摘要： The present invention allows a language learning platform to calculate a user's overall language skill. This may be performed as a standalone test or before, during and/or after a language course. The language learning platform may perform a Pre-CAT process, a CAT process, a stage 2—fixed form process and a scoring and reporting process. The Pre-CAT process is designed to quickly get an initial estimate of the user's overall language skill. The CAT processes improves on the accuracy of the Pre-CAT process, preferably until the conditional standard error of measurement for the user's overall language skill is less than a predetermined number. The stage 2—fixed form process may use the user's overall language skill to select speaking, listening and writing assessment items of an appropriate difficulty for the user. The language learning platform may score the responses of the user, present the measured user's overall language skill to the user and save the user's overall language skill in a database for use in future tests.
