The Japanese-Language Proficiency Test or JLPT, is a standardized criterion-referenced test to evaluate and certify Japanese language proficiency for non-native speakers, covering language knowledge, reading ability, and listening ability. The test is held twice a year in Japan and selected countries (on the first Sunday of July and December), and once a year in other regions (either on the first Sunday of December or July depending on region). The JLPT is conducted by the Japan Foundation for tests overseas (with cooperation of local host institutions), and Japan Educational Exchanges and Services for tests in Japan.
The JLPT consists of five independent levels of certification, with 5 the lowest and 1 the highest. Until 2009, the test had four levels of certification. JLPT certificates do not expire or become invalid over time.
