In normative-developmental assessment, the performance is interpreted relative to which comparison group?

• A. A national sample.
• B. A single student's prior performance.
• C. A reference group of peers of similar age and gender.
• D. A comparison to teachers' norms.

Answer: (C)

In normative-developmental assessment, evidence is interpreted by comparing a child’s performance to a norm group. That group should be peers who are the same age and, when relevant, the same gender, so that the comparison reflects typical development for that specific age and gender. This age- and sex-matched reference allows us to place the child on a distribution of scores—such as percentile ranks or standard scores—showing whether they are at, below, or above the expected level for their peers. Using a single prior performance would be an ipsative comparison, which looks at change within the same individual rather than position relative to peers. While a national normative sample is a type of normed standard, the essential reference used in developmental norms is peers of the same age and gender. Comparing to teachers’ norms isn’t standard practice.
