Hi Dave,
I have used questionnaires for each course I've taught. I normally use the feedback activity. You can include ratings for all teachers in one single feedback or create one feedback activity for each teacher. You can also configure the access rights so that teacher cannot access the questionnaire. Since you can export the results as a file, you can edit the file, include only the responses about a specific trainer and create several reports, one for each teacher.
