Illinois SB 2909 (Public Act 104-0565) is the first US law on AI in teacher evaluation. What it actually says: AI can't assign the score or rating, but may support the administrative write-up. Teachers are covered too. Effective Jan 1, 2027.
AI can cut a teacher evaluation in half, but which half? The watching (human judgment) must stay human; the writing (rubric translation) is what AI can safely do. Why that line is the whole question, and why the write-up tool you pick still matters.
Whether an AI-assisted teacher evaluation holds up depends on the process, not the AI itself. The four properties that make any evaluation defensible, where AI helps, where it adds risk, and what to ask before it reaches a personnel file.
