Global Logic and Reasoning Competition (GLRC) 2026

About the opportunity

The Global Logic and Reasoning Competition (GLRC) is an independent educational program coordinated by Edu.Harbour that tests abstract reasoning skills. Designed to engage students of all skill levels, GLRC focuses on deductive logic, probabilistic reasoning, causal reasoning, strategic reasoning, critical reading, and modeling & estimation. The competition is structured to prioritize the learning experience over pure competitiveness, utilizing experimental problem formats and real-world research topics.
