Why does a test ask for my birth date?

Some tests use age-normed scoring, which means your results are compared against people in your specific age group. To calculate accurate percentiles for these tests, we need your date of birth.

If your profile doesn't have a birth date set, you'll be prompted to add it before starting an age-normed test.

You can add or update your date of birth at any time in Dashboard > Settings > Profile.

Your date of birth is never displayed publicly or shared with other users. It is used only for scoring purposes.
