The user specifies true examinee ability, item pools, and item selection procedures, and the program outputs selected items with item responses and ability estimates.

This will continue until the item pool is exhausted unless a termination criterion is incorporated into the CAT.

Once the initial item pool was reduced, the second validation stage assessed how well items interrelated, and the psychometric properties of the test were determined.

Unidimensional approximations for a computerized test when the item pool and latent space are multidimensional (Research Report 97-5).

Separate models were used due to the high co-linearity between the skill and station scores, since both of these scores drew from the same item pool.

The international personality item pool and the future of public-domain personality measures.
