How does Prep-U compare to other computerized adaptive testing (CAT) engines?
Prep-U and computerized adaptive testing engines use a series of algorithms to present questions to users that are appropriate for their individual ability levels. The difference is that CAT systems measure mastery at a specific point, usually as a summative assessment at the end of a semester. Prep-U measures mastery throughout the semester and uses that information to create an adaptive training environment, helping students to recognize problem areas, focus their study time, and improve their skills through practice quizzes. Providing questions at the appropriate level throughout the semester enhances student engagement with the material—students are neither bored nor discouraged. The Prep-U engine continuously calibrates mastery levels so that students can see their progress. Prep-U’s main focus is not to measure mastery, but to improve it. For Prep-U, assessment is a means, not an end.
