The students that appear in your ASSISTments assignment report come directly from your LMS (Google Classroom or Canvas) account roster. If you want to make changes to your student roster, you have to do so within your LMS. Once you do so, follow these steps:
1. Create an assignment in ASSISTments and click 'Assign to Class'.
2. When you click assign, you will be taken to a pop-up with Assign-Time Options. Select your LMS (Google Classroom or Canvas), then click 'Import/Sync'.
3. You will then see a pop-up with options to Import or Synchronize. Click Synchronize.
4. Your rosters in ASSISTments will now be updated according to the most updated information available in your LMS.
