaching appears more sensitive to the quality of coaching rather than the dosage."

q2 · i? · qualitative · r?

The review reports that for "more comprehensive coaching," a common theme is greater effectiveness when coaching is "continuous over a sustained duration," noting early-learning coaching is implemented over an average of 5 to 7 months.

"However, for more comprehensive coaching, a common theme in the literature is that coaching is more effective when it is continuous over a sustained duration."

Related Claims¶

• Pairing coaching with group trainings is associated with larger effects on instruction and achievement; instructional materials with larger, and video libraries with smaller, effects on instruction — the general claim this finding bears on, with the studies behind it

• Coaching dosage shows precisely estimated null effects: more coaching hours are not associated with larger program effects — the general claim this finding bears on, with the studies behind it

• Supervisory teacher coaching shows mixed effects, with six of sixteen reviewed studies reporting improved teacher results and four reporting improved student behaviors — related

• In five scaled early learning coaching systems, coach-to-site ratios averaged about 1 coach per 22 sites, dosage varied widely, and participants perceived benefits in educator satisfaction, practice, and program quality — related
