What a Christian international school means in Nairobi
A Christian international school in Nairobi runs a mainstream international curriculum, most often the British pathway, a North American programme or the International Baccalaureate, while carrying a Christian ethos through assembly, chapel or Bible teaching, pastoral care and the values that shape daily life. The academic programme is the same as a secular international school and prepares pupils for the same universities. What differs is the faith framing: worship at the start of the day, a chaplaincy or Bible studies strand, and a stated Christian character that parents can weigh alongside curriculum and fees.
Nairobi families meet two broad types. The first is the faith led international school where Christian life is embedded and openly central to the school culture. The second is the Catholic international school that follows an international curriculum within a Roman Catholic tradition. Both sit apart from the many secular internationals in the city and from local faith schools that teach only the Kenyan national curriculum, which are outside the scope of this international schools guide.
How we chose the schools
We only list schools we profile on this site and that meet two tests: a genuine Christian ethos stated by the school, and a recognised international curriculum rather than the national curriculum alone. Each school below links to its full profile so you can read the detail and verify the claims yourself. We do not rank by a scored league table because no verified parent review data supports one, and we take no referral commission from any school listed. Where a school does not publish a figure such as a founding year or a precise fee, we say so plainly rather than estimate.
The Christian international schools
Three schools in our Nairobi coverage meet the definition above. Each is presented with its curriculum, faith character, fee band and campus area, followed by a link to the full profile.
West Nairobi School, Karen
West Nairobi School is a Christian school in Karen teaching a North American curriculum from Kindergarten to Grade 12. Founded in 1996, it holds accreditation from the Middle States Association and the Association of Christian Schools International, the latter a specifically Christian accrediting body, which makes its faith identity explicit rather than incidental. The published fee band runs at roughly USD 10,300 to 15,500 a year, placing it in the mid tier for an American programme in the city. Karen, on the south western edge of Nairobi, suits families settling in that leafy suburb and the surrounding area.

Rusinga School, Lavington
Rusinga School is a Christian coeducational school on Gitanga Road in Lavington, teaching the British curriculum from the early years through to senior school with Cambridge IGCSE and A Level at the top of the school. Its Christian ethos runs alongside Cambridge International programmes rather than replacing the academic mainstream, so pupils sit the same qualifications as their secular British curriculum peers. Fees sit in the value to mid band, roughly KES 309,000 to 1,212,000 a year depending on stage, which makes it one of the more accessible faith led international options in Nairobi. See the full Rusinga School profile and our British curriculum guide.
St Mary's School Nairobi, Lavington
St Mary's School Nairobi is a Roman Catholic IB World School in Lavington offering IGCSE alongside the International Baccalaureate, with a strong expatriate cohort. Its Catholic tradition places it within the Christian family of schools while its IB authorisation gives it a broad, globally recognised sixth form pathway. The school does not publish a single headline fee, so confirm the current schedule by stage directly with the school and cross check the range on our Nairobi fees pages.

Compare schools side by side
Our school comparison tool lets you put these Christian international schools head to head on curriculum, fee band, stage range and campus area. Then book a short call with our advisor through contact if you want help shortlisting for a specific neighbourhood in Nairobi. No school referral commissions and no obligation.
Fees and value
Fees across these three schools span a wide range because they sit on different curricula and price points. Rusinga is the value to mid option on the British pathway, West Nairobi School is a mid tier North American programme quoted in US dollars, and St Mary's does not publish a single figure. Because Nairobi fee schedules change each academic year and often carry separate registration, deposit and capital items, treat every band here as a starting point and confirm the current schedule with the school before you budget.
For the wider picture, our stage by stage fees pages set these schools in context against the rest of the market. See Nairobi international school fees for primary and Nairobi fees for secondary and sixth form, and the fuller Nairobi international school fees guide for how registration, deposits and extras stack up on top of tuition.
Faith and daily life
The three schools express Christian life differently, and the difference matters more than the label. West Nairobi School and Rusinga carry an openly evangelical Protestant ethos, with worship, Bible teaching and a values framework woven through the week. St Mary's sits in the Roman Catholic tradition, with the rhythms, chaplaincy and pastoral culture that implies. Families from other Christian traditions, other faiths, or none often attend these schools comfortably, but the fit depends on how central worship is to the daily timetable and how the school handles pupils who do not share the dominant tradition.
The honest way to judge ethos is to visit during a normal school day rather than at an open evening. Sit in on an assembly, ask how chapel or Bible studies is timetabled, and ask the school directly what proportion of pupils are not from the school's own tradition and how they are included. A settled Christian school welcomes that question; a defensive answer is itself a useful signal.
How to choose between them
Start from the curriculum your family needs, because that narrows the field fastest. If you are heading towards UK or Commonwealth universities, Rusinga's British pathway or St Mary's IGCSE and IB routes fit naturally. If your return path is North America, West Nairobi School's Kindergarten to Grade 12 programme is the closest match. Then weigh the faith character: a family that wants Christian life at the centre of the school day will read West Nairobi School and Rusinga differently from a family that wants a strong international academic programme within a broad Catholic tradition, which points towards St Mary's.
Finally, weigh location and budget together. Karen and Lavington are different parts of the city with different commutes, and the fee gap between the value to mid British option and a dollar quoted American programme is real. Use the profiles and the Nairobi fees pages to model the true annual cost, visit your shortlist, and talk to current parents from your own community where you can.
