In which circumstances, would you recommend Computerized Adaptive Testing to be used?

Correct Answer

verifed

There would need to be a large volume of testing to justify the expense of CAT, and so an organization that tests only a few people on an irregular basis might not be a good candidate for CAT. In addition, without a large number of people taking the test, it will be hard to get a large enough sample to estimate parameters with accuracy. Second, if there is a wide range of test takers who will be taking the test it may be important to use a CAT so that individual tests can be tailored to the diverse range of test takers. Third, if test taker time needs to be minimized, the efficiency of CAT will be viewed as an important asset. Finally, if test security is paramount, the increased security due to CAT can be a big asset.
