Elements of Adaptive Testing

Abstract

The arrival of the computer in educational and psychological testing has led to the current popularity of adaptive testing--a testing format in which the computer uses statistical information about the test items to automatically adapt their selection to a real-time update of the test takers ability estimate. This book covers such key features of adaptive testing as item selection and ability estimation, adaptive testing with multidimensional abilities, sequencing adaptive test batteries, multistage adaptive testing, item-pool design and maintenance, estimation of item and item-family parameters, item and person fit, as well as adaptive mastery and classification testing. It also shows how these features are used in the daily operations of several large-scale adaptive testing programs.
