The Case for Peer Observations: Why Teachers Should Be in Each Other’s Classrooms

There is an enormous amount of expertise sitting untapped in school buildings across the country. Teachers who have figured out something remarkable about classroom management, about formative assessment, about how to reach a student who has shut down — and who share almost none of that expertise with the colleagues twenty feet down the hallway.

This isn’t a criticism. It’s a structural observation. Schools aren’t built to transmit teacher knowledge laterally. Professional development flows downward — from district to school to teacher — and the learning that happens in individual classrooms stays there, invisible to everyone else.

Peer observations are one of the most powerful and underused tools for changing that dynamic.

What Peer Observation Actually Is

A peer observation is a structured classroom visit conducted by one teacher for the purpose of learning from another — not evaluating them. Like coaching walks, the distinction from evaluation is non-negotiable. The moment peer observation becomes hierarchical or judgmental, it stops working.

The best peer observation programs are built around reciprocity and genuine inquiry. Teachers identify something they want to learn — a practice they’ve heard about, a challenge they’re wrestling with — and visit a colleague who has developed something relevant to that question. The observer brings curiosity, not a clipboard. The observed teacher brings openness, not a performance.

There is an enormous amount of expertise sitting untapped in every school building. Peer observations are one of the most powerful tools for changing that.

The Research Case

The evidence for peer observation as a professional learning strategy is strong. Research suggests that teachers who observe their peers and engage in structured debriefs after those observations develop their practice faster than those who receive traditional professional development alone. The mechanism makes intuitive sense: seeing a practice in action, in a real classroom with real students, is fundamentally different from hearing about it in a workshop.

What’s less intuitive is the benefit to the observed teacher. Being visited by a trusted colleague — someone who brings genuine curiosity and no evaluative agenda — produces its own kind of professional reflection. Teachers often report that being observed by a peer helped them see their own practice more clearly than feedback from an administrator ever had.

How to Build a Peer Observation Culture

The schools that develop thriving peer observation cultures do a few things consistently. They start with relationships — making sure the first peer visits happen between teachers who already trust each other. They build in structured debrief time, because an observation without a conversation is just surveillance. And they connect peer observation to the school’s instructional goals, so visits aren’t random learning experiences but deliberate contributions to a shared improvement agenda.

They also make it logistically possible. Peer observation fails in schools where teachers can’t find coverage, where schedules don’t create natural time for visits, or where the administrative burden of arranging an observation is high enough to make it feel not worth the effort. Removing friction is as important as building culture.

The Data Question

One challenge schools face with peer observation is what to do with the data it generates. When an administrator conducts a walk, there’s a clear system — however imperfect — for capturing and using that data. When a teacher visits a colleague, the insights often stay in a mental note or a brief conversation that doesn’t connect to the school’s broader improvement work.

The schools that get the most value from peer observation find ways to connect it to the larger picture of instructional practice — not to evaluate teachers based on what their peers observed, but to enrich the school’s understanding of what’s happening across the building. When peer observation data sits alongside coaching walks and learning walks, the school gets a more complete, more honest view of its instructional reality. And the culture of observation becomes something that belongs to everyone in the building, not just to the people with administrative authority.
