Age norms allow you to compare one student’s performance on the test with that of other students in the same age group.

The age norms for CogAT Form 7 extend from 4 years and 11 months to 21 years and 7 months. When Riverside Scoring Service scores CogAT, students are grouped by age in one-month intervals from 4 years and 11 months through 21 years and 7 months. When tests are hand scored, note that the CogAT Norms and Score Conversions Guide uses three-month intervals beginning with 5 years and 0 months and extending to 18+ years. Age groups are identified by the midpoint of the three-month span. For example, in age-normed tables in the CogAT Norms and Score Conversions Guide, the column headed 5-0 covers the age span of 4 years and 11 months, 5 years and 0 months, and 5 years and 1 month.
