The MAP Growth test is a computer adaptive test. What does this mean?
A computer-adaptive test (CAT) is a method for administering tests that adapt to a student's ability level. The difficulty of the test tailors itself to the student's achievement level. The first time a student takes a computer-adaptive test, the pool of available items is searched for an item based on the student's current achievement estimate. When a student responds correctly, they receive a more difficult item. Similarly, incorrect responses are followed by easier items. After only a few questions, the item difficulties are close to a student's true achievement level and a reasonable estimate can be reported, in the form of a RIT score. See What is the RIT scale? for more information.
What are the advantages of computer adaptive testing?
- You can administer tests on demand and scores are available immediately.
- Tests are individually paced, potentially reducing one source of test anxiety.
- Test security is increased because there are no hard copy test booklets to be compromised.
- Students spend less time testing, because significantly fewer items are needed to provide uniformly precise scores.
- We can provide accurate scores across a wide range of abilities. Traditional tests are usually most accurate for average students.
