Course Rating and Slope Explained: What the Numbers Mean

What course rating and slope rating mean, how courses are rated, and how they turn your Handicap Index into a Course Handicap.

Look at any scorecard and you'll see two numbers for each set of tees: the course rating and the slope rating. They're central to the handicap system, because they let golfers compare scores on different courses fairly. But many golfers don't know what they mean. Here's a simple explanation.

Course rating

The course rating is the score a scratch golfer (handicap 0) would be expected to shoot on a course from a particular set of tees in normal conditions. It's expressed to one decimal place, such as 71.4.

  • A rating higher than par means the course is harder than average for scratch golfers.
  • A rating lower than par means it's easier.

Bogey rating

The bogey rating is the expected score of a bogey golfer, roughly a golfer with a handicap of about 20 (men) or 24 (women).

Slope rating

The slope rating shows how much more difficult the course is for a bogey golfer compared with a scratch golfer.

  • Range: 55 to 155.
  • Standard: 113.
  • Higher slope: the course is relatively harder for higher-handicap golfers, for example because of long forced carries or deep rough.

Slope is calculated from the difference between the bogey rating and the course rating.

How courses are rated

Trained rating teams from golf associations assess each set of tees, considering:

FactorExamples
Effective playing lengthDistance, elevation, roll, doglegs, altitude, prevailing wind
TopographySlopes and uneven lies
Fairway widthHow easy it is to hit the fairway
Green targetSize and how easy it is to hit
Recovery and roughHow punishing the rough is
BunkersNumber and difficulty
Penalty areas and out of boundsHow much they come into play
TreesTheir effect on play
Green surfaceSpeed and contours
Psychological effectThe combined effect of hazards

From Handicap Index to Course Handicap

Your Handicap Index is portable between courses. Your Course Handicap is the number of strokes you receive on a particular course and tees:

Course Handicap = Handicap Index × (Slope Rating ÷ 113) + (Course Rating − Par)

Example

  • Handicap Index: 15.0
  • Slope: 130
  • Course rating: 72.5
  • Par: 72

Course Handicap = 15.0 × (130 ÷ 113) + (72.5 − 72) = 17.3 + 0.5 = 17.8, which rounds to 18.

Why it matters

  • Fair competition between golfers of different abilities.
  • Fair comparison between scores on different courses and tees. Read which tees should I play?.
  • Score differentials for your handicap are calculated using course rating and slope.

Frequently asked questions

What is a good slope rating?

There's no good or bad slope; 113 is average. Higher numbers mean harder for higher-handicap golfers.

What does course rating mean?

The expected score of a scratch golfer from a set of tees.

Why is my Course Handicap different from my Handicap Index?

Your Course Handicap adjusts your Handicap Index for the difficulty of the course and tees you play.

Who rates golf courses?

Trained teams from national or regional golf associations.

The bottom line

Course rating shows how hard a course is for a scratch golfer; slope shows how much harder it is for a bogey golfer. Together, they turn your Handicap Index into a Course Handicap, making golf fair wherever you play. For more on handicaps, read how to lower your golf handicap.
