The Japan Foundation has been conducting the Japanese Language Proficiency Test (JLPT) overseas in every December.
The content of JLPT will be changed from 4 levels (Level 1 to Level 4) to the new test with 5 levels (N1 to N5) from 2010.
The Japan Foundation will organize the JLPT two times a year in some countries and regions this year, and the first test will be held on Sunday, July 4th with 3 levels of N1, N2 and N3 only.
For Vietnam, we are in the process of preparation for the new test (N1, N2 and N3) in Hanoi on the 4th of this July, while there will be no test in Da Nang and Ho Chi Minh city this summer.
In this December there will be held the new JLPT with 5 levels (N1 to N5) in Hanoi, Da Nang and Ho Chi Minh City.
Further information will be announced soon.
