Statistical grades are statements of relative quality, which depicts the quality of the student’s work in relation to similar students and to what might reasonably to expect of them, that determines his/her grades. In view of this, the grading system is preferred over the marking system. Of course the grading system removes several anomalies; however in developing countries like India, grading system is still a foreign language to most of the stake holders including teachers who play a very important role. The autonomy enjoyed by each teacher in grading a student apart from integrity also need the ability to change over from marking system to grading system. The method has to evolve itself. Thus, it is expected that several discrepancies may appear at initial stages, which may hamper the career of a student. The grading system which is statistical in nature will apply and found efficient for the normal distribution of marks. Any variations from this, which may appear because of less number of students, the teacher, play a very important role in grading. The methodology adopted not only need to be transparent but also justifiable. However, in case of large number of students, if anomaly appears then it will be basically because of some other reasons like discrepancy in question paper, method of evaluation etc. i.e. if the distribution although Gaussian in nature, it will be shifted from the expected mean or skewed one. In such cases, there is a necessity of looking in to the methodology adopted. In the presentation proposed, apart from being addressing the problems associated, a new methodology is proposed to overcome them. The method was applied to a large number of cases and has been shown working reasonably well.
