The Japanese Language Proficiency Test (JLPT) is a test that all Japanese learners must take to prove that they can speak and understand the language. JLPT has three sections: listening, reading, and writing. In order to take the test, you must be at least 16 years old and must have a high school education or be able to prove that you have a high school education in Japanese.

You will have to complete a number of questions, and if you get a passing grade, you will be able to move onto the next section. Each section has a different level of difficulty, and if you get a good score, you will be able to move onto the next section.
