Project STEM courses for any year are available through the end of the day on June 30 of that academic year. We highly recommend you download your gradebook before that date, as it will be very difficult to access after then!
After June 30, access is as follows below.
STUDENTS
Course platform and materials: no access after said date
Student forums: no access after said date
TEACHERS
Course platform and materials: read-only after said date so that teachers can still access course customizations, etc.
Teacher forums: access continues but help from Teaching Assistants is limited until mid-August.
