The goal of this project was to develop an inexpensive, self-contained system of hardware and software to support the development, administration, and evaluation of computerized adaptive tests. Toward that goal, commercial hardware was selected and a comprehensive software called the MicroCAT Testing System was developed. The MicroCAT system was…

The 104 instruments in this bibliography contain collections of test items or learning objectives with accompanying sample items for use in the construction of tests. In some cases, actual test construction is performed by the publisher. Subjects covered include: reading, mathematics, sciences, languages, social sciences, and the arts. Some item…

This study utilized a straightforward system of crediting successes and assigning failures to items not administered during computerized adaptive testing (CAT) to determine if the data yielded by CAT could be used to monitor item calibrations over time. (Author/LMO)

Findings of studies examining the effects of presentation media on item characteristics are reviewed. The effect of medium of presentation independent of adaptive methodology in computer-assisted testing was studied through tests of 763 Marine trainees. Conditions necessary for score equivalence between item presentation media are described. (SLD)

The present monte carlo simulation study was designed to examine the effects of multidimensionality during the administration of computerized adaptive testing (CAT). It was assumed that multidimensionality existed in the individuals to whom test items were being administered, i.e., that the correct or incorrect responses given by an individual…

A study was conducted to validate the Army's Computerized Adaptive Screening Test (CAST), using data from 2,240 applicants from 60 army recruiting stations across the nation. CAST is a computer-assisted adaptive test used to predict performance on the Armed Forces Qualification Test (AFQT). AFQT scores are computed by adding four subtest scores of…

A computerized testing system was implemented in conjunction with the Radar Technician Training Course at the Naval Training Center, Great Lakes, Illinois. The feasibility of the system and students' attitudes toward it were examined. The system, a multilevel, microprocessor-based computer network, administered tests in a sequential, fixed length…

To date, the majority of computerized adaptive testing (CAT) systems for achievement and aptitude testing have been based on the dichotomous item response models. However, current research with polychotomous model-based CATs is yielding promising results. This study extends previous work on nominal response model-based CAT (NR CAT) and compares…

A computerized adaptive testing version of the Armed Services Vocational Aptitude Battery (CAT-ASVAB) is being developed to test ten areas of vocational aptitude. Development of the CAT-ASVAB is based upon the use of item banks, testing and scoring procedures, assessment of test reliability and test validity, a technical manual, and the…

A computerized testing system was installed on an experimental basis at the Basic Electricity and Electronics School of the Naval Training Center in San Diego. The system consisted of a network of IBM Personal Computers running a slightly modified version of the commercially available MicroCAT Testing System. It was configured to fit transparently…

A computerized adaptive testing model was assessed in a technical training system. The model, a modification of Lord's flexilevel paradigm, consisted of: the sequencing of test items in a difficulty hierarchy, adaptive entry of students into the test at a difficulty level appropriate to their predicted score, and systematic movement of students…

A computerized adaptive testing model was applied to a hierarchically arranged series of subtests within the instructional context of a technical education system. The model was a modification of Lord's flexilevel paradigm; however, it did not allow for individualized entry. Two achievement tests, each divided into five hierarchically related…

An adaptive testing strategy is described for achievement tests covering multiple content areas. The strategy combines adaptive item selection both within and between the subtests in the multiple-subtest battery. A real-data simulation was conducted to compare the results from adaptive testing and from conventional testing, in terms of test…

The report describes the process and procedures undertaken to recommend topics for a California community college (Oxnard College) faculty resource guide, intended to facilitate test-taking by students with disabilities. An expert panel composed of college administrators, special educators, other faculty members, and community professionals…

During a three-year project (1977-1980) on computerized adaptive achievement testing, item characteristic curve theory (ICC) and adaptive testing strategies designed almost exclusively for ability testing were applied to achievement testing. Adaptive techniques substantially reduced test length without reducing quality, when applied to three…
