At Treshaw International School, our Senior School offers a structured and globally recognized academic journey through the Pearson Edexcel British International Curriculum, spanning from Key Stage 3 to A Levels. This stage is designed to challenge students, sharpen their intellect, and prepare them for higher education and global opportunities.
In Key Stage 3, students follow the Pearson Edexcel iLower Secondary Curriculum, which builds a strong foundation in core subjects while introducing a broader global perspective.
Students in Year 9 begin transitioning into the IGCSE Curriculum starting in Term 1.
Year 7 to 9: Intakes take place within the first month of every term.
Bridging Program: Students transitioning from the 8.4.4 system (Standard 8 with 300+ KCPE marks) may join our iLower Secondary Bridging Course (January 10 – July 30). Upon passing internal exams, students proceed to Year 9 Edexcel in September.
