Renovations

In November 2009, the school underwent renovations and upgrading for a total cost of 11 billion Ugandan Shillings ($5.8 million USD at the time). The new campus contains primary and secondary sections, 4 science laboratories, 3 computer laboratories, an 8-lane swimming pool, 2 ampitheatres, and multiple fully equipped and multimedia enabled classrooms.^[2]

These renovations gave KISU the capacity to accommodate up to 1,500 students and over 100 faculty members.

Curriculum

KISU's Early years department incorporates KG2 (2 years of age), KG3 (3 years of age) and Reception (4 years of age).

Key Stage 1 (KS1) incorporates Year 1 (5 years of age) and Year 2 (6 years of age).

Key Stage 2 (KS2) incorporates Year 3 (7 years of age),Year 4 (8 years of age), Year 5 (9 years of age) and Year 6 (10 years of age)

In the Primary section, there are 2 or 3 classes per year group, depending on student numbers. Each class has both a teacher and at least one Teaching Assistant (T.A.).

Secondary school

Key Stage 3 incorporates Years 7-9 (approx 11-14 years of age) and these students continue to study the National Curriculum for England, modified to reflect the nature of the school.^[4]

In Years 10 and 11 (15 to 16 years of age) students study an IGCSE programme (similar to UK IGCSEs but more international in nature). These examinations are undertaken through the Cambridge University and assessed by external examinations at the end of Year 11.
