CBT Item Authoring and Banking 4

Question 1

A candidate review panel (CRP) in the item development process is PRIMARILY responsible for:

Accepted Answer

Reviewing items for fairness, sensitivity, and absence of bias before banking

Answer

A CRP evaluates items for differential item functioning risks, stereotyping, and offensive content from the perspective of diverse candidate groups.

Question 2

Which IRT model parameter describes how well an item distinguishes between high- and low-ability candidates?

Accepted Answer

Discrimination parameter (a)

Answer

The 'a' parameter in IRT models represents item discrimination — the steepness of the item characteristic curve at the item's difficulty level.

Question 3

An item bank field called 'item status' would MOST commonly include which set of values?

Accepted Answer

Draft, Review, Approved, Active, Retired

Answer

Item status tracks an item's workflow stage from initial authoring through retirement, enabling version control and quality assurance.

Question 4

Which practice MOST effectively controls for 'testwise' cues in a selected-response item?

Accepted Answer

Randomizing option order and ensuring all options are similar in length and grammatical form

Answer

Uniform option length and randomized placement prevent candidates from using surface cues to identify the correct answer without knowing the content.

Question 5

What is the primary purpose of a 'pilot' or 'field test' section embedded in a live exam?

Accepted Answer

To gather psychometric statistics on new items without affecting candidates' scores

Answer

Embedded pilot items allow item banks to be populated with empirical difficulty and discrimination data before items are used for scoring.
