A.1 Yes, it can. Based on the assumption that the student has already acquired some degree of competence with vocabulary and grammar, the Practical Japanese Communication (PJC) Exam contains questions that test the communication skills and business etiquette required at Japanese companies both domestic and overseas, as well as in everyday life in Japan. Combining this with existing Japanese language tests allows us to measure the student's Japanese capabilities more comprehensively.

A.2 The Practical Japanese Communication Exam includes questions about communicative behavior in response to specific situations in different circumstances. It also measures the student's level of understanding of basic business etiquette and the approach to work at Japanese companies.

A.3 A certain amount of correlation has been observed in monitoring test results (*see graph below). Those who hold a higher-level certification from the Japanese Language Proficiency Test tend to achieve higher levels in the Practical Japanese Communication Exam. However, it is not uncommon for even holders of an N1 or N2 level JLPT qualification to achieve only a D level in the PJC, while holders of an N3 level JLPT qualification may achieve a B level in the PJC. We believe this is because the PJC, which emphasizes communication skills, has its own independent metrics. In order to achieve a higher level in the PJC, students must have not only language expertise such as grammar, but also the skills required for practical communication in Japanese.
