Computerized Adaptive Testing:

Smarter, Shorter Exams

Computerized Adaptive Testing (CAT) is a modern AI-based approach to delivering exams that are shorter, more engaging, and more secure. We make it easy to convert existing exams to an adaptive format, or empower you to do so on your own.

Modern Psychometrics, Simplified

There’s no need to be a machine learning expert or write complex code – our easy-to-use interface lets you specify the CAT options that you want to use. Just import your item response theory parameters, set up the test options, and you can start delivering adaptive tests! What is a CAT? It is a test that adapts uniquely to each examinee. If you get an item right, your next item is harder, and vice versa. But this isn’t based on subjective Grade ratings or anything; it is all driven by psychometric models known as item response theory.

Improve reliability, validity, and security

Computerized adaptive testing is scientifically-developed with a host of well-known benefits. Exams are shorter, which can drastically reduce delivery costs and time away from instruction. Because each examinee receives a unique test, it is far more secure than a single linear exam. Examinees stay more engaged because they receive a test that is perfectly tailored for them. And that’s just the start!

Adaptive testing improves security

Because each examinee receives a unique test, it is far more secure than a single linear exam, or even a bundle of linear forms. Moreover, if they retake the test, they will likely see different items. This is especially useful in educational formative assessment, where students might test every 3 months; because they have learned a lot (hopefully), they will have progressed onto new content. Adaptive testing will quickly determine their appropriate level of content and adjust the test to each student.
