In the May/June 2025 IGCSE examinations, California International School registered five candidates. After two months of anticipation, we are proud to announce that our students have once again delivered exceptional results, upholding our strong tradition of academic excellence.
These achievements are not just numbers on paper; they are the reflection of dedication, teamwork, and the unwavering commitment of our teachers, management, parents, and students. Today, California International School confidently stands out as a beacon of genuine and outstanding performance in Eastleigh, Nairobi, and across Kenya.
A Tradition of Academic Excellence
At California International School (CIS), excellence is not an accident—it is a culture. Our consistent IGCSE performance continues to place us among the leading schools in Nairobi and Kenya at large. These results serve as a standard by which parents, fellow schools, and the wider community measure us.
Every year, we strive to prove that quality education, discipline, and hard work lead to outstanding outcomes. The May/June 2025 results reinforce our commitment to providing a world-class education that empowers students to succeed both locally and internationally.
Celebrating the Team Behind the Success
Academic success is always a collective effort, and at CIS, we are blessed with a dedicated and passionate team:
- Mr. Muhajir and Mr. Zeycili – for their exceptional leadership and management.
- Mr. Hassan, Assistant Academic Manager – for his invaluable academic guidance.
- Mr. Abdulbasid – for his consistent support and motivation.
- Mr. Edmont, Class Teacher – for ensuring order, focus, and discipline among the students.
To our teachers, staff, and management: your sacrifice, hard work, and commitment have not gone unnoticed. This victory is as much yours as it is our students’.
Preparing the Next Generation of Champions
While we celebrate the success of our five candidates, our journey continues. Year 11 and Year 6 classes are now preparing for their upcoming examinations. At CIS, we strongly believe that students may not all begin as the strongest—but with dedication, the right guidance, and teamwork, they will always finish strong.
Our mission remains clear: to shape disciplined, knowledgeable, and well-rounded individuals who will thrive in today’s competitive world.
