Constrained adaptive testing is reviewed as an instance of discrete maximization with the shadow-test approach delivering its solution. The approach may look counterintuitive in that it assumes sequential assembly of full test forms as its basic operation. But it always produces real-time solutions that are optimal and satisfy the set of specifications in effect for the test. Equally importantly, it can be used to run testing programs with different degrees of adaptation for the same set of specifications and/or as a tool to manage programs with simultaneous processes as adaptive item calibration, time management, and/or item-security monitoring.
