Computer adaptive testing
In computer adaptive testing (CAT), the computer automatically scores responses and then adjusts subsequent questions according to the ability demonstrated by the test taker on the prior questions. This method provides a more accurate measurement of student achievement, particularly for high- and low-performing students.
With CAT, every student receives a unique set of test questions, reducing the need to test students on particular content simultaneously. This enables schools to group and assess students in a configuration that matches their specific capacity.
