The Kenya National Examinations Council (KNEC) works out the KCSE mean grade from a candidate’s seven best-performed subjects: Mathematics, the best-performed language and five other subjects. Each subject earns between 1 and 12 points, so the maximum aggregate is 84 points.
Candidates who sit eight or nine subjects can have their strongest results counted. The 2026 KCSE has 1,048,355 candidates and runs until 20 November 2026.
The seven subjects that count
- Mathematics. It always counts.
- The better language. KNEC takes the better-performed language of English, Kiswahili and Kenya Sign Language.
- The five best of the rest. KNEC picks the five highest-scoring subjects from everything else the candidate sat. The weaker of the two main languages can still be picked here.
A candidate must sit at least seven subjects to qualify for the KCSE certificate.
Points for each grade
| Grade | Points | Grade | Points |
|---|---|---|---|
| A | 12 | C | 6 |
| A- | 11 | C- | 5 |
| B+ | 10 | D+ | 4 |
| B | 9 | D | 3 |
| B- | 8 | D- | 2 |
| C+ | 7 | E | 1 |
From aggregate points to mean grade
KNEC adds the points from the seven counted subjects to give the aggregate, then reads off the mean grade:
| Aggregate points | Mean grade |
|---|---|
| 81 to 84 | A |
| 74 to 80 | A- |
| 67 to 73 | B+ |
| 60 to 66 | B |
| 53 to 59 | B- |
| 46 to 52 | C+ |
| 39 to 45 | C |
| 32 to 38 | C- |
| 25 to 31 | D+ |
| 18 to 24 | D |
| 11 to 17 | D- |
| 7 to 10 | E |
A worked example with nine subjects
This is an illustration, not a real candidate. Suppose a candidate sits nine subjects and scores:
| Subject | Points |
|---|---|
| Mathematics | 8 |
| English | 7 |
| Kiswahili | 9 |
| Biology | 6 |
| Chemistry | 5 |
| Physics | 4 |
| Geography | 10 |
| History | 11 |
| CRE | 9 |
- Mathematics counts: 8 points.
- The better language is Kiswahili: 9 points.
- The best five of the rest are History 11, Geography 10, CRE 9, English 7 and Biology 6, which total 43 points.
- Chemistry (5) and Physics (4) are left out of the calculation.
Aggregate: 8 + 9 + 43 = 60 points, which is a mean grade of B.
Do eight or nine subjects help?
They can. Extra subjects give a candidate more chances to replace a weak result with a stronger one. They do not guarantee a better grade, because an extra subject helps only if its points rank among the five best.
The result can also differ from what you might expect from individual subjects. The mean grade reflects only the seven counted subjects, while every subject sat still appears on the results slip and certificate.

Beware of grade-changing claims
KNEC has warned the public against fraudsters who claim they can change KCSE marks or grades for a fee. Rely on KNEC’s official channels for results and grading information.
