Summary:
J-CAT (Japanese-Computerized Adaptive Test) evaluates proficiency in Japanese as a foreign language via web. J-CAT consists of a item pool, test algorithm, and data base for recording the response patterns of test takers. Items are assigned discrimination parameters, difficulty parameters, and guessing parameters based on the Item Response Theory (IRT). The system delivers items matching the ability of test takers. This adaptive technique reduces testing time while keeping high reliability. Furthermore, IRT guarantees that the test is sample-independent and test-independent.
