Placement and practice tests can be used to assess and place students in appropriate levels. The Oxford Online Placement Test (OOPT) is a computer-adaptive test that is short, comprehensive, reliable, clear, and flexible. It assesses students' use of English and listening skills. The test draws from several sources to design grammar, vocabulary, and meaning questions. Test results provide students' scores on different skills and an estimated CEFR level for placement or tracking progress. Teachers can assign tests through an online system for practice, homework, or under exam conditions.
