Once a Progress Monitoring schedule has begun, you are unable to change the form level. The way around this is to release the students, and recreate a schedule being sure to edit the level.
NOTE: You only want to do this if you initially entered the student at the wrong level. You do not want to do this if you have already tested the student at the previous level in this group. To change the level that a student is being progress monitored at, you should make a new schedule at the new level.
Select the checkbox next to the Student Name, then select Edit Setup.
Edit the Monitoring Schedule for the selected student.
Update the Starting Form Number as needed. Select Next to toggle through other settings and update as needed. Select Save after all changes have been made.
