The Kenya National Examinations Council, (KNEC) , grades students based on their achievement in subjects undertaken during the Kenya Certificate of Secondary Education (KCSE) exams in 2021/2022.
This grading is dynamic because it is based on candidates performance in a given year.
Learners who have finished the four-year secondary education cycle are eligible for the Kenya Certificate of Secondary Education (KCSE).

KCSE GRADING.
For you to be graded, you must take a minimum of seven (7) subjects. Out of these, English, Kiswahili and Mathematics are compulsory. You must further take a minimum of two sciences and one Humanity. The seventh subject can as well be chosen from the remaining categories i.e Applied, Humanities, Sciences etc.
In a nutshell, a Candidate must enter for at least 7 subjects which must include:
- From Group I – All the three subjects of Code Numbers 101, 102 and either121 (option “A” )or 122 (option “B”)
- From Group II – At least two subjects of Code Numbers 231, 232 , 233,236( Blind candidates) or 237 for option “B”
- From Group III – At least one subject code of 311,312 or any one among 313/314/315
Note: Only one of the Religious subjects 313, 314 , 315 and one Mathematics option is to be taken. One other subject selected from the remaining subjects in Group II ,III and IV (Code Numbers 441,442,443,444,445,446,447,448,449,450 and 451) or V(Code Numbers 501,502,503,504,511 and 565) - Candidates can sit for 9 subjects and the extra 1 or 2 subjects can be selected from the remaining subjects of groups II, III, IV and V.
Again, it is advisable that you undertake 8 or 9 subjects as opposed to 7. This gives you more grading options. The grade you get is dependent on scores in your subjects. To get your mean score, the Council totals the points that you get per subject.
The highest grade you can get is an A(plain) which carries a point load of 12. Conversely, the lowest grade is an E (that has one point only); See more details on the table below.
| Points | Grade |
| 12 | A (plain) |
| 11 | A- (Minus) |
| 10 | B+ (plus) |
| 9 | B (plain) |
| 8 | B- (minus) |
| 7 | C+ (plus) |
| 6 | C (plain) |
| 5 | C- (minus) |
| 4 | D+ (plus) |
| 3 | D (plain) |
