Ascend is a small not-for-profit IB World School in BKC, founded in 2011 by the Kasegaon Education Society with the University Child Development School in Seattle. Around 350 to 400 students from age 3 to 18 across PYP, MYP and Diploma on a 2.5 acre campus.

The school sits in Government Colony, Bandra East, walking distance from the BKC business park. Tuition runs around INR 8 to 10 lakh in the lower grades up to roughly INR 20 lakh in the Diploma. Facilities include a 25 metre rooftop pool, science labs, music and art studios, and outdoor sports on-site.

Parents praise small classes, individual attention, and a curriculum tailored to different learning styles. EducationWorld has ranked Ascend highly for individual attention and infrastructure relative to its size. The flip side is the small cohort: Diploma subject options are narrower than at DAIS or ASB, and staff turnover surfaces in employee feedback. Best fit for families wanting full-IB continuity in a small-school setting, willing to trade scale for personal attention.


Annual fees

Year level Age Fee
Pre-Nursery to Grade 5 (IB PYP) 3 ₹800,000
Grade 6 to Grade 10 (IB MYP) 11 ₹900,000
Grade 11 to Grade 12 (IB Diploma) 16 ₹1,000,000


  • Teachers rank Ascend among the three Mumbai schools that pay competitively, alongside the American School of Bombay and Oberoi International. The same teachers describe the school as small, IB-driven and student-centred, with one teacher explicitly recommending it for learner agency.
  • Local Mumbai parents cluster around ratings of 3.6 across small samples (around 11 to 27 reviews), with positive notes on small class sizes, individual attention, and the IB continuum, plus consistent praise for facilities in BKC.
  • One parent pushes back on rankings that omit Ascend, noting it is IB, has a long waiting list, costs less than the top tier and has only around 40 students per year. The parent framed it as a hidden alternative to the most expensive IB schools.
  • An RTE compliance dispute in 2020 surfaces in news coverage, where the school did not respond to ward-level officer notices on a lottery-allocated child. The episode is the most concrete negative signal in public material.
  • The school is consistently positioned as small and selective rather than large or marquee, with parents who choose it doing so on individualised pedagogy and 1:12 ratios.

Positives

  • Tier and pay. Reddit teacher threads place it among the three best-paying Mumbai schools alongside ASB and Oberoi.
  • Pedagogy and scale. Described as very small, student-centred, with strong learner agency under the IB programme.
  • Hidden alternative. Reddit Mumbai posters frame it as a quieter IB option with a waiting list, below top-tier fees.

Considerations

  • Parent ratings. Aggregator scores sit 3.6 to 4.0 across small samples; positive on individual attention and BKC facilities.
  • RTE compliance dispute. 2020 case where the school reportedly did not respond to ward-level officer notices on a lottery-allocated child.
