How does age adjustment affect normative interpretation?

• A. It enables fair comparison by stratifying norms by age.
• B. It eliminates age effects.
• C. It makes norms identical across ages.
• D. It eliminates percentile ranks.

Answer: (A)

Age adjustment in normative interpretation is about comparing a person’s score to a peer group of the same age. By stratifying norms by age, you create age-specific reference distributions, so the interpretation reflects where the individual stands relative to typical performance for their age. This makes comparisons fair across a wide age range because it accounts for developmental differences that come with growing older. Note that age adjustment doesn’t remove age effects from the measurement itself; it acknowledges them and uses them to shape the reference group. It also doesn’t make norms identical across ages—different ages will have different expected scores, which is why age-specific norms exist. Percentile ranks aren’t eliminated either—the ranking is determined within the appropriate age group, ensuring a meaningful comparison for someone at that age. So, age adjustment enables fair comparison by stratifying norms by age.
