International Earth Science Olympiad (IESO): 2025 IP Math & Physics Guide

Q: What does International Earth Science Olympiad (IESO): 2025 IP Math & Physics Guide cover?
A: Why the Earth-science Olympiad is more than “another CCA badge”, how its data-heavy papers dovetail with IP Maths and Physics.

TL;DR
The International Earth Science Olympiad (IESO), under the International Geoscience Education Organisation (IGEO), is one of the International Science Olympiads. Delegations are commonly described as up to four students plus two mentors per country (see the statutes for current participation rules).
IESO’s core modules often include a Data Mining Test and an Earth Science Project, and some editions include team field investigations-so spreadsheet fluency and collaborative research habits transfer directly to school science work.
Host cities, dates, and module details change year to year: use the official IESO portal and the host-year site for the latest confirmed schedule.

Status: IESO official portal, 2025 host portal, statutes (host portal copy), and IGEO medal archive checked 2026-01-26 - treat host-year dates and module formats as year-specific; always confirm with the official IESO/host pages before planning training or travel.

Ground the geophysics and data-handling practice in your weekly work by following the drills in our IP Physics tuition hub-the same LINEST, waves, and field modules power both IESO prep and school assessments.

Registration quick answer (Singapore): Students don’t enter IESO directly. Countries send national teams via their earth science olympiad. See the IESO site for current statutes and hosts: https://www.ieso-info.org/
