|Keywords||CAT, CAT evolution, test content|
All testing involves a balance between measurement precision and content considerations. CAT item-selection algorithms have evolved to accommodate content considerations. Reviews CAT evolution including: Original/”Pure” adaptive exams, Constrained CAT, Weighted-deviations method, Shadow-Test Approach, Testlets instead of fully adapted tests, Administration of one item may preclude the administration of other item(s), and item relationships.
