Astronomy · Expected
HBCSE · Classes 8–12 · 2026–27 window: Late Jan / early Feb 2027 (expected)
Stage two in Astronomy — physics-and-maths-heavy, leading to the IOAA pathway.
The 2025-26 INAO ran on 31 January morning. Younger students can reach INAO via NSEJS as well as NSEA. Expect the 2026-27 date around the same window.
Students of Classes 8–12. Subject focus: Astronomy. As with any olympiad, the best candidates are children who voluntarily enjoy the subject — an olympiad should stretch curiosity, not manufacture pressure.
Official information and registration: olympiads.hbcse.tifr.res.in. Always verify the current date, fee and eligibility on the organiser's own site before paying — organisers occasionally shift windows, and this page is a directory entry, not the organiser.
