Students are evaluated up to five times per year and are given grades on the Japanese scale of 1 to 5, with 5 being the highest grade. Grades are weighted by term, and year-end grades and class rankings are calculated based on grades and credits earned.

Grades are monitored five times per year, and reports are issued for all students accordingly at the end of the five terms. Students struggling academically receive additional counseling to assist them in the organization of their work and to ensure the proper completion of homework. Both students and their parents receive these grade reports.

Students'grades are based on all of their academic work: daily lessons, homework, class participation, tests and quizzes, formal examinations and projects. Teachers announce the formal grading policy for each course at the beginning of the year.

Students are able to move up to the next academic year if they earn a minimum year-end grade of '2' in all mandatory subjects. In essence, students cannot move up if they have a '1' in any mandatory subject of their program. Upon passing all courses and earning 105 credits, students graduate with a Japanese high school diploma.

The exact number of credits earned depends upon the student's choice of academic program and elective subjects. Total available credits are listed below:
