TTBJ is a collection of tests developed by the International Student Center at the University of Tsukuba. TTBJ is available for use according to the following two methods: as an individual test taker, as a group test taker.
Individual Test Takers
Individual test takers take the TTBJ in order to know their own Japanese proficiency. In the case, individuals must apply to take the test for themselves.
Group Test Proctors
Group test takers take the TTBJ in order to allow the test proctor (the teacher) to know the japanese proficiencies of multiple learners. In this case, the test proctor must apply to take the test for the group.
