Online Class Evaluations:
Schedule: Online class evaluations will be available for students to
complete during the last 2 weeks of spring term: 8 a.m. April 13 through
8 a.m. April 27, Students will receive an email message directing them
to a website where they can login using their Unity ID and complete evaluations.
