An adaptive testing method is presented that controls the speededness of a test using predictions of the test takers' response times on the candidate items in the pool. Two different types of predictions are investigated: posterior predictions given the actual response times on the items already administered and posterior predictions that use the…

Multilinear formula scoring (MFS) is reviewed, with emphasis on estimating option characteristic curves (OCSs). MFS was used to estimate OCSs for the arithmetic reasoning subtest of the Armed Services Vocational Aptitude Battery for 2,978 examinees. A second analysis obtained OCSs for simulated data. The use of MFS is discussed. (SLD)

Equating a new standard test to an old reference test is considered when samples for equating are not randomly selected from the target population of test takers, identifying two problems from equating from biased samples. An empirical example with data from the Armed Services Vocational Aptitude Battery illustrates the approach. (SLD)

This paper addresses practical Army problems in reading assessment from a theory base reflecting the most recent research on reading comprehension. Military and occupational research shows that reading proficiency is related to job performance. Reading assessment is a key issue in the Army due to changes in the reading ability levels of the Army…

The purpose of this resarch was to develop a model of verbal information processing for use in subsequent analyses of the construct and predictive validity of the current Department of Defense military selection and classification battery, the Armed Services Vocational Aptitude Battery (ASVAB) 8/9/10. The theory and research methods of selected…

Presented is an investigation of the item and factor characteristics which make up Forms 8, 9, and 10 of the Armed Services Vocational Aptitude Battery (ASVAB). Data on the ASVAB forms were collected from mulitary enlistment applications at 20 Armed Forces Examining and Entrance Stations. Item and factor analyses were conducted on samples equated…

The goal of this research was to predict from a recruit's responses to the Armed Services Vocational Aptitude Battery (ASVAB) items whether the recruit would pass the Armed Forces Qualification Test (AFQT). The data consisted of the responses (correct/incorrect) of 1,020 Navy recruits to 200 items of the ASVAB together with the scores of these…

This report describes technical plans and progress during the second year (Fiscal Year 1984) of work on the U.S. Army's Project A: "Improving the Selection, Classification, and Utilization of Army Enlisted Personnel." Project A is a long-range research program developed by the Army Research Institute for the Behavioral and Social…

ASCAL is a microcomputer-based program for calibrating items according to the three-parameter logistic model of item response theory. It uses a modified multivariate Newton-Raphson procedure for estimating item parameters. This study evaluated this procedure using Monte Carlo Simulation Techniques. The current version of ASCAL was then compared to…

Six new forms of Armed Services Vocational Aptitude Battery (ASVAB) were developed. These new forms were equated to a standard reference test, ASVAB 8a, using normative data based on a 1980 weighted probability sample of American youth, ages 18-23. Equating allows the services to report the distributions of examinee ability on a common metric or…
