BrightKey's Assessment
Oberoi International School (OIS) is a co-educational, day-only international school in Mumbai, founded in 2008 and promoted by the Oberoi group. It operates as 'one school, two campuses': the original Oberoi Garden City (OGC) campus in Goregaon East, and the JVLR campus on the Jogeshwari Vikhroli Link Road, which opened in 2017. The school self-describes as 'India's leading IB continuum school' and is part of the 'IB Preferred Partner' cohort.
OIS delivers the full International Baccalaureate continuum: the Primary Years Programme (Nursery to Grade 5), the Middle Years Programme (Grades 6 to 10), and the Diploma Programme (Grades 11 and 12). The OGC campus has been an IB World School since 2009 and the JVLR campus since 2020, with all three programmes authorized at OGC per the IBO directory. Earlier in its history the school used Cambridge for middle grades, but it now runs as a full IB continuum.
Academic outcomes are a standout. The Class of 2025 posted an IB Diploma average of 35.5 points, well above the global average of 30.58, and the cohort is school-reported to have secured significant university scholarship offers. The school enrolls roughly 2,906 students representing 29 nationalities, with an average class size of 18 and a student-to-faculty ratio of 9:1.
Accreditation runs through the Council of International Schools (CIS) and the New England Association of Schools and Colleges (NEASC), alongside IB authorization. India has no government graded-inspection band for international schools comparable to UK Ofsted or UAE KHDA, so external quality assurance is carried by the CIS/NEASC accreditation cycle and IB programme evaluation rather than a state inspection grade.
Why These Ratings?
Inspection & AccreditationA — Excellent
India operates no graded government inspection regime for international schools, so no verbatim graded band exists and 'S' cannot apply. The school holds full CIS and NEASC accreditation plus IB authorization across PYP, MYP and DP (OGC an IB World School since 2009), which is robust third-party quality assurance and supports an 'A'.
Strengths & Trade-offs
Strengths
- Full IB continuum (PYP, MYP, DP) authorized across the school, with OGC an IB World School since 2009
- Strong DP outcomes: Class of 2025 average of 35.5 points versus a 30.58 global average
- Dual accreditation by CIS and NEASC alongside IB authorization
- Favourable staffing ratios: average class size of 18 and a 9:1 student-to-faculty ratio
- Internationally diverse community of roughly 2,906 students across 29 nationalities
Trade-offs
- No official published fee schedule, so families cannot verify costs from the school directly
- No explicit official statement of the language of instruction (English is inferred from delivery and EAL provision)
- Day-only with no boarding option, limiting access for non-Mumbai or overseas families
- Curriculum history includes a Cambridge phase for middle grades, which can cause confusion about current provision
Is It Right For You?
Best For
- ✓Families seeking a full IB-continuum pathway from early years through the Diploma
- ✓Academically ambitious students targeting strong DP scores and international universities
- ✓Internationally mobile or expatriate families wanting a CIS/NEASC-accredited Mumbai school
- ✓Mumbai-resident families able to commit to a day-school commute
Not Ideal For
- ✕Families needing boarding or residential provision
- ✕Families wanting a British (A-Level) or American (AP) curriculum rather than IB
- ✕Families requiring a published, transparent fee schedule before applying
- ✕Students based outside the Mumbai commuting catchment
Curriculum
Full IB continuum: PYP (Nursery to Grade 5), MYP (Grades 6 to 10) and DP (Grades 11 and 12). OGC has been an IB World School since 2009 and JVLR since 2020. The school previously used Cambridge for middle grades but now runs the full IB continuum.
Fees
The school does not publish an official fee table. Third-party estimates for 2025-2026 indicate roughly INR 5-12 lakh per year, rising toward the upper end for the IB Diploma Programme; an older 2014 profile cited INR 179,000-830,000 and should not be treated as current. Verify directly with the school.
Admissions
Nursery entry requires the child to be 3 years of age as of December 31. The school operates two Mumbai campuses (OGC in Goregaon East and JVLR in Jogeshwari East). Applicants should confirm year-group availability and entry requirements directly with the admissions office.
Campus Life
OIS runs as 'one school, two campuses', the original OGC campus in Goregaon East and the JVLR campus opened in 2017. The community spans 29 nationalities and is supported by services including Social Emotional Learning, EAL and college counselling, with an average class size of 18 and a 9:1 student-to-faculty ratio.
University Placement
