Computerized adaptive testing (CAT) is a form of computer-based test that adapts to the examinee's ability level. For this reason, it has also been called tailored other words, it is a form of computer-administered test in which the next item or set of items selected to be administered depends on the correctness of the test taker's responses to the most recent items administered.

Exposure control research with polytomous item pools has determined that randomization procedures can be very effective for controlling test security in computerized adaptive testing (CAT). The current study investigated the performance of four procedures for controlling item exposure in a CAT under the partial credit model.
Computerized adaptive testing (CAT) presents a tradeoff problem between increasing measurement accuracy and decreasing item exposure in an item pool. To address this difficulty, we propose a new CAT that partitions an item pool to numerous uniform item groups using a maximum clique algorithm and then selects the optimum item with the highest Cited by: 1.

In computerized adaptive testing, testing continues until-the examinee fails a specific number of items in a row-a predetermined level of measurement accuracy is achieved-the examinee is administered the most difficult item-none of the above.

Computerized Adaptive Testing: 4/5(1). Computerized tests may replace paper-and-pencil tests in some instances. With computerized tests, each student's ability level can be estimated DURING the testing process and items can be tailored to this estimate of ability.
Consequently, students can take different versions of the same test. These tests are called computerized adaptive tests. Betz, N. New types of information and psychological implications. In D.

One of the main goals of computerized adaptive testing (CAT) is to obtain precise ability estimates with a small number of items. To achieve this goal, items are selected specifically for each examinee from a large bank.
Computer-adaptive tests are designed to adjust their level of difficulty—based on the responses provided—to match the knowledge and ability of a test taker. If a student gives a wrong answer, the computer follows up with an easier question; if the student.
A complete list of CAT research has the term "computer-adaptive" used in titles only 43 times - "computerized adaptive" is used approximately times. And it's impossible to argue with a 'sample' of that size.
Computerized adaptive testing became the accepted terminology when Reckase's use of "tailored testing" died out. Computerized adaptive testing (CAT) is a form of computer-based test that adapts to the examinee's ability level.
For this reason, it has also been called tailored testing. This book contains most of what you need to understand how computerized adaptive tests (CAT) do what they do. It is a good complement to the seminal book on Item Response Theory (IRT) by Wainer's colleague, Frederic Lord (Applications of Item Response Theory to Practical Testing Problems).Cited by: With a general aim to address needs in formative assessments, this dissertation aims to achieve three objectives: (1) to introduce two new item selection indices for cognitive diagnosis computerized adaptive testing (CD-CAT); (2) to control item exposure rates in CD-CAT; and (3) to propose an alternative CD-CAT administration : Mehmet Kaplan.
in operational computerized adaptive testing (CAT) systems. These exposure problems might result in item compromise, or point at a waste of investments.
The exposure control problem can be viewed as a test assembly problem with multiple objectives. Information in the test has to be maximized, item compromise has to be minimized, and pool usage. A client of American College Testing, Inc. (ACT) decided to implement a computer-based testing program to replace their paper-pencil format for professional certification.
This paper reports on the results of the developed test after 1 year's use, especially as the results relate to test security issues.

SimulCAT can generate reports on item pool usage and CAT administrations. For more advanced research, SimulCAT provides users with options to input differential item functioning (DIF) or item parameter drift (IPD) information as well as preexisting item exposure data.
