PD That Works For school leaders →
The comparison · For school leaders

Instructional coaching vs. professional development.

They're usually budgeted as the same line item, but they're different instruments. Workshops transfer ideas to many people at once. Coaching changes one person's practice over time. Schools that get results treat them as two halves of one system — and the interesting question in 2026 is what fills the gap between them.

Why coaching wins on change — and loses on math

The research consensus is uncomfortable for the workshop model: ideas transfer in sessions, but practice changes through cycles of trying, feedback, and adjustment — which is what coaching is. The problem was never whether coaching works. It's arithmetic: a skilled coach can hold a few dozen real relationships, and almost no school can afford one coach per teacher, every day. So coaching gets rationed, and most teachers get the workshop and nothing else. That's why PD doesn't stick.

Not either/or

The emerging structure keeps all three instruments doing what each does best: the workshop introduces the idea and sets a specific, coachable goal; daily AI follow-up keeps that goal alive five minutes at a time, every teaching day; and human coaches spend their scarce hours where human judgment matters — in classrooms, in modeling, in the conversations an AI shouldn't have. We're explicit about the boundary: we make coaches better, we don't replace them.
