Apart from National schools, Extra County schools are also very good schools in terms of facilities and performance in the Kenya Certificate of Secondary Education, KCSE, examinations. Most of the schools produce excellent results in KCSE exams and compete favourably with the National schools.
Whereas most parents/ guardians prefer single sex schools (Boys or Girls’ schools), there are a few mixed schools that post good results in KCSE exams.
These schools are found all over the country. They admit the best students from the County where they are established and also countrywide. Form one selection to these schools is done by the Ministry of Education.
