The Graduate School of Language Science at Kanda University of International Studies has professors with excellent research results and teaching experience, as well as modernized research facilities. We pursue research activity to establish a base of theoretical and applied linguistics research. Since 1996, when the COE (the central research base of language science) was established, the full-time instructors, researchers who have a doctoral degree, graduate school students, and eminent researchers belonging to the other domestic and foreign universities or research institutes have participated in joint research. The school's purpose is to make international contributions to many fields of modern language study and to foster excellent young researchers.

The graduate school offers two majors in the master's program and one in the doctoral program. In the former program, the majors are separated into English linguistics and Japanese linguistics. In both courses, basic training about logic and description is included in order to establish a base of broad fields of applied research such as theoretical linguistics research, foreign language pedagogy, social linguistics, mechanical language processing, psycholinguistics, and neuro-linguistics including speech impediment and the appropriate treatment. As for foreign language pedagogy, a substantial curriculum is offered on the basis of general theory of language education.

In the graduate school, continuing education is emphasized. In order to create a curriculum to provide a schedule to foster experts, all lessons are given from the afternoon to the evening (the first period begins at 1:50 p.m. and the eighth period ends at 8:00 p.m.). These times enable adult students to take lessons at night and to cope with both jobs and schoolwork.

For adult students who desire to reacquaint themselves in fields closely related to language research and education, the system of admitting adult students on the basis of recommendation was started in 1999. Such adult students are expected to motivate and inspire other students with less experience in society.
