Canadian Computing Competition (CCC) International Physics Olympiad
Prestige Tier Tier 2 — Highly Competitive Tier 1 — Elite
Type Competition Olympiad
Organization Centre for Education in Mathematics and Computing (CEMC), University of Waterloo International Physics Olympiad Organization
Acceptance Rate Not publicly disclosed; appears to be high participation (designed as accessible competition) but very selective for CCO (~20 top Canadian participants) and CIW (select top female-identifying/non-binary participants) Extremely selective. Only 5 students per country advance (approximately 400-420 students total compete at IPhO from 80+ countries).
