Age-Equivalent Scores

Interpretation of the age-equivalent score is similar to that ofthe grade-equivalent score. A raw score corresponds to a chronological age. Ateacher can use a norms table to determine such scores. A portion of a normstable would look something like this:

--Chronological age--
Raw 6.0 6.6 7.07.68.0
Score-Age-equivalent score-
206.7 6.46.26.05.7
216.86.56.36.15.8
226.96.66.46.25.9
236.106.76.56.35.10

Therefore, a student, age 7.6 (7 years, 6 months), who gets a raw score of 20,has an age-equivalent score of 6.0 (6 years, 0 months). If a student, age 6.0,also gets a raw score of 20, his age-equivalent score is 6.7. The 6.0-year olddid better for his age group than the 7.6-year old, but the 6.0-year oldprobably does not know as much as the older child. Like the grade-equivalentscore, the age-equivalent score should only be used as a relative measure ofassessment.
