  2. Select Security > Roles
  3. Click on the Schedule Manager role.
  4. Click the Members link on the left.
  5. To the right of the user that needs access to groups in Schedule Maker, click the Filter link.
  6. Under each Group Type, select the appropriate School Level.
  7. Click Save & Exit.

The user will need to completely log out of the system, then back in after these changes have been made to allow the access to update.
