The Japanese Language (NAT-TEST, JLPT, and TOP-J) is an examination that measures the Japanese language ability of students who are not native Japanese speakers. The tests are separated by difficulty (five levels) and general ability is measured in three categories: Grammar/Vocabulary, Listening and Reading Comprehension. The format of the exam and the types of questions are equivalent to those that appear on the Japanese Language Ability Test (JLPT).
