CASAS Test Design & Development 3

Question 1

CASAS assessments are best classified as which type of test?

Accepted Answer

Criterion-referenced tests that measure performance against defined standards

Answer

CASAS assessments are criterion-referenced, meaning scores indicate mastery of specific competencies rather than rank among peers.

Question 2

Which type of validity evidence is most directly supported by having subject matter experts review CASAS items against the competency framework?

Accepted Answer

Content validity

Answer

Content validity is established when experts confirm that test items adequately represent the full range of skills and competencies the test is designed to measure.

Question 3

The standard error of measurement (SEM) is used in CASAS score interpretation to:

Accepted Answer

Estimate the range in which a test-taker's true score likely falls

Answer

SEM quantifies measurement error, allowing educators to construct a confidence interval around an observed score to approximate the test-taker's true ability.

Question 4

How does CASAS ensure score comparability across its multiple equivalent test forms?

Accepted Answer

Through an item bank with IRT-based scaled scores

Answer

CASAS maintains a calibrated item bank using IRT, so scaled scores are comparable regardless of which form a test-taker completes.

Question 5

Test-retest reliability refers to:

Accepted Answer

The consistency of scores when the same group takes the same test at two points in time

Answer

Test-retest reliability measures score stability over time by correlating results from two administrations of the same instrument to the same group.
