In Japan, the test is administered by the Japan Educational Exchanges and Services (JEES) (財団法人 日本国際教育支援協会 zaidan hōjin nihon kokusai kyōiku shien kyōkai), while the Japan Foundation (独立行政法人 国際交流基金 dokuritsu gyōsei hōjin kokusai kōryū kikin) administers overseas tests. The JLPT is offered in approximately 85 countries. Also ask about the application period and application fee as they differ in each country. If you are interested in applying for the JLPT test, you can find your nearest test center online. The test date for winter is in December and the application period is usually September-October. In December all five levels can be taken but in July only the most difficult levels, levels 1 and 2, can be taken.
There are five levels: N5 (easiest) to N1 (hardest). The Japanese Language Proficiency Test (JLPT) (日本語能力試験 nihongo nōryoku shiken) was created in 1984 in response to the increasing demand of students of the Japanese language to certify their proficiency.
