From humble beginnings in 2016 to a beacon of educational excellence in Narok County — the journey of Olderkesi Senior School.
"Building Leaders, Changing Lives, Inspiring Generations!"
From 2016 to 2026, Olderkesi Secondary School has transformed from a small community school with 93 students and 5 teachers into a thriving institution with 1,313 students, 50 staff members, and over 1,000 university placements. This is a story of vision, faith, and community.
From humble beginnings to a thriving institution, Olderkesi Senior School's journey reflects resilience, growth, and a commitment to shaping future leaders.
Olderkesi Secondary School was established with just 93 students, 5 teachers, and 4 classrooms. The staff room was a luxury — teachers resorted to taking tea under a tree and in the open. The first administration block served as the principal's office, staffroom, and bursar's office. "Kweli Mungu ametutoa mbali!"
The first pioneer class (2016-2019) began their journey. The first teaching staff included Sena, Mr. Yenko, Mr. Maitai, Mr. Lenkume, Mr. Sairowua, Mr. Mayiani, and Mr. Reyia. The vision bearer, Mzee Sayialel, laid the foundation for a legacy that would outlive him and change generations.
The pioneer class sat their first KCSE examination with 90 candidates, achieving a mean score of 4.52 and 5 direct university entries. The first graduation ceremony was held, and top students received their awards. The Principal was accompanied by the first Governor of Narok, His Excellency Hon. Samuel Tunai, on an official function.
A major leap in performance: 93 candidates achieved a mean score of 7.13 with 85 direct university entries. The school began nurturing talents through Sunday services, sports, and co-curricular activities. Proverbs 22:6 — "Train up a child in the way he should go, and when he is old he will not depart from it."
133 candidates sat KCSE, achieving a mean score of 7.72 with 117 direct university entries. The school was awarded at the County Academic Educational Day for Agriculture, posting a mean of 11.5 out of 12 points. Collections of trophies accumulated in both academics and extra-curriculum. Teachers were treated to a motivational trip to Mombasa (2022) courtesy of Mzee Sayialel.
158 candidates sat KCSE with a mean score of 6.8 and 98 direct university entries. Student leaders began receiving mentorship from national leaders including Hon. Ledama Ole Kina and Hon. Gabriel Tong'oyo. The school strengthened its prefects' mentorship programme and community outreach initiatives.
212 candidates achieved a mean score of 7.87 with 117 direct university entries. The school continued to give back to society through charitable work, supporting needy students with fees and learning materials. Students and staff received blessings from elders after charity work. Galatians 6:9 — "Let us not become weary in doing good, for at the proper time we will reap a harvest if we do not give up."
The school's best KCSE performance yet: 263 candidates achieved a mean score of 8.02 with 256 direct university entries. This was the highest mean score in the school's history. The success story of former students turned teachers — Mr. Parkesui and Mr. Lepore — inspired the current generation. Miss Becky Kipees, a former student, became a Bachelor's degree holder in Education.
319 candidates achieved a mean score of 7.8 with an unprecedented 308 direct university entries — the highest number of students sent to university in a single year. The seventh graduation ceremony was held. The team that achieved this milestone was celebrated by parents with a luncheon at Mara Napa. Total university placements since 2019 reached 1,052 students.
Olderkesi Senior School celebrates its 10th anniversary with 1,313 students, 50 staff, 18 classrooms, 3 laboratories, and 6 dormitories. The school has produced over 1,000 university graduates and continues to transform lives. The Strategic Plan 2026-2036 envisions modern staff houses, digital classrooms, a dairy farm, school bakery, and biometric systems. "This is only the beginning. The next 10 years will be even bolder."
From a mean score of 4.52 in 2019 to 8.02 in 2024 — a testament to dedication, quality teaching, and student resilience.
