The Lagos IB landscape
The IB Diploma Programme arrived in Lagos through the American International School of Lagos in the early 2000s and has since spread to a credible cluster of six schools. The current 2026 picture shows three schools running the full IB continuum (PYP through DP) and three more delivering Diploma alongside either a Cambridge primary and lower-secondary pathway or a US high school programme. The depth of the market means there is genuine choice across fee tiers and campus styles, although the practical geography of Lagos (Island versus Mainland, traffic, security) constrains the shortlist for most families.
Cohort sizes are moderate. A typical Lagos IB Diploma cohort runs 35 to 90 candidates per year at the senior schools, larger than in Kuwait or Bahrain but smaller than in Johannesburg or Cairo. Diploma averages at the strongest schools sit credibly in the 32 to 36 point range, with university destinations skewed towards the United Kingdom, the United States, Canada and a growing share to West and North African universities. The expatriate community is a mix of oil and gas, banking, telecommunications, consulting and diplomatic families, with senior management more often choosing the premium tier and middle-management or local-hire packages reaching into the upper-mid tier.
The 2026 IB schools, ranked
American International School of Lagos (AISL)
The senior international school in Lagos. Established 1964. IB Diploma alongside US high school diploma and a substantial AP cohort. Three-year average above 35 points. Strong faculty stability and a long-tenured leadership team. Strong destinations to US universities and credible numbers to the UK, Canada and select European universities. The default first choice for IB-committed expatriate families with US curriculum heritage or planning for North American universities.
British International School Lagos (BIS Lagos)
The leading British curriculum school in Lagos, with a credible IB Diploma cohort running alongside A-Level. Three-year IB average around 34 points. Strong UK university destinations and a growing share to Canadian and Australian universities. Suits British curriculum families wanting IB optionality at sixth form, or families on US heritage who prefer British primary and lower-secondary continuity before transitioning to IB Diploma. The Lekki Phase 1 campus is purpose built and well facilitated.
Greensprings School (Lagos Campus)
One of the longer-established Nigerian-international schools, with full IB Continuum and a credible Diploma cohort. Three-year average around 33 points. Strong destinations to UK, US and Canadian universities. Mixed Nigerian-international cohort, which gives stronger cultural depth than the more expatriate-heavy schools. Particularly attractive for Nigerian-international families and for expatriate families on longer postings who want genuine local integration.
Lekki British International High School (Day Waterman / DWC-Lagos)
British curriculum school with a credible IB Diploma cohort at sixth form. Cohort averages around 32 points. Strong destinations to UK universities. Suits families wanting British curriculum delivery with IB optionality at sixth form. The campus is well established and the parent community is mixed Nigerian-international.
Children's International School (CIS Lagos)
Full IB Continuum school. Three-year DP average around 32 points. Strong cohort outcomes and a credible university destinations record. The Lekki Phase 1 location works for most Island-based expatriate families and the cohort is mixed Nigerian-international. Fees sit at the upper-mid tier rather than the premium level of AISL or BIS Lagos.
Meadow Hall School
Nigerian-owned with full IB Continuum and strong primary years provision. Cohort averages around 31 points. Diploma cohort is smaller and subject choice is more constrained than at the larger schools. Suits Nigerian-international families and those wanting a less expatriate-heavy parent community at fees materially below the premium tier.

Fees and what they cover
Sixth-form tuition for the IB Diploma in Lagos sits between USD 18,000 and USD 26,000 at the premium tier (AISL, BIS Lagos), between USD 9,000 and USD 14,000 at the upper-mid tier (Greensprings, DWC-Lagos, CIS) and around USD 5,000 to USD 8,000 at the mid tier (Meadow Hall). Most published fees are denominated in Nigerian Naira, but inflation and exchange rate volatility mean that USD-equivalent figures are the more reliable planning anchor for expatriate families.
| School | DP tuition 2026 (USD) | All-in estimate (USD) |
|---|---|---|
| American International School Lagos | 24,000 to 26,000 | 28,000 to 31,000 |
| British International School Lagos | 22,000 to 25,000 | 26,000 to 29,000 |
| Greensprings School | 11,000 to 14,000 | 13,500 to 16,500 |
| Day Waterman / DWC Lagos | 10,000 to 13,000 | 12,000 to 15,500 |
| Children's International School | 9,000 to 12,000 | 11,000 to 14,000 |
| Meadow Hall School | 5,000 to 8,000 | 6,500 to 9,500 |
For most expatriate families on senior postings the school fee is reimbursed in part or full by employer packages. Where reimbursement is capped, the upper-mid tier delivers a credible IB Diploma at fees that often sit within the cap, while the premium tier may require a top-up of USD 4,000 to USD 8,000 per child per year. The cost calculator handles the modelling. The detailed picture is in our international school fees in Lagos guide.
University destinations from Lagos IB
The university destination mix from Lagos IB schools is heavily Anglophone, with the United Kingdom, the United States and Canada taking the bulk of cohort leavers each year. AISL leavers head largely to US universities, with strong Ivy League and top-50 destinations from each year's top-quartile candidates. BIS Lagos and DWC-Lagos leavers head largely to UK universities, with Russell Group destinations dominant. Greensprings, CIS and Meadow Hall split more evenly between UK, US and Canadian destinations, with a growing share to South African and Ghanaian universities.
