About dis school — The Lagoon School
The Lagoon School na one of Lagos few explicitly single-sex girls school and one of only two Island-based British-curriculum girls secondary option (the other one na Vivian Fowler for Mainland). Dem found am 1994 for Lekki Phase 1, Lagoon don build specific reputation on two thing: STEM outcome and structured leadership development. The school na unusual because im senior girls consistently dey outperform Mainland Nigerian-curriculum peer school for WAEC mathematics and physics — pattern wey the founding head dey attribute to single-sex classroom and to deliberate STEM-first curriculum design. Class size dey small (18-20), teaching cohort get low turnover, and SS3 cohort don dey place with growing frequency into UK STEM programme (Imperial, Warwick, Bath). Wetin Lagoon no dey offer na co-education, boarding, or A-Level — the model dey deliberately narrow. For family where single-sex education na preferred choice, Lagoon na the strongest Island-based option.
Strengths & trade-offs
✓ Strengths
✓Girls-only single-sex environment
✓STEM emphasis with strong mathematics + physics WAEC results
Lagoon dey do competitive assessment three times every year. Reception na play-based; Year 1 upward include English and Mathematics paper. Year 7 entry dey competitive (usually 60 applicant for 30 place). Application fee na ₦30,000 (no refund). Sibling priority dey.
School fee na only part of the bill. See wetin family dey actually pay:
School bus₦200,000–₦400,000/yr
Uniform₦60,000–₦120,000
Books + IGCSE entries₦80,000–₦200,000/yr
Lunch₦200,000–₦300,000/yr
ECAs and trips₦40,000–₦120,000/yr
Campus & facility
2.5-acre Lekki Phase 1 campus with 25 classroom, three science lab (dem upgrade am recently for STEM), 200-seat hall, small swimming pool for PE, multi-court for netball and basketball, and 6,000-volume library. The school dey run fully on solar + inverter — no on-site generator.
Lagoon dem found am on the belief say single-sex education dey improve result for girls, especially for STEM and leadership. The school dey cite consistent overrepresentation of dem alumni for Lagos STEM and finance role.
The founding rationale be say girls STEM outcome dey improve for single-sex classroom environment — claim wey international education research dey back. Lagoon continued WAEC mathematics and physics performance (typically 90%+ credit-pass, above Lagos private-school average) dey support the founding thesis empirically.
No — Lagoon dey finish for Year 11 with IGCSE. Most Year 11 leaver dey transfer to LBS Sixth Form, BIS Sixth Form, Bridge House, or UK Sixth Form college.
No — the school dey finish for Year 11 with IGCSE. Sixth Form-bound leaver dey transfer to LBS Sixth Form, BIS Sixth Form, Bridge House, or UK Sixth Form college. Absence of in-house Sixth Form na deliberate — Lagoon founding view be say the transition itself na valuable growth step for girls.
Strong — recent cohort don average 75%+ A*-A grade. STEM subject (Mathematics, Physics, Chemistry) consistently dey perform better than humanities, reflecting the school deliberate STEM emphasis.
Both na girls-only. Lagoon na Island-based, British-curriculum, day-only, secular. Vivian Fowler na Mainland-based (Oregun), Nigerian-curriculum with IGCSE add-on, boarding-heavy, Christian-affiliated. Choice come down to curriculum, boarding, and location.
Christian-founded but non-denominational and inclusive. Daily assembly include Christian devotion. Non-Christian girls dey welcome and dem no dey exclude them from any activity.
STEM na the school deliberate specialisation — extra hour per week on mathematics and science from Year 7 upward, dedicated physics and chemistry lab, coding integrated across curriculum from Year 4. Girls dey prepare for STEM university application from Year 9.
Netball (the strongest), basketball, swimming, athletics, table tennis, and badminton. The Lagoon netball team don win Lagos Inter-School Championship four times for the last 10 years.
Christian-affiliated but non-denominational and non-mandatory. Morning assembly include brief Christian devotion but non-Christian pupil no dey required to participate. School ethos more academic than doctrinal.
