Which statement correctly contrasts standard-based and norm-referenced assessments in SPED?

• A. Standard-based assessments compare performance to a normative group.
• B. Standard-based assesses performance against grade-level standards; norm-referenced compares performance to a normative group.
• C. Both types are equally influenced by the normative group.
• D. Norm-referenced assessments measure growth over time only.

Answer: (B)

When we look at how scores are interpreted, the key difference is in what the score is meant to show. Standard-based (criterion-referenced) assessments measure whether a student has met specific grade-level standards or learning targets. They provide an absolute measure of mastery—can the student do the defined skills?—and are used to guide instruction and track progress toward those standards. Norm-referenced assessments, on the other hand, compare a student's performance to a normative group, yielding relative rankings like percentile ranks or standard scores. They show how the student stacks up against peers, not whether they have mastered particular standards.

This contrast is why the correct statement is that standard-based assessments evaluate performance against grade-level standards, while norm-referenced assessments compare performance to a normative group. The idea that standard-based assessments compare to a normative group, or that both types are equally influenced by the normative group, or that norm-referenced assessments measure growth over time only, would mischaracterize how these tools are designed and used.
