The Ministry of Education has authorized a maximum of 30 subjects to be offered in secondary schools in Kenya under the 8.4.4 curriculum. Schools can decide, according to manpower and resources, the list of KCSE subjects (and codes) that will be examined by KNEC.
KNEC requires a student to do at least 7 subjects (a maximum of 9) in order to be graded and awarded with a KCSE certificate.
The 7 subjects must include English, Kiswahili, Mathematics (A or B), at least 2 Sciences, at least 1 Humanity, and any other remaining in the list.

Usually, the school decides the list of subjects to be offered hence a student does not have much choice but to select from the available list.
