Mary,
thanks for the response to my question, I used your information as a starting point. I created the second group for my teachers and gave them the permissions you suggested. I did also have to give them access to the permissions listed below as well. I believe I can scale back a few of these, but had to do it quick and dirty for now.
- moodle/user:update
- moodle/user:viewalldetails
- moodle/site:viewfullnames
- moodle/user:viewdetails
- mod/data:viewalluserpresets
