CODESP Test Validation and Reliability

Question 1

Which type of validity evidence examines whether test scores correlate with an external criterion measured at the same time?

Accepted Answer

Concurrent validity

Answer

Concurrent validity is established when test scores correlate with a criterion measure collected simultaneously.

Question 2

A reliability coefficient of 0.50 for a selection test would generally be considered:

Accepted Answer

Too low for most selection purposes

Answer

A reliability coefficient of 0.50 is generally considered too low for employment selection tests, which typically require 0.70 or higher.

Question 3

What does the standard error of measurement (SEM) primarily tell us?

Accepted Answer

The expected variation in an individual's scores across repeated administrations

Answer

SEM estimates how much an individual's observed score is likely to vary if the test were administered multiple times.

Question 4

When a test is used to predict future job performance measured six months after hiring, this is an example of:

Accepted Answer

Predictive validity

Answer

Predictive validity involves collecting criterion data after a time delay following test administration.

Question 5

Which reliability method requires only a single test administration?

Accepted Answer

Internal consistency reliability

Answer

Internal consistency methods (e.g., Cronbach's alpha, KR-20) assess reliability using data from a single test administration.
