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.

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.
