ISK High School
The International School of Kenya's High School serves a diverse community of students in Grades 9–12 (ages 14–18) at a transformative stage of their educational journey. We offer an inclusive, dynamic, and supportive environment designed to meet a wide range of talents, interests, and aspirations—recognizing that every student brings unique strengths, ambitions, and needs to our classrooms.
Our program emphasizes inclusive learning, ensuring that each student grows academically, socially, and emotionally while developing the skills, knowledge, and mindset needed to thrive beyond school. Whether students pursue the ISK High School Diploma, the International Baccalaureate (IB) Diploma Programme, or a combination of pathways, they are supported in building competencies aligned with their post-secondary goals.
We prepare our students for pathways to global success—universities and colleges around the world, transition years, apprenticeships, trade schools, entrepreneurship, and countless other opportunities. Through rigorous academics, personalized learning, service-learning experiences, and interdisciplinary inquiry, students develop the independence, resilience, and global perspective needed to contribute meaningfully to their communities and the wider world. In our High School, students are challenged to pursue their passions, question the status quo, and imagine themselves as agents of positive change. It is here that young people discover not just who they are, but who they want to become.
Principal's Welcome
“Welcome to ISK High School, where our vibrant campus provides an open, supportive environment for students to explore ideas, collaborate, and grow intellectually and personally. We believe the best learning happens when students feel safe to take risks, ask questions, and engage deeply in their learning.
Our program combines rigorous academics with a warm, supportive community and is designed to offer meaningful, relevant learning experiences that connect to students’ interests and aspirations.
Beyond the classroom, students learn through field studies across Kenya, service projects, independent study, and global co-curricular opportunities that broaden perspective and build real-world skills. We look forward to supporting students through these important years of growth and discovery.”
