Every course gets one Greenside Index score out of 10. The score brings together the published course rankings, golfer reviews and Greenside's own assessment into a single number, so courses in different countries and on different lists can be compared directly.

Courses fall into four tiers:

Bucket List Courses worth planning a trip around.
Marquee Headline courses for any golf trip to the region.
Trip Worthy Strong courses worth adding to an itinerary.
Value Round Good, accessible golf.

A Provisional rating means the course has only limited ratings so far, and its score may move as more come in.
