Beta Testing


Beta testing provides controlled exposure of items in a new test bank to individuals of differing ability levels. The beta candidates are administered all items in a new test bank. After a sufficient number of beta test candidates complete the test, psychometricians analyze the beta test data. This is known as beta analysis. The range of candidate ability levels provides a basis for decisions to be made using the beta analysis results.

How is Beta Testing performed?

All items in the new test bank are administered to a group of beta candidates. This test administration is almost always done in a secure testing environment. The test owner (organization) chooses both the group of beta candidates and the beta test administration environment.
