Abstract:
The majority of studies focusing on enhancing item bank security and measurement efficiency in
computer adaptive tests (CATs) have featured large item banks consisting of thousands of items. For
many practitioners of high-stakes tests, CATs are a viable alternative to static forms, but inadequate
resources exist for developing expansive item libraries. Practitioners may need to consider alternative
solutions for maintaining CAT integrity and proficiency. This study documents the effects of changing the
size of minimum eligible item pools for selection on test length, maximum exposure frequency, and total
item usage across four operational item banks of various size and quality.
