Two Philosophies of Academic Assessment
Indian higher education hosts two fundamentally different approaches to grading: absolute grading, which assigns marks to fixed grade categories regardless of class performance, and relative grading, which distributes grades based on how students perform against each other. Both are in active use in India, and the choice between them affects how transcripts are interpreted by employers, graduate schools, and credential evaluators.
The debate between the two systems has intensified since the UGC introduced the Choice Based Credit System (CBCS) in 2015, which recommends absolute grading while permitting relative grading, leaving institutions free to choose.
What is Absolute Grading?
Absolute grading assigns grades based on fixed mark ranges that are determined before the examination takes place. A student earns grade A+ by scoring in the range 85–100, a grade A by scoring 75–84, and so on, regardless of whether the rest of the class scored higher or lower.
UGC-Recommended Absolute Scale
The UGC CBCS framework specifies the following absolute grading scale:
| Grade | Grade Point | Marks Range | |---|---|---| | O (Outstanding) | 10 | 85–100 | | A+ (Excellent) | 9 | 75–84 | | A (Very Good) | 8 | 65–74 | | B+ (Good) | 7 | 55–64 | | B (Above Average) | 6 | 50–54 | | C (Average) | 5 | 45–49 | | P (Pass) | 4 | 40–44 | | F (Fail) | 0 | Below 40 | | Ab (Absent) | 0 |, |
Under this framework, SGPA (Semester Grade Point Average) is calculated as the credit-weighted mean of grade points, and CGPA is the cumulative SGPA across all semesters.
Institutions Using Absolute Grading
- University of Delhi (DU): Adopted UGC CBCS absolute scale for all affiliated colleges post-2015
- Anna University: Uses its own absolute scale (O=91–100 at 10 points, A+=81–90 at 9 points, etc.)
- Calcutta University: Traditional marks-based system (percentage marks, not grade points) functioning as de facto absolute grading
- Most state affiliating universities: Following UGC CBCS, particularly after National Education Policy 2020 implementation pressure
Advantages of Absolute Grading
- Transparency: Students know exactly what marks they need to achieve a particular grade before the exam
- Portability: Two students from different institutions with the same CGPA can be compared, assuming similar marking standards
- Employer clarity: A CGPA of 9.0 consistently means the student scored 85%+ average across their program
- Incentive to collaborate: Students are not competing for a fixed number of A grades, everyone can potentially achieve top marks
Limitations of Absolute Grading
- Examiner calibration problems: If papers are harder one year, marks drop and more students fail, the scale doesn't adjust
- Inter-paper comparison: A student taking a harder elective earns the same grade as someone taking an easier one if both score 80
- Institutional marking standards vary: An 85 at one university may represent different cognitive achievement than an 85 at another
What is Relative Grading?
Relative grading (also called normalisation, curve grading, or relative assessment) distributes grades based on class performance. The grade boundaries are set after seeing the class's marks distribution, not before.
The most common implementation in Indian institutions is the Normal Distribution (bell curve) model: - The mean (μ) and standard deviation (σ) of the class marks are calculated - Grade boundaries are set at intervals around the mean: grades above (μ + 1.5σ) are AA, (μ + 0.5σ) to (μ + 1.5σ) are AB, and so on - This ensures that approximately the same proportion of students receive each grade every year, regardless of absolute marks
IIT Grading System
The Indian Institutes of Technology are the most prominent users of relative grading in India. The IIT grading framework uses a 10-point scale with grades AA (10), AB (9), BB (8), BC (7), CC (6), CD (5), DD (4), and F (0). The actual marks cut-offs for each grade are determined relative to the class performance for that particular course and semester.
At IIT Bombay, the instructor determines a provisional marks distribution, and department-level procedures ensure consistency. At IIT Madras, the grade distribution parameters are published in course syllabi, with instructors having flexibility within institutional norms. The net result is that approximately 25–30% of students receive AA or AB in most courses, with the remainder distributed across lower grades.
IIM Grading System
The Indian Institutes of Management use a similar relative approach. IIM Ahmedabad and IIM Calcutta use a 4-point (or variant) letter-grade scale where the distribution is managed to ensure that the top 20–25% of the class receive an A, the next 25–30% receive a B, and so on. The exact grade boundaries are set by each faculty member but must be reported to and approved by the academic office.
Other Institutions Using Relative Grading
Several NITs (National Institutes of Technology) apply relative grading, particularly in core engineering courses where large cohort sizes make absolute grading outcomes more variable. BITS Pilani is known for its strict relative grading system that produces grade point distributions calibrated to the cohort.
Advantages of Relative Grading
- Adjusts for paper difficulty: A difficult exam doesn't result in mass failures, grades reflect relative performance
- Maintains grade distribution consistency: Employers and graduate schools can rely on a consistent distribution over time
- Reduces grade inflation: Because grades are constrained by a fixed distribution, instructors cannot award everyone an A
Limitations of Relative Grading
- Penalises strong cohorts: A student who scores 85% in a class where the average is 80% may receive a B, while in a different cohort where the average is 60%, the same absolute score earns an AA
- Reduces collaboration: In a relative system, helping classmates can reduce your own grade standing
- Opaque for external evaluators: Employers and foreign universities cannot easily interpret a relative grade without knowing the class average
- CGPA cross-institution comparison is impossible: A CGPA of 8.5 from IIT Madras under relative grading cannot be directly compared to a CGPA of 8.5 from Delhi University under absolute grading
CBCS and the Institutional Choice
UGC's CBCS guidelines (2015, revised 2019) explicitly recommend absolute grading but state that "in case an institution chooses to follow relative grading, it should provide the mean and standard deviation of marks alongside the grades on official transcripts." This guidance is often not followed in practice, transcripts from relative-grading institutions rarely include the statistical context.
The National Education Policy 2020 calls for holistic and multi-dimensional assessment but does not mandate either system, leaving the choice to institutions and the newly formed Higher Education Commission of India (when operationalised).
For Academic Administrators
Whether an institution uses absolute or relative grading, the student management system must:
- Support configurable grade scale definitions, not hard-coded to any single scale
- For relative grading: Calculate class mean and standard deviation at semester end and derive grade cut-offs algorithmically
- For absolute grading: Apply fixed marks-to-grade mapping per course or department
- Document the grading methodology on transcripts to help employers and foreign institutions correctly interpret grades
- Support CGPA recalculation when grade boundaries change after faculty review
OpenEduCat's Gradebook module supports both absolute fixed-range grading and configurable relative grading models, with per-course and per-department grade scale settings, giving institutions the flexibility to implement either system accurately.
