First, you will want to make sure that Grading is enabled for all relevant groups. You can contact Support to verify if grading is enabled, and if it is not, Support will be able to enable it on your behalf.

Next, you need to make sure that the Grading Manager can see the new group type.
  1. Go to Core > Security > Roles
  2. Click Grading Manager
  3. Click Members
  4. Click Filter next to a member
  5. Mark all the groups he or she should see
  6. Click Save & Exit

Then you will then want to create a new Grade Translation for the group type, a new Grade Category, Grade Plan Groups and Grade Plans in the same way you did for Academics.
