AI Teacher Evaluation Tools: 8 Questions to Ask Before You Buy

From “Gotcha” to Ground Truth: How Live Transcription Protects Teachers from Evaluator Bias

Ask a veteran teacher about their evaluation history and you’ll usually hear the same story: an administrator typing in the back of the room, and a write-up weeks later that doesn’t match the lesson they taught.

AI in Teacher Contracts: What Evaluation Language Should Cover

AI protections are already appearing in teacher contracts, including in evaluation and discipline. The next step is specific rules for how AI is used in observations and evaluation write-ups, agreed with teachers before a pilot rather than after a dispute.

The Power of Thought Partners in Education

I've been observed plenty of times in twenty-two years of teaching. What I remember is a coach who asked one question I couldn't answer. That question changed how I taught more than any rating on any form ever did.

What “Doing More With Less” Actually Costs in Teacher Observation

A thorough observation cycle takes two to four hours per teacher. Multiply that by a full staff and the total stops fitting into a principal’s week. So the work gets cut down—and the cost of that compression is real, even if it never shows up on a budget line.

Kim Marshall Is Right About AI in Teacher Evaluation. He’s Also Not Going Far Enough.

Marshall drew a sharp line between AI that supports the human work of evaluation and AI that tries to replace it. That distinction is the right one. But “well-crafted” is doing a lot of heavy lifting, and most AI teacher evaluation tools on the market don’t meet the bar.

The Hidden Weight of Teacher Observations: An Administrator’s Reality

“Human in the Loop” Has Become the AI Safety Equivalent of “Thoughts and Prayers”

There’s a phrase that shows up in nearly every enterprise AI pitch deck: “Don’t worry, there’s a human in the loop.” Except the research on how humans actually interact with AI systems tells a very different story.

Your Principals Are Already Using AI to Write Teacher Evaluations. Here’s Why That Should Worry You.

Administrators are sitting in a classroom, taking observation notes, and then pasting those notes into ChatGPT or Google Gemini to help draft their teacher evaluations. They’re not doing it to be reckless. They’re doing it because the current evaluation process is broken.

When "You're Doing Great" Isn't Enough

For many years, I was a proficient teacher. My classroom was efficient, students were engaged, and learning was happening. But over time, I realized something was missing. What I wanted was feedback that honored my success and still helped me grow.
