Automatic item generation (AIG), or automated item generation, is a process linking psychometrics with computer programming. It uses a computer algorithm to automatically create test items that are the basic building blocks of a psychological test. The method was first described by John R. Bormuth [1] in the 1960s but was not developed until ...
In practical test construction, item analysis is an iterative process, and cannot be entirely automated. The psychometrician's judgement is required to determine whether the emerging set of items to be retained constitutes a satisfactory test of the target construct. [citation needed] The three criteria above do not always agree, and a balance ...
TAP (Test Analysis Program) is a free Windows program written in Delphi Pascal that performs test and item analyses based on classical test theory. TAP provides reports on examinee total scores, item statistics (e.g., item difficulty, item discrimination, point-biserial), options analyses, and other useful information.
In the realm of psychological testing and questionnaires, an individual task or question is referred to as a test Item or item. [6] [7] These items serve as fundamental components within questionnaire and psychological tests, often tied to a specific latent psychological construct (see operationalization). Each item produces a value, typically ...
In psychometrics, item response theory (IRT, also known as latent trait theory, strong true score theory, or modern mental test theory) is a paradigm for the design, analysis, and scoring of tests, questionnaires, and similar instruments measuring abilities, attitudes, or other variables.
An item bank Or Question Bank is a term for a repository of test items that belong to a testing program, as well as all information pertaining to those items. In most applications of testing and assessment , the items are of multiple choice format, but any format can be used.
The item–total correlation is the correlation between a scored item and the total test score. It is an item statistic used in psychometric analysis to diagnose assessment items that fail to indicate the underlying psychological trait so that they can be removed or revised.
Test-takers frequently complain about the inability to review. [9] Because of the sophistication, the development of a CAT has a number of prerequisites. [10] The large sample sizes (typically hundreds of examinees) required by IRT calibrations must be present. Items must be scorable in real time if a new item is to be selected instantaneously.
