The 2020 World Junior Ice Hockey Championship Division I consisted of two tiered groups of six teams each: the second-tier Division I A and the third-tier Division I B. For each tier's tournament, the first-placed team was promoted to a higher division, while the last-placed team was relegated to a lower division.
To be eligible as a junior player in these tournaments, a player couldn't be born earlier than 2000.
