Years 12 and 13 comprise the Sixth Form, a pre-university programme that prepares students to enter any university in any country in the world which recognises the British A-Level qualifications.

Year 12 is a general year and introduces students to A-Level’s academic demands. It caters both for students who have come from IGCSE and for those who have entered the programme from other curricula including the KCSE. Students opt for four or five subjects, leading to AS-Level and A-Level qualifications. Year 13 is a specialist year. Students will have selected three subjects from their Year 12 programme for A-Level examinations and now focus on them in depth.

The AS-Level programme was introduced as from the 2000/01 academic year with the intention of widening a student’s course of study and of encouraging students oriented towards the Sciences to follow an Arts course and vice versa. An AS-Level is equal to half an A-Level and the examination can be taken at the end of one year of study, whereas the A-Level examination requires two years of preparation.
