The Science Behind GELPS: Computer-Adaptive Testing Explained

August 07, 2024 · GELPS Blog

GELPS uses computer-adaptive testing (CAT) technology, which adjusts the difficulty of questions in real time based on your performance. If you answer correctly, the next question is slightly harder; if you struggle, the next question is easier. This approach provides a precise measurement of your English proficiency in about 60 minutes, compared to the 3+ hours required by traditional tests. CAT also enhances security by ensuring no two test-takers receive the same set of questions.
