The implementation of the Letter Grading Directive 2078 BS (लेटर ग्रेडिङ निर्देशिका, २०७८) by Nepal's Curriculum Development Centre (CDC) and the National Examinations Board (NEB) marks a significant educational shift toward transparent competency assessment.
1. The 35% Theoretical Examination Threshold
Under the revised directive, students must secure a minimum of 35% in the theoretical examination of each subject. For standard 75-mark theory papers, this translates to at least 26.25 marks (rounded to 27). Scoring below 35% in theory results in an NG (Non-Graded) classification, regardless of how well the student performed in the practical section.
2. The 40% Internal & Practical Threshold
For internal assessments, laboratory practicals, and project work (typically 25 marks), students must secure a minimum of 40% (10 marks out of 25). Both theoretical and internal scores are documented separately on the final grade sheet before the cumulative grade point is computed.
3. Understanding the 8-Tier Letter Grading Scale
| Percentage Interval | Letter Grade | Grade Point (GP) | Description |
|---|---|---|---|
| 90% and above | A+ | 4.0 | Outstanding (सर्वोत्कृष्ट) |
| 80% to below 90% | A | 3.6 | Excellent (अत्युत्तम) |
| 70% to below 80% | B+ | 3.2 | Very Good (उत्कृष्ट) |
| 60% to below 70% | B | 2.8 | Good (उत्तम) |
| 50% to below 60% | C+ | 2.4 | Satisfactory (सन्तोषजनक) |
| 40% to below 50% | C | 2.0 | Acceptable (ग्राह्य) |
| 35% to below 40% | D | 1.6 | Basic (आधारभूत) |
| Below 35% | NG | 0.0 | Non-Graded (अवर्गीकृत) |
4. Grade Increment (Supplementary) Opportunities
Students who receive an "NG" in up to two subjects are eligible to sit for the immediate Grade Increment Examination conducted by the NEB. Clearing these subjects enables immediate admission into Grade 11 (+2) Science, Management, Humanities, or Education faculties without losing an academic year.
