The best international schools in Nairobi

The Nairobi international school landscape

Nairobi has the deepest international school market in East Africa, with around 35 schools serving an international curriculum and a working shortlist of 10 to 12 schools for relocating expat families. The market splits along curriculum lines: a substantial British curriculum cluster led by Brookhouse and the Braeburn group, the dual American and IB International School of Kenya, a strong IB Diploma cluster at Aga Khan Academy and a handful of younger schools, the increasingly credible Cambridge International providers, and a small but excellent boarding option at Peponi outside the city. Fees range from KES 600,000 (USD 4,600) per year at the value tier to KES 3.3 million (USD 25,500) per year at the premium tier.

The reason families relocate to Nairobi from elsewhere in the region, or arrive into Kenya on a multinational assignment, is almost always a combination of work and the quality of life the city offers. Nairobi sits at 1,700 metres altitude, has a temperate climate year-round, and has both established expat neighbourhoods and a strong network of clubs and outdoor activities. The international school market reflects three decades of expat presence and is more mature than the schools markets in Addis Ababa, Kampala or Dar es Salaam. The Nairobi city guide covers the wider expat picture, including healthcare, housing and visas.

How we ranked the 2026 list

Our 2026 Nairobi ranking weights five factors with broadly equal influence: international accreditation and curriculum recognition (Cambridge, IB, AdvancED, Council of International Schools), academic outcomes across IGCSE, A-Level, IB Diploma or American high school credentials, university destinations across the last three years, faculty stability and qualifications, and physical infrastructure including science laboratories, libraries, sports facilities and creative arts provision. We do not weight fees in the ranking itself. Schools sitting outside our top 10 may still be the right fit for specific children, particularly where curriculum tradition or sibling enrolment matters.

We draw on the Kenya National Examinations Council and the Cambridge International schools list, IB Organisation authorisation records, school-published results across the last three years, and our own parent review database. Where claims diverge between school marketing materials and independent records, we use the independent records. Where current data is unavailable, we say so. The ranking below reflects our 2026 view; expect movement between years as new entrants mature and established schools cycle through leadership changes.

The 2026 top 10 schools in Nairobi

Brookhouse School

Brookhouse has been the flagship British curriculum school in Nairobi since the early 2000s. Two campuses operate: the original Karen campus, on a substantial site in the leafy Karen suburb, and the newer Runda campus that opened in 2018 to serve the rapidly growing northern expat community. Each campus runs the full British curriculum from Year 1 to Year 13, with IGCSE in Years 10 and 11 and A-Level in Years 12 and 13. The Karen campus has the deeper sixth form (around 90 students per year group), while Runda is still building scale at the senior end.

Brookhouse's A-Level results have been consistently strong, with around two thirds of recent cohorts achieving A and A grades at A-Level and university destinations including the University of Edinburgh, King's College London, Imperial College, several US Ivies, and East African medical schools. The school invests heavily in co-curricular activities and operates a partnership programme with several UK senior schools that has helped feed pupils into UK boarding at Year 9 and Year 12 transitions. Faculty are largely UK-trained, with a smaller cohort of Kenyan teachers in the lower years. The school has been the default first choice for British curriculum expat families for two decades and the reputation is broadly deserved.

International School of Kenya (ISK)

The International School of Kenya is one of the oldest and most established international schools in East Africa, founded in 1976 under the joint sponsorship of the US and Canadian embassies in Nairobi. The school sits on a 45-acre campus in Kitisuru, on the northern edge of the city, and serves around 1,000 students from over 60 nationalities. ISK is WASC-accredited and runs an American high school diploma alongside the IB Diploma in Grades 11 and 12, with most students taking either the full IB or an AP-heavy American diploma.

Diploma averages at ISK have sat consistently above the global benchmark, with strong representation in Higher Level English, mathematics, biology and history. University destinations include the major US universities (with strong representation at Stanford, MIT, the Ivy League and the top liberal arts colleges), several Canadian universities, Russell Group universities in the UK and increasingly Australian universities. The school's college counselling team is among the most experienced in the region. Faculty are largely North American on three-year contracts, which creates more turnover than at the British curriculum schools but ensures continuity with American university admissions calendars.

