Best International Schools in Port Harcourt: 2026 Guide for Families

Last reviewed: October 2026 by Emma from ISA. Fee ranges are indicative; always confirm with the school.

Finding the best international schools in Port Harcourt is mostly a question of fit rather than rank. The city is the capital of Rivers State and the centre of Nigeria's oil and gas industry, so many families arrive on a company contract with a short horizon, while others are Nigerians returning home with children used to a British or American classroom.

That mix explains why the schools here combine Nigerian, British and American elements instead of following one pure model. This guide explains how to judge them, which parts of the city they serve, and who each of four schools tends to suit.

Port Harcourt in context: where families live and where schools sit

Most international-minded families live in and around the Government Reservation Area (GRA), where the quieter residential streets and company housing are concentrated. Greenoak International School has its primary campus at 99 Tombia Road Extension and its secondary and sixth form campus at 17 St. Michael's Crescent, both in GRA Phase Three. CrestForth International School is at 10 Ambrose O. Ogbonna Avenue, off Stadium Road in Elekahia, close to GRA. Koothill International School is listed at 6 Koothill Drive, Okuru Odili Road.

Brookstone School splits its sites: the nursery and primary school sits in GRA, while the secondary school and foundation programme are at Igwuruta on the edge of the city. The NCUK, the university foundation consortium that runs a centre there, says Igwuruta is about 15 minutes by car from Port Harcourt International Airport. If your housing is in GRA, ask Brookstone about the secondary school bus before you commit, because the daily distance is the practical trade-off for the larger campus.

Curricula available in Port Harcourt

• Nigerian curriculum and WASSCE: the West African Senior School Certificate Examination is run by the West African Examinations Council, and most schools in the city prepare pupils for it alongside other routes.
• British curriculum and Cambridge IGCSE: Brookstone's secondary school offers British and Nigerian curricula with Cambridge International Examinations and IGCSE, according to published school information.
• Hybrid Nigerian, British and American: Greenoak says it runs a hybrid curriculum covering all three, and describes its primary programme around the International Primary Curriculum.
• NCUK International Foundation Year: Brookstone hosts an NCUK centre, a one-year route into partner universities in the United Kingdom and beyond.

There is no IB school in our Port Harcourt listings, so families who need the IB Diploma for a child entering the final years should plan a move or boarding elsewhere.

Schools to consider in Port Harcourt

Greenoak International School

Greenoak takes pupils aged 5 to 10 on its primary campus and 10 to 17 on the secondary campus, with a sixth form for ages 17 to 18, and describes itself as a day and boarding school. Wikipedia records that the primary school opened in September 2004 and the secondary in 2008, and that roughly 25% of pupils are expatriates and 75% Nigerian.

It suits families who want one name from age 5 to the end of school and some choice between Nigerian and overseas examination routes. Fees are not published on the school website, which says the bursar gives full payment details during admission; it does mention termly payment, annual payment on request and case-by-case reductions for families with three or more children. Check which exams your child will sit in the final two years before you choose a track.

Brookstone School

Brookstone describes itself as an independent, coeducational school with a Christian ethos, covering nursery, primary, secondary and a foundation programme. Wikipedia dates the secondary school to 2006, and says pupils sit Cambridge IGCSE and WASSCE, plus NECO, TOEFL and SAT at different points. The Pie News reported in March 2013 that NCUK would launch its International Foundation Year there, with the first cohort starting in September 2013.

This is the school to look at if university entry in the UK is the goal, since the foundation year is a separate route into British universities. The main caution is the Igwuruta location for older pupils, so ask about transport and whether boarding is offered for your child's age.

Koothill International School

Koothill's own website describes a school from creche through nursery and primary to secondary, with an e-learning portal and online results for parents. It says it is affiliated to Vancouver Island University in Canada and links to a Vancouver Island study page, which may interest families thinking about study in Canada.

It suits families who want an all-through school on the Okuru Odili Road side of the city and a possible Canadian pathway. The website does not list a curriculum, accreditation or fees, so ask for the scheme of work, the exams offered in the final years and the current fee schedule in writing.

