A number of testing programs have implemented CAT in the last several years. Following is an updated list of current CAT testing programs. We will be adding more programs regularly as they become available. If you are involved in a testing program that has implemented CAT, please send details about it to us so that it can be added here.

Adaptive English Proficiency Test for Web (ADEPT). CALEAP-Web employs a computer-based adaptative test, Adaptive English Proficiency Test for Web (ADEPT), with questions selected on the basis of IRT. Calibration of the items is carried out with the algorithm CBAT-2 (Huang, 1996), a self-adaptive testing which calibrates the parameters of the items during the test. This is integrated into the Computer-Aided Task Environment for Scientific English (CATESE) to train the students about conventions of the scientific texts.

American Institute of Certified Public Accountants (AICPA) put into operation a computer-based testing program for the Uniform CPA Examination, which is used in licensing CPAs in the U.S. The CPA Exam uses a multi-stage model, which includes adaptive, content-balanced testlets. In this model, branching decisions are made after completion of each 20- to 25-item testlet. Three testlets are administered, followed by two non-adaptive accounting simulations. The model, though not providing optimal measurement, allows candidates to review their answers within testlets and simulations. Also, the model allows for substantial quality controls and ensures content balance before the exam is released into the field. For further information see

Four CATs are designed for primary education, including a test of basic arithmetical skills and a test of language (vocabulary and listening) constructed for ages 4-6. Some tests are part of screening instruments to detect dyslexia and early literacy. There are also two tests for basic skills in arithmetic/mathematics, one for screening in the first year of teacher training in the Netherlands and one for screening nurse practitioners.
