The JLPT places importance not only on knowledge of Japanese-language vocabulary and grammar but also on the ability to use the knowledge in actual communication. In order to perform various "everyday tasks" that require language, not only language knowledge but also the ability to actually use it are necessary. Therefore, the JLPT measures comprehensive Japanese-language communicative competence through Language Knowledge and "Reading" & "Listening". The JLPT is offered in five levels (N1, N2, N3, N4, N5). In order to measure Japanese-language proficiency as thoroughly as possible, test items are designed for each level. N4 and N5 measure understanding of basic Japanese that is mainly learned in the classroom. N1 and N2 measure understanding of Japanese used in a broad range of actual everyday scenes. N3 bridges the gap between N4/N5 and N1/N2.
