Course rating and slope, explained

The two numbers on every scorecard, what they mean, and why they change your handicap.

Updated October 20, 2026

Short answer

Course rating is the score a scratch golfer is expected to shoot from a set of tees, like 71.3.

Slope rating measures how much harder the course plays for an average golfer than for a scratch golfer. It runs from 55 to 155, and 113 is standard.

Course rating: the expert's par

Par tells you how many strokes a hole is designed to take. Course rating tells you what a scratch golfer, someone with a 0 handicap, would really shoot from those tees in normal conditions. A par-72 course might be rated 69.6 from the forward tees and 72.2 from the back.

Slope: how hard it is for the rest of us

Two courses can have the same course rating but play very differently for an average golfer. Long carries over water, thick rough, and fast greens hurt a 20-handicapper far more than a scratch player. Slope captures that extra difficulty.

A real example

Here are three sets of tees at Delray Beach Golf Club, par 72 from each:

TeesYardsCourse ratingSlope
Gold6,90772.2119
Blue6,38069.6111
Green5,78867.0110

A 90 from the Gold tees is a better round than a 90 from the Green tees, and the ratings are how a handicap gives you credit for that.

Why they matter for your handicap

Every round's differential uses both numbers:

Differential = (113 ÷ Slope) × (Adjusted score − Course rating)

They also decide how many strokes you get on a given day:

Course handicap = Index × (Slope ÷ 113) + (Course rating − Par)

So the same golfer gets more strokes on a high-slope course and fewer on an easy one. That's what lets golfers of different abilities play fair matches anywhere.

Where to find them

Courses are re-rated at least every 10 years, and new courses within 5. If your scorecard is old, the numbers may have changed.
