Celebra uses the official Kenya National Examinations Council (KNEC) grading system for all exam results.
The KNEC grading system uses 12 grade points from A (highest) to E (lowest):
| Grade | Percentage Range | Points | Interpretation |
|---|---|---|---|
| A | 80% - 100% | 12 | Excellent |
| A- | 75% - 79% | 11 | Very Good |
| B+ | 70% - 74% | 10 | Good |
| B | 65% - 69% | 9 | Fairly Good |
| B- | 60% - 64% | 8 | Average |
| C+ | 55% - 59% | 7 | Fair |
| C | 50% - 54% | 6 | Satisfactory |
| C- | 45% - 49% | 5 | Acceptable |
| D+ | 40% - 44% | 4 | Below Average |
| D | 35% - 39% | 3 | Weak |
| D- | 30% - 34% | 2 | Very Weak |
| E | Below 30% | 1 | Fail |
Celebra automatically calculates grades using this formula:
(score / total_marks) × 100Example:
Score: 72/100 → Percentage: 72% → Grade: B+ (10 points)
For overall student performance, the mean grade is calculated by:
Example: A student with points 10, 9, 8, 11, 7, 9, 8 in 7 subjects:
Total = 62, Mean = 62/7 = 8.86 → B- (rounds to 9 points)
In Celebra, the pass rate is calculated as:
This aligns with university admission requirements in Kenya where a minimum of C+ is typically required for degree programs.
