The STAMP test is a four-skill (reading, writing, listening, and speaking) proficiency test that uses content "based on real-world, everyday situations written by native speakers that determines levels of proficiency defined by the American Council on the Teaching of Foreign Languages." I received the following scores on the Japanese STAMP test:
Reading: 8/9 (Advanced Mid)
Writing: 8/8 (Advanced Mid)
Listening: 7/9 (Advanced Low)
Speaking: 7/8 (Advanced Low)
