Tutoring Help

RMMS is offering after school tutoring beginning Tuesday, September 13th.  Tutoring sessions will be offered on Tuesdays and Thursdays from 2:45-3:45 in the library.  Both student and adult AVID tutors will be available to support student academics in each of the subject areas, or students can attend in order to have a quiet place to complete homework.  All students are welcome and must have a parent signature on our tutoring contract in order to attend.  Students can pick up a copy of the contract in the front office.

Click on the link and follow the directions to report an incident directly to Ruth Musser Middle School.
