Although your tier thresholds default to our recommended percentages, you can change them to fit your needs with just a few steps.
You can access the Tier Thresholds screen by clicking Skills from the menu on the left. Next, click on Tier Thresholds.
From the Tier Thresholds screen, you can set which percentage of students are automatically assigned to each tier. Simply enter which percentage of students you'd like assigned to each tier level and click Save Changes when you finish.
