The document discusses the Japanese-Language Proficiency Test (JLPT), which evaluates and certifies the Japanese proficiency of non-native speakers. It notes that the JLPT began in 1984 with 7,000 examinees but grew significantly to 770,000 examinees worldwide by 2009, making it the largest Japanese language test. The JLPT aims to ensure its continued relevance through revisions informed by Japanese pedagogy and testing theory. It tests communicative competence through vocabulary, grammar, and practical application. Examinees choose between five levels from N5 (easiest) to N1 (most difficult).
