What does Computerized Adaptive Testing (CAT) use to determine the next question for an examinee?

Computerized Adaptive Testing (CAT) utilizes the answers provided by the examinee to previous questions to determine the next question that will be presented. This approach allows the test to adapt to the individual's skill level in real-time. When a test-taker answers a question correctly, the system will typically present a more challenging question next. Conversely, if a question is answered incorrectly, the subsequent question will likely be less difficult. This adaptive mechanism helps in accurately measuring the examinee's ability and knowledge level, ensuring that the assessment is both efficient and tailored to individual performance.

The other options involve elements that do not serve as the primary method for selecting subsequent questions in a CAT format. For instance, while the time taken to answer questions might provide insights into a test-taker's confidence or speed, it does not directly influence which question comes next. Similarly, a test-taker's previous learning history could inform their abilities but isn't used in the immediate, adaptive response mechanism of CAT. Random selection of questions does not apply to CAT, as the system is designed to customize the experience based on prior responses rather than use a random approach.
