How long should a classroom walkthrough last?
Five to fifteen minutes is the sweet spot. That's long enough to see meaningful teaching and learning, but short enough to be sustainable when you're visiting multiple classrooms per day.
A lot of leaders think they need to stay for a full lesson to "see enough." But brief, frequent visits actually give you a more accurate picture of everyday instruction than occasional long observations. A 45-minute formal observation shows you a teacher's best performance on a predetermined day. A five-minute visit shows you what Tuesday afternoon actually looks like.
The goal isn't to evaluate a single lesson — it's to build a running understanding of practice over time. When you visit a teacher 15-20 times over the course of a year, you develop a far richer picture than any single long observation can provide.
I discuss the rationale for brief visits and how they fit into a broader model in Now We're Talking!, Day 2.
