PC Score Reporting and Interpretation 3

Question 1

What is the primary purpose of score equating in large-scale testing programs?

Accepted Answer

To adjust scores so that they are comparable across different test forms of equal difficulty

Answer

Score equating adjusts for differences in difficulty between alternate test forms so that scores from different forms can be used interchangeably.

Question 2

What does a 'derived score' refer to in psychometric score reporting?

Accepted Answer

Any score that results from transforming or converting a raw score

Answer

A derived score is any score produced by mathematically transforming raw scores, including percentile ranks, standard scores, stanines, and grade equivalents.

Question 3

Disaggregated score reporting involves presenting test results broken down by subgroups. What is the primary benefit of this practice?

Accepted Answer

It allows identification of performance gaps across demographic or instructional subgroups

Answer

Disaggregated reporting reveals differential performance patterns among subgroups, enabling targeted interventions to address achievement gaps.

Question 4

In score linking, what does an 'anchor test' design accomplish?

Accepted Answer

It provides a common set of items used across forms to enable score comparisons

Answer

An anchor test (also called common items) is a set of identical items embedded in different test forms to establish a statistical link for equating scores across forms.

Question 5

A composite score is constructed by combining subscale scores. Which factor is most important to verify before creating a composite?

Accepted Answer

That the subscales measure conceptually related constructs and have adequate reliability

Answer

A meaningful composite requires subscales that share a coherent construct and sufficient reliability; combining unrelated or unreliable subscales produces an uninterpretable composite.
