If I understand correctly, you are looking for a transaltion for a survey that is conducted with the purpose of evaluating the teachers. This is probably a questionnaire the students asked/required to complete.
If this is the case, I would call the process 「教員評価」(kyouin-hyouka), which is teacher/instructor evaluation, and the questionnaire would be 「教員評価アンケート」(kyouin-hyouka ankeeto).
If you want to be specific, than you could add 学生対象の (gakusei-taishou-no).
I am not sure that all the kanji will go through the system, that's why I give the romaji versions as well.

On page 4 of the PDF file at the link below, you can find the following:
「本プロジェクトでは、先生方の授業に関する意識調査と学生対象の授業アンケートを実施するこ
とにより、その実態を様々な角度から客観的に把握、分析することで、授業改善、よりよい教授
法の構築の材料になればと考えています。」

They are talking about 「学生対象の授業アンケート」which could be what you looking for, however, this survey may be more general in content, and not specific to the individual teachers.

You can decide which one is best for you.
I hope this helps.