CrestForth International School

CrestForth is a private early years and primary school off Stadium Road. The school describes a hybrid of Cambridge Assessment International Education programmes, the International Early Years Curriculum and the International Primary Curriculum for pre-toddler to primary pupils. It tends to suit families with young children who live near GRA and Elekahia and want a local early years and primary school before moving to a secondary campus elsewhere.

Because it stops at primary, plan the next step early. Ask where recent leavers have gone and whether those secondary schools use the same curriculum language, so the transition is smooth.

What makes a school the best fit in this city

Start with the exit route. If your child will finish school in Nigeria, WASSCE and a recognised foundation route are fine. If you expect to move to the UK, Canada or the US, Cambridge IGCSE, a foundation year or SAT preparation matter more. Next, check practical resilience: power supply, water, security arrangements, and how the school handles disruption to the school day. Then look at commute, since traffic in a city this size can double a short journey.

None of these four is a single answer. Greenoak fits the widest range of ages, Brookstone fits university-focused teenagers, Koothill fits families who want an all-through school with a Canadian link, and CrestForth fits a young family at the start of schooling.

International school fees in Port Harcourt

Fees are charged in Nigerian naira (N). Full schedules are rarely published online, so the figures below are planning ranges. Legit.ng, a Nigerian news site, updated its list of school fee estimates in May 2026. It put Greenoak at about ₦1.9 million a year, the Norwegian International School at about ₦1.84 million, Bloombreed High School at about ₦1.5 million and Charles Dale Memorial International School, boarding only, at ₦2.04 million. The same list put the American International School of Lagos at about ₦5.5 million, the highest on it. The site describes all of these as estimates, not quotes, and they are secondary school figures, so younger year groups may differ. Boarding is priced separately.

• Registration and assessment fee: a one-off charge at application.
• Acceptance deposit or development levy: ask whether it is refundable.
• Uniform: Greenoak says uniforms are customised and sold only through its own uniform store.
• Transport and meals: usually billed per term.
• Examination fees: WASSCE, IGCSE and SAT entries are normally extra.
• Devices and trips: not always covered by tuition.

The Compulsory, Free Universal Basic Education Act 2004 says every government in Nigeria shall provide free, compulsory universal basic education for every child of primary and junior secondary school age, and that services in public primary and junior secondary schools are free of charge. Private international school fees are therefore a choice, not a legal requirement, and families sometimes compare them with the public route.

Practical advice before you apply

Ask about currency and increases. Naira fees can be revised between sessions, and some contracts quote in dollars. Ask which currency applies, how often fees are reviewed and whether paying the full year in advance fixes the price.

Visit more than one campus. Two schools here run separate primary and secondary sites, so visit both and time the journey at school-run hours.

Look for scholarship and sibling terms. Greenoak says its board awards academic scholarships to primary and secondary pupils scoring at least 97% in core subjects. Ask each school what it offers.

Frequently asked questions

Which is the best international school in Port Harcourt?

There is no single best school. Greenoak International School suits families wanting one school from age 5 to 18 with Nigerian, British and American elements. Brookstone School suits teenagers aiming for UK universities, thanks to Cambridge IGCSE and an NCUK foundation year. Koothill and CrestForth have little published detail, so ask each for its curriculum and fees in writing.

How much does an international school cost in Port Harcourt?

Few schools publish fees. Legit.ng's May 2026 estimates put Greenoak at about ₦1.9 million a year, the Norwegian International School at about ₦1.84 million and Bloombreed High School at about ₦1.5 million, for secondary pupils. Treat these as estimates, not quotes, and ask each school for its schedule, as boarding, transport and exams cost extra.

Is there an IB school in Port Harcourt?

Not among the schools we list. Port Harcourt schools tend to combine Nigerian WASSCE with British Cambridge IGCSE, and some add American elements. Brookstone hosts an NCUK International Foundation Year as a route into UK universities. Families who need the IB Diploma should plan for a move or boarding in another city.