Braeburn Garden Estate and the Braeburn group

The Braeburn group operates 11 schools across Kenya and represents the largest single network of British curriculum schools in the country. In Nairobi the campuses are Braeburn Garden Estate (the flagship), Braeburn Imani International, Braeburn Gitanga Road, Braeside School and Braeburn Mombasa Road, plus campuses outside Nairobi at Mombasa, Kisumu, Thika and Nanyuki. Garden Estate is the strongest of the Nairobi campuses for senior years, with the largest sixth form, the deepest A-Level subject offer and the most established university destinations record.

Across the Braeburn network, A-Level outcomes have been credible, with Garden Estate cohorts averaging around 60 per cent A and A grades in recent years. The price point sits below the premium of Brookhouse or ISK without a meaningful compromise on academic depth, which has made the network a useful choice for families with multiple children or those receiving modest education allowances. Family mobility within the group is a genuine advantage if children move between Nairobi, Mombasa or the upcountry campuses for parental work reasons.

Peponi School

Peponi is the only credible British-curriculum boarding option in Kenya for senior years, sitting on a country campus at Ruiru, 35 kilometres north of Nairobi. The school takes both day pupils (mostly from the Runda, Ruiru, Tatu City and northern Nairobi corridors) and boarders. Pupils typically board from Year 9 onwards, with day places dominating the younger years. The campus feels closer to a UK independent school than to a Nairobi day school, with substantial sports facilities, a credible chapel programme and strong house structure.

A-Level outcomes at Peponi have been excellent, with consistent Oxbridge offers in recent years and strong destinations into Russell Group universities and the major US institutions. Faculty are largely UK-trained, with experience in UK boarding and Kenyan schools. The school is selective; expect formal entrance assessment at Year 9 (Common Entrance or equivalent) and sixth form admissions tied to GCSE predictions. For families with two children and an interest in boarding for the older child while the younger continues at a Nairobi day school, Peponi works well.

Aga Khan Academy Nairobi

The Aga Khan Academy Nairobi is part of the worldwide Aga Khan Academies network and runs the full IB continuum from PYP through MYP to Diploma. The campus sits in Parklands and serves around 700 students. Faculty are a mix of locally and internationally hired teachers, with strong continuity at senior leadership level. Diploma averages have sat comfortably above the global benchmark in recent years, with strong representation in Higher Level sciences, mathematics, English and the social sciences.

The Aga Khan Academies network operates a deliberately broad scholarship programme, particularly at senior years, which means the cohort is more socio-economically diverse than at most premium international schools in East Africa. For relocating expat families this contributes positively to the school culture. University destinations span the major UK, Canadian and US universities with growing representation at Asian universities (Hong Kong, Singapore, increasingly Japan). The fee position is notably lower than Brookhouse or ISK for broadly equivalent IB outcomes, which is a significant advantage. Read our Nairobi IB schools guide for the full IB comparison.

Hillcrest International School

Hillcrest is one of the oldest British curriculum schools in Nairobi, founded in 1965 and sitting on a substantial site in Karen alongside Brookhouse. The school runs British curriculum from Reception through Year 13, with IGCSE in Year 10 and 11 and A-Level in Year 12 and 13. The cohort feels smaller and more traditional than at Brookhouse, which suits some families well and is less of a fit for others. A-Level outcomes have been solid, with credible university destinations into the UK Russell Group and the regional Kenyan universities.

The school's natural advantage is continuity across primary and secondary on a single site. Families relocating to Karen with younger children often find Hillcrest a useful option, particularly where the alternative is moving children across town to the Runda Brookhouse campus or to the Braeburn network. Faculty are largely UK-trained with a smaller cohort of Kenyan teachers in the lower years; turnover has been moderate.

GEMS Cambridge International School

GEMS Cambridge International School is part of the worldwide GEMS Education network and the largest British curriculum school in Nairobi by enrolment. The campus sits at Lower Kabete and has invested heavily in facilities over the past five years, with credible science laboratories, sports provision and creative arts space. The school runs Cambridge curriculum (the network's preferred curriculum) through Lower Secondary, IGCSE and A-Level, with IGCSE and A-Level outcomes broadly in line with the Nairobi premium tier despite the lower fee position.

