The following export can be used to create the CSV file necessary for the manual upload of student groups:
If you want to use your ADA grade level sections as groups, use the default parameters:
If you want custom groups, you can create an 'Activity' course and sections and enroll students in the classes/groups as needed.
For example: Add a new 'CAASPP Testing Group' activity.
Then, when you run the export, you would use the Course Filter parameter and set the Section Period to '* Select All'.
Once you have the CSV file, you can manually upload it to CERS on their Manage Student Groups (ets.org) page.
