How the IB-Schools.com Rankings Work

The IB-Schools.com global, India, and Mumbai rankings are calculated from a single metric: the average IBDP points score across a school's graduating cohort in the May examination session. There are no application fees, editorial judgements, surveys, or sponsored placements. A school's position is determined purely by its results.

• Ranking metric: average IBDP points per graduating candidate, out of a maximum of 45

• Global average: 30.9 points - the baseline against which all ranked schools are measured

• Minimum cohort: 20 students for the main table; smaller cohorts listed separately

• Data source: results submitted by schools, cross-referenced with IB Organisation published data

• Status: the 2026 table is provisional and subject to change following re-marking requests

What JBCN's Position in the Top 30 Means

Joint #23 in the World — What That Score Represents

JBCN's 39.0 average places it 8.1 points above the global IB average of 30.9. A score in the high 30s opens the most selective universities in the world. JBCN graduates in the Class of 2026 received offers from MIT, Stanford, Cornell, Johns Hopkins, University of Cambridge, LSE, and Imperial College London — universities that use IB scores as part of their admissions criteria.

Two Campuses in the Global Top 25

Very few school groups in the world place two campuses in the global top 25 simultaneously. JBCN Parel with a cohort of 40 learners and JBCN Oshiwara with a cohort of 30 both achieve 39.0. The same standard of teaching, the same EduCreative philosophy, and the same counselling approach produce top-25 results at two different locations in Mumbai.

Zara Kanchwala: 45/45

Within the cohort average, individual results go significantly higher. Zara Kanchwala of JBCN Oshiwara earned a perfect score of 45/45 in the Class of 2026, placing her in the top 0.5% of IB learners globally. The 39.0 group average is the floor, not the ceiling.

What Produces These Results

• Examiner-level faculty: nearly 50% of JBCN educators are official IB and Cambridge examiners and curriculum consultants

• 100% IBDP pass rate: every JBCN learner who entered the IB Diploma has earned the full diploma, sustained across multiple years

• Counselling from Grade 7: subject combinations are planned against university entry requirements four years before the diploma begins

• EduCreative philosophy: inquiry, research, and application built into the method of instruction — exactly what IB assessments reward