Across the cluster, around 40 to 50 percent of IB leavers head to UK universities, 25 to 35 percent to US universities, 10 to 15 percent to Canadian universities, and the balance to a mix of European, Australian and African institutions. Returning to Nigerian universities after IB Diploma is uncommon for expatriate cohorts but more common for Nigerian-international families at the upper-mid and mid tier schools. For the broader curriculum comparison see IB versus British curriculum and IB versus American curriculum.
Admissions, assessment and waitlists
The Lagos IB Diploma admissions cycle runs September through April for the following September start. AISL and BIS Lagos hold waitlists at Reception, Year 7 and IB1 entry that can run 9 to 18 months at popular cohorts. Upper-mid and mid tier schools have shorter waitlists and more rolling availability. For IB1 entry specifically, applying by January or February is the practical norm, with assessment in February or March and conditional offers in March or April. Late applications are processed at most schools through to July at the upper-mid tier.
Assessment processes are standard: written application, the most recent two years of school records, an internal assessment (commonly a maths and English paper plus year-appropriate reasoning test), a parent interview and a child taster day. AISL and BIS Lagos typically require external referees from the previous school. The IB Diploma is conditional on satisfactory completion of Year 11 at the previous school for late applicants. Our admissions timing by city guide covers the broader calendar.
Island, Mainland and the school commute
Lagos's expatriate family geography centres on the Island: Ikoyi, Victoria Island and Lekki Phase 1. AISL is on Victoria Island, BIS Lagos is on Lekki Phase 1, CIS and Meadow Hall are also on Lekki Phase 1, and DWC-Lagos sits between Ikoyi and Lekki. Greensprings is the outlier, with its primary campus on the Mainland at Anthony Village. For most expatriate families the school choice and the housing choice are made together, with Lekki Phase 1 and Ikoyi the dominant residential areas.
Lagos traffic is severe and is the single most important practical variable in family logistics. The school day starts early, with most schools opening at 7.30am and many families on the road by 6.30am. School bus services are well organised at the premium tier and reach across the Island, though routes from Mainland addresses can mean 5.30am pick-ups. For families based on the Mainland (Ikeja, GRA, Magodo) the practical school choices are Greensprings or one of the smaller Mainland schools rather than the Island IB cluster. For the broader Lagos picture see the Lagos city guide and the moving to Lagos with children guide.
Cohort sizes and subject choice
Cohort size and subject choice matter in Lagos in the same way they do in any IB market. AISL and BIS Lagos run the largest cohorts at roughly 75 to 95 candidates per year, which sustains a credible range of higher level subjects including Economics, Business Management, Psychology, Visual Arts and a credible set of Group 2 languages including French, Spanish and Mandarin. Greensprings and DWC-Lagos run cohorts of 45 to 70, which typically supports the core Group 1 to Group 5 subjects at higher level plus one or two Group 6 options. CIS and Meadow Hall run smaller cohorts of 30 to 50, which constrains higher level options to the most populated subjects.
For families with academically specialist children, the cohort question matters more than the headline cohort average. A child planning to read medicine at a UK or US university will want strong Mathematics Analysis and Approaches at higher level plus Chemistry and Biology, which is reliably available across all six schools. A child planning a less common combination such as History plus English Literature plus a foreign language plus Visual Arts will find that reliably available at AISL and BIS Lagos but may need to compromise at the smaller schools. Worth asking each shortlisted school directly for the specific subject combinations offered in 2026 to 2027, rather than relying on the prospectus alone.
Beyond the IB: alternatives worth knowing
If the IB Diploma is not the only academic option being considered, Lagos has a strong A-Level cohort worth knowing. BIS Lagos and DWC-Lagos both deliver A-Level alongside IB Diploma. Lekki British School and several smaller schools deliver A-Level as the dominant sixth-form pathway. For the full city-wide picture across all curricula see best international schools in Lagos. The Nigerian university entrance pathway (Joint Admissions and Matriculation Board examination) is less commonly used by expatriate families but is the dominant route at the larger Nigerian-owned schools.
One practical note on currency. Most Lagos schools publish fees in Nigerian Naira but accept payment in Naira or USD, with USD payment increasingly preferred at the premium tier given recent Naira volatility. Expatriate families on USD-denominated employment packages typically negotiate USD school fee payment with the employer, which removes the currency risk that has materially shifted fees in Naira terms over the past three years. The exchange rate stabilisation through 2025 has moderated the volatility, but the structural risk remains. Run currency-sensitivity scenarios through the cost calculator if planning a multi-year posting.
A final note on safety and school operations. Most Island international schools operate to strong security standards, with controlled access, perimeter security and well organised pickup and drop-off processes. The schools have generally proved resilient to wider city disruption and most have continuity arrangements for unscheduled closures. For first-time Lagos families, the school is often the most reliable single institution in the early months and an important community anchor.
