CASSYS evaluates the listening/reading comprehension skills, the knowledge of grammar and vocabulary, according to the six competence levels of the CEFR scale. The system is based on an item bank continuously upgraded, so that the user can repeat the test several times without answering the same questions.

Once completed the test, the user is shown the score and the corresponding CEFR level. The test results are registered on the learning platform and can be consulted by the HR-manager and the instructors.
