Especially for new teachers, doing certain small actions or interactions right in the classroom can have an outsized impact on becoming a solid teacher. And when experienced teachers guiding other teachers' growth is expected within a school, novices can master discrete skills very quickly--provided the school culture makes practicing well-understood skills until "perfect" the norm. Bambrick-Santoyo shares part of a scope and sequence of central skills that any coach guiding a new or struggling teacher should take that teacher through, with focused practice at each stage. An extended example shows how coaches at schools he's worked with use this sequence in guiding teachers to improve rapidly.
