CORE stands for Comprehensive On-Ice Rating Engine. It's our custom-built system for evaluating NHL players based on their total on-ice impact with a single Overall Rating. For skaters we also provide an Offensive and Defensive Rating.

All ratings are calculated using publicly available stats and advanced analytics, primarily sourced from NHL Edge and MoneyPuck. Player and team data is refreshed regularly.
