Question 1

Which type of validity evidence examines whether a test's internal structure matches its theoretical constructs?

Accepted Answer

Internal structure validity

Answer

Internal structure validity evidence (part of construct validity) examines whether item relationships and factor structure align with the theoretical model.

Question 2

A selection test with a 0.40 criterion-related validity coefficient is used with a base rate of 50% and a selection ratio of 20%. Using the Taylor-Russell tables, what effect does lowering the selection ratio have on the success ratio?

Accepted Answer

It increases the success ratio

Answer

Lower selection ratios (hiring fewer, more selective) increase the success ratio because you are selecting only top scorers from a larger pool.

Question 3

The Angoff method, Bookmark method, and Contrasting Groups method are all approaches to:

Accepted Answer

Setting passing scores (cut scores)

Answer

The Angoff, Bookmark, and Contrasting Groups methods are standard-setting procedures used to establish defensible cut scores on employment or credentialing tests.

Question 4

Which phenomenon occurs when candidates' scores on a selection instrument improve substantially upon retesting, threatening the validity of the instrument?

Accepted Answer

Coaching and practice effects

Answer

Coaching and practice effects occur when retesting leads to score gains unrelated to the underlying construct, threatening test validity for repeat test-takers.

Question 5

In Item Response Theory (IRT), the 'b' parameter represents:

Accepted Answer

Item difficulty (location)

Answer

In IRT, the b parameter is the item difficulty or location parameter, indicating the trait level at which the probability of a correct response is 0.50 (in 1PL/2PL models).
