No significant body of research examines writing achievement and the specific skills and knowledge in the writing domain for postsecondary (college) students in the U.S., even though many at-risk students lack the prerequisite writing skills required to persist in their education. This paper addresses this gap through a novel…

This paper highlights the need for a systematic, content aware, and theoretically-based approach to test design. The cognitive components approach is endorsed, and is applied to the development of a computerized perceptual speed test. Psychometric literature is reviewed and shows that: every major multi-factor theory includes a clerical/perceptual…

Response accuracy and response speed provide separate measures of performance. Psychometricians have tended to focus on accuracy with the goal of characterizing examinees on the basis of their ability to respond correctly to items from a given content domain. With the advent of computerized testing, response times can now be recorded unobtrusively…

Two experiments reproduced in a simulated computerized test-taking situation the effect of two of the main determinants in answering an item in a test: the difficulty of the item and the time available to answer it. A model is proposed for the time to respond or abandon an item and for the probability of abandoning it or answering it correctly. In…

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%…

Time limits on tests often prevent some examinees from finishing all of the items on the test; the extent of this effect has been called the "speededness" of the test. Traditional speededness indices focus on the number of unreached items. Other examinees in the same situation rapidly fill in answers in the hope of getting some of the…

The relationship between test item characteristics and testing time was studied for a computer-administered licensing examination. One objective of the study was to develop a model to predict testing time on the basis of known item characteristics. Response latencies (i.e., the amount of time taken by examinees to read, review, and answer items)…

Examinee response times from a computerized adaptive test taken by 204 examinees taking a certification examination were analyzed using a hierarchical linear model. Two equations were posed: a within-person model and a between-person model. Variance within persons was eight times greater than variance between persons. Several variables…

Differences in test performance on time-limited tests may be due in part to differential response-time rates between subgroups, rather than real differences in the knowledge, skills, or developed abilities of interest. With computer-administered tests, response times are available and may be used to address this issue. This study investigates…

The perspective of the examinee during the administration of a computerized adaptive test (CAT) is discussed, focusing on issues of test development. Item review is the first issue discussed. Virtually no CATs provide the opportunity for the examinee to go back and review, and possibly change, answers. There are arguments on either side of the…

In recent years, a controversy has arisen about the advisability of allowing examinees to review their test items and possibly change answers. Arguments for and against allowing item review are discussed, and issues that a test designer should consider when designing a Computerized Adaptive Test (CAT) are identified. Most CATs do not allow…

Specific questions addressed in this study include how time limits affect a test's construct and predictive validities, how time limits affect an examinee's time allocation and test performance, and whether the assumption about how examinees answer items is valid. Interactions involving an examinee's sex and age are studied. Two parallel forms of…

The advantages that computer adaptive testing offers over linear tests have been well documented. The Computer Adaptive Test (CAT) design is more efficient than the Linear test design as fewer items are needed to estimate an examinee's proficiency to a desired level of precision. In the ideal situation, a CAT will result in examinees answering…

An overview of the development of a computerized version of the Differential Aptitude Tests (DAT) is presented. It describes the previously existing printed version of the DAT, design of the computerized adaptive edition, calibration of the test items for use in the computerized version, and two field studies that compared the Adaptive and…

Possible causes of a 16-point mean score increase for the computer adaptive form of the College Level Academic Skills Test (CLAST) in reading over the paper-and-pencil test (PPT) in reading are examined. The adaptive form of the CLAST was used in a state-wide field test in which reading, writing, and computation scores for approximately 1,000…
