TeeGrade is TeeHouse's course ranking system, shown on a 0-10 scale.

It's built entirely from user-driven golfer feedback - not from editors, sponsors, or outside rankings.

TeeGrade uses one tie-aware Bradley-Terry-Davidson pairwise preference model.

1) Tier ratings: When golfers mark a course as Liked, So-so, or Disliked, those ratings set an initial prior while the model is still learning.

2) Head-to-head comparisons: When golfers compare two courses they've played, TeeHouse learns which course they actually prefer, including cases that are effectively ties.

Pairwise comparisons provide the main ranking evidence because they show which course golfers would actually choose.

Global TeeGrade is the community baseline, learned from the wider comparison network rather than a simple average or one direct matchup.

My TeeGrade starts from that same baseline and learns where your own ratings and comparisons differ from the public.

TeeGrade also estimates confidence separately from score, so early or close cases are not overstated.

For a fuller methodology explanation, visit the full TeeGrade page on the TeeHouse website.
