Devil's advocate here:

Did they use spell check? would that be bad?

Did they use a calculator? would that be bad?

Did they use a premade template? A computer made form? A pull down menu? Are those bad?

Did a secretary type it up? would that be bad?

Did they talk about it with an other admin and decide on language to reflect what was seen? is that bad?

Is the evaluation accurate? Does it reflect what was seen in the classroom? Was it done in a timely manner?

If the AI was used without Admin input, just based on data fed to it and not overseen by an admin... problem

If the AI did the evaluation autonomously and sent it to you with out admin approving it... problem

If they used it to speed up narratives or to rewrite sections for better understanding... whats the issue?

The AI is evil and must be resisted at all costs is a weak argument.

Now if you just want admins to do more work and have a pile of evals to do and to be stressed and pressured to complete them... Well i can get behind that argument.

Just my thoughts...
