Grading method

Grades will be evaluated according to the subject matter as follows.
A grade of "Fail (D)" or "Fail (F)"will not be granted.

The GPA [Grade Point Average] system

 In order to promote the internationalization of future education and increase the transparency of the grading system, we have introduced a GPA system beginning with the students who entered in the 2018 school year. The GPA system will indicate a student's relative standing both within and beyond the University. By calculating a GPA, it can become an index for current learning and achievement; we expect this to help students grasp their academic achievement more objectively and utilize it to create their learning plans.

System Overview

 The GPA system is a common method used in European and American universities to evaluate academic grades. Students receive grade evaluations after course completion and it is converted into Grade Points (GP) with the student's overall average computed as a single value.

Calculation Method

 There are five levels of Grade Points (S, A, B, C, D) as shown below.

GP Definition and Letter Grade Evaluation Criteria Criteria out of 100 points
4 Excellent (S) Achieved learning outcomes with exceptionally high grade. 90 points or more
3 Very good (A) Achieved learning outcomes with high grade. 80 points or more
2 Good (B) Achieved learning outcomes with good grade. 70 points or more
1 Fair (C) Achieved learning outcomes. 60 points or more
0 Fail (D) Did not achieve learning outcomes. less than 60 points

Targeted Students

 The students who begin the Master's Course in the 2018 school year and all subsequent years.
 *The GPA system is not used for the doctoral courses.

Targeted Subjects

 All subjects that count towards completion of the Master's Course in the subject categories shown below. However, if a subject cannot be evaluated by the five-level grading scheme due to the nature of the subject, it will be excluded from the GPA calculation.
 ◇ General Subjects
 ◇ Basic Subjects
 ◇ Specialized Subjects

Types of GPAs and Calculation Method
     There is a GPA for the academic year (annual GPA) and a GPA for the entire program (cumulative GPA).
     Here are the calculation methods for annual and cumulative GPAs. (Round off to two decimal digits in calculating a GPA.)
  • Calculation of an Annual GPA
    Annual GPA = The sum for all subjects of (the number of credits for a registered subject for the year × GP of the subject)/The total number of credits for the year's subjects.
  • Calculation of Cumulative GPA
    Cumulative GPA = The sum for all subjects of (the number of credits for a registered subject for the program × GP of the subject)/The total number of credits for the program.
  • How to Treat Retake Subjects

     If a student retakes a subject which he/she has failed, and receives a passing grade or another failed grade as a result, the earlier result and credits are excluded from GPA. (The data before the retake will be excluded.)

    Treatment on Academic Record

     Both the annual GPA and the cumulative GPA will appear on the academic record.

    Notification of completed grade evaluation

     Grades will be reported within three weeks after the completion of the course by the lecturer in charge and will be posted on the homepage and bulletin board, etc.
     Students can confirm the subject registration status and academic performance by means of academic records which can be obtained from the automatic certificate issuing machine in the entrance lobby of the NAIST Library.

    Information concerning objections to academic performance evaluation

     If you have objections to the grading results you received, please submit a "Letter of Objection concerning Evaluation of Academic Performance" to the Academic Affairs Section of the Educational Affairs Division within one month of receiving your grading results.
     (*) Academic Performance Evaluation Objections are possible only when students' cases are deemed as pertaining to one of the following areas.
     (1) Cases where it is thought there are obvious mistakes in grading, such as paperwork errors, etc.
     (2) Cases where there are obvious doubts concerning academic performance evaluation in relationship to the grading standards found in the syllabus, etc.
     A response to an objection is given either orally or in writing through the Academic Affairs Section of the Educational Affairs Division after review by the Graduate School's Education Committee.
