The reliability and validity of a tailored testing procedure based on the simple logistic model was determined for an achievement test in statistics and measurement. The test was administered on a CRT terminal to students from graduate and undergraduate measurement courses. Equivalent form reliability over a one-week interval was found to be 0.595…

Three pyramidal adaptive tests and a conventional peaked test were constructed and administered by computer to two groups of students enrolled in undergraduate psychology courses. Six methods of scoring pyramidal tests were evaluated with respect to score distributions, stability, and the degree of relationship among scoring methods and between…

The measurement precision, efficiency, and validity of an adaptive test and four conventional listening tests designed to assess musical ability were compared. The conventional tests were the Seashore Tonal Memory Test and three tests (peaked, rectangular, and maximum discrimination) constructed from items in the 278-item adaptive test pool. The…

This study explores the test-retest consistency of computer adaptive tests of varying lengths. The testing model used was designed as a mastery model to determine whether an examinee's estimated ability level is above or below a pre-established criterion expressed in the metric (logits) of the calibrated item pool scale. The Rasch model was used…

The effects of review options (the opportunity for examinees to review and change answers) on the magnitude, reliability, efficiency, and concurrent validity of scores obtained from three types of computerized vocabulary tests (fixed item, adaptive, and self-adapted) were studied. Subjects were 97 college students at a large midwestern university…
