The General Computer Adaptive Test (CAT) of the Graduate Record Examinations (GRE) includes three operational sections that are separately timed and scored. A "no score" is reported if the examinee answers fewer than 80% of the items or if the examinee does not answer all of the items and leaves the section before time expires. The 80%…

A study was conducted to evaluate the effects of choice of item response theory (IRT) model, parameter calibration group, starting ability estimate, and stopping criterion on the conversion of an 80-item vocabulary test to computer adaptive format. Three parameter calibration groups were tested: (1) a group of 1,000 high school seniors, (2) a…

The use of indices and statistics based on nonlinear factor analysis (NLFA) has become increasingly popular as a means of assessing the dimensionality of an item response matrix. Although the indices and statistics currently available to the practitioner have been shown to be useful and accurate in many testing situations, few studies have…

Technology has provided the public with the ability to steal the contents of multiple examinations in a short time period and at minimal cost. No examination is safe from compromise, and the only variable is the extent and sophistication used to bring about the compromise or theft. With the easy availability of micro-video equipment, audio…

In self-adapted testing (SAT), examinees select the difficulty level of items administered. This study investigated three variations of prior information provided when taking an SAT: (1) no information (examinees selected item difficulty levels without prior information); (2) view (examinees inspected a typical item from each difficulty level…

The use of paper and pencil, videotape recordings, and microcomputers in student testing provide three very different views of student achievement. Paper and pencil tests can record how students compose tests and documents, and how they critique documents or performances. Video recordings can record how students explain ideas, answer questions,…

This simulation study involved the design of two two-stage tests in which the routing tests and the second-stage measurement testlets took the form of a multidimensional knapsack problem with prespecified target informations and constraints to be enumerated using the algorithm of E. Balas. Two conventional tests of similar length to the two-stage…

Assessment of Baseline Curriculum (ABC Tests) is a locally developed objectives-referenced assessment system that matches the Dallas Independent School System's Baseline Curriculum. Designed for instructional use and not for accountability, a major purpose of the ABC Test is to measure student attainment of objectives in the Mathematics and…

A pilot study of a computerized adaptive test of mathematics achievement was conducted in May and June 1989 in selected schools of the San Diego Unified School District. The study evaluated the usefulness of the test for determining eligibility for Chapter 1 programs in mathematics. The test was a prototype battery of three adaptive tests: (1)…

This paper presents the results of a questionnaire sent to 211 Measurement Services Association members. Sixty-four centers responded. The main purpose of the questionnaire was to find out what hardware and software are used by testing centers throughout the country. Results indicate that 52 institutions use mainframe computers, 50 use…

The Computerized Adaptive Testing (CAT) project is a joint Armed Services coordinated effort to develop and evaluate a system for automated, adaptive administration of the Armed Services Vocational Aptitude Battery (ASVAB). The CAT is a system for administering personnel tests that differs from conventional test administration in two major…

Computerized adaptive testing (CAT) offers the opportunity to replace paper-and-pencil aptitude tests such as the Armed Services Vocational Aptitude Battery with shorter, more accurate, and more secure computer-administered tests. Its potential advantages need to be verified by experimental administration of automated tests to military recruit…

The resurgence of testing and the significance of this trend to learning assistance facilitators and developmental educators are discussed. This increase in testing, particularly as it manifests itself on college and university campuses, reflects a shift of emphasis in testing, from measuring aptitude to measuring the effect of instruction.…

The United States Armed Services are planning to introduce computerized adaptive testing (CAT) into the Armed Services Vocational Aptitude Battery (ASVAB), which is a major part of the present personnel assessment procedures. Adaptive testing will improve efficiency greatly by assessing each candidate's answers as the test progresses and posing…

Implementation of an adaptive achievement test for teaching signed-numbers operations to junior high students is described. A computer program capable of finding 240 basic errors in signed-number computations was written on the PLATO system and used for analyzing a 64-item conventional test, as well as an adaptive test of addition problems. The…
