Computerized Adaptive Testing (CAT) is a modern approach to assessments that utilizes computer algorithms to dynamically adapt the difficulty of test questions based on the test taker's performance.
CAT offers several benefits over traditional testing methods, such as reducing test time and increasing the accuracy of the test scores. However, creating and implementing a CAT system can be challenging for educators and researchers without the right tools. That's whereCAToolkit comes in.

What Is CAToolkit?

CAToolkit is an innovative software platform developed by the University of Hertfordshire's Adaptive Measurement and Assessment Group. It is designed to provide an accessible and user-friendly solution for researchers and educators to develop, administer and score CAT assessments.
The platform is highly customizable, allowing users to tailor assessments to their specific needs, and it supports a wide range of item types, including multiple-choice, constructed-response, and performance-based items.

How Does CAToolkit Work?

CAToolkit uses item response theory (IRT) algorithms to generate a sequence of test items that best fit the test taker's ability level.
As the test progresses, the algorithm continually adjusts the difficulty level of the next question based on the test taker's responses to previous questions. This approach ensures that the test is tailored to the individual's ability level, which increases the accuracy and efficiency of the test.
