There are several ways to reset or clear a student's scores; you can:
Note: You cannot reset the scores for Lexile activities because allowing a student to retake the same exercise would lead to an invalid assessment of that student's reading level. For example, a student allowed to retake a reading-level exercise could through trial and error eventually answer every question correctly. The student would then be inappropriately matched with much more difficult readings. Because the student was not prepared for these higher-level readings, this would lead to invalid reading-level test outcomes and user frustration.