The principal reason to consider GEMS Cambridge is fee. Premium British curriculum tuition at Brookhouse or Hillcrest runs around KES 2.1 to 2.6 million in senior years. GEMS Cambridge sits at KES 1.0 to 1.6 million for the equivalent years, a roughly 35 to 40 per cent discount. For families with two or three children and limited employer education support, the gap is material. The trade-off is a less established university destinations record than the longer-running schools, although this is improving as cohorts mature.

Neighbourhoods and the school commute

Nairobi expat housing is dominated by four areas: Karen, Runda, Kitisuru and Gigiri (the diplomatic quarter), with secondary clusters at Lavington, Westlands, Spring Valley and increasingly the Tatu City corridor north of the city. Each area matches a different school cluster. Karen is dominated by Brookhouse Karen, Hillcrest and Banda. Runda and Kitisuru are dominated by Brookhouse Runda, ISK, Aga Khan Academy and Crawford. Gigiri is closest to ISK and Aga Khan Academy. The Tatu City corridor is dominated by Crawford and the Braeburn network campuses to the north.

Nairobi traffic is the constraint. School run times can double between off-peak and peak. Families should test the route at school-run hours during the house-hunting visit; a 6 kilometre commute on the map can take 35 minutes at 7:45am. School buses run between most of the major schools and the established expat neighbourhoods, with fees of KES 80,000 to KES 150,000 per year. For families with two or more children, the bus is often the better option than two parents doing the school run.

Fees, the all-in picture and the Nairobi premium

Headline tuition at Nairobi's premium international schools runs from around KES 2.1 million per year (USD 16,300) to KES 3.3 million per year (USD 25,500) in senior years, with reception year tuition at roughly half that. The all-in picture, including capital fees, transport, books, uniforms, exam fees, school trips and lunches, adds 15 to 25 per cent to headline tuition. A senior-year place at Brookhouse Karen with a typical loading runs around KES 2.7 to 3.4 million all in (USD 21,000 to USD 26,500). The full Nairobi fees picture is in our Nairobi fees guide.

Nairobi sits below the Gulf premium markets on fee but comfortably above other East African capitals. Premium Dubai schools run AED 85,000 to 110,000 (USD 23,100 to USD 30,000) for the equivalent year. Premium Singapore schools run SGD 40,000 to 60,000 (USD 29,500 to USD 44,200). Nairobi therefore offers credible international schooling at a fee position roughly 15 to 30 per cent below the major Gulf and Asian comparators, which is a meaningful advantage on multi-child packages.

Admissions timing for September 2026 and January 2027

Most Nairobi international schools run a September academic year start, with a smaller cohort starting at January for southern hemisphere transfers and some American curriculum schools. Premium schools have waitlists for popular year groups (Reception, Year 7 and Year 12) that can run 12 months or longer. Plan to apply 9 to 12 months ahead of the intended start date. Brookhouse, ISK and Aga Khan Academy in particular have firm capacity ceilings that mean a Year 7 place that is open in November may not be open in February.

The standard application package across the credible field includes school reports for the last two years, an English language reference from the current head of year or class teacher, an entrance assessment (usually CAT4 or a school-specific assessment delivered remotely), an in-person or video interview with the head of section, and the school's family information form. Premium schools also typically require a recent piece of unprompted written work for older children. Application fees range from KES 5,000 to KES 25,000 per child and are non-refundable. The school finder can help narrow your list.

A closer look at second-tier schools worth visiting

Several Nairobi schools sit just outside our top 10 but warrant consideration depending on family circumstances. Sabis International School, on the Runda corridor, runs the SABIS curriculum and produces strong outcomes for families wanting that specific tradition. Roslyn Academy, an evangelical Christian school in the same area, offers an American curriculum at a notably lower fee point than ISK and is a credible choice for families on smaller education allowances or those wanting a faith-based environment. Rusinga School in Lavington offers a Kenyan-British dual curriculum at a fraction of premium tier fees. Each of these schools attracts a specific cohort and serves it well; the broader cheapest schools guide covers them in more detail.

One additional consideration is sixth-form-only entry, which some families use to optimise senior years. Brookhouse, Peponi and Hillcrest all admit credible numbers of students at Year 12, often with strong GCSE results from UK schools or East African Kenyan school systems. For families with a child finishing IGCSE elsewhere, the sixth-form entry route can open up schools that are otherwise full at lower year groups. The window typically opens in January for September entry and closes by April once predicted grades are received, so plan accordingly.
