Many schools in the Mt Kenya region recorded improved performance in the 2025 Kenya Certificate of Secondary Education (KCSE) examination compared to the 2024 edition.
School principals attributed the performance to hard work, discipline, and support from both the teaching and non-teaching staff, as well as the parents.
In Kiambu County, some of the top performers include Alliance High School with a mean score of 10.47, Alliance Girls High School (10.065), Nova Pioneer Tatu Boys High School (10.2), and Loreto High School, Limuru (9.404).
In Nyeri County, many schools recorded an improvement in their mean score despite an increase in the class population as compared to last year.
At Kagumo Boys High School, the class that had 515 candidates recorded a mean score of 9.9.
This was an improvement as compared to the school’s 2024 mean score of 9.5 from a class of 446.
According to the Chief Principal Dr Silas Mwirigi, in the 2025 class, only six students did not qualify for university admission.
“We attribute the success to our parents and teachers who worked tirelessly to ensure that our candidates had a good studying environment. We also did a lot of revision to prepare our candidates for the examination,” Dr Mwirigi said.
He said in 2025, the school recorded 75 A (plain) grades, A- (minuses) were 149, B+ (plus) were 111, and 83 B (plain). Additionally, the school recorded 63 B- (minus), C+ (plus), six C (plain), and two C- (minus).

“This means 537 candidates from the 2025 class will be transitioning to university. This is a great improvement from a mean of 9.36 in the 2024 national exam,” Mr Rutere said.
He said the students had narrowly missed their target of 10.56 due to hard work and dedication.
