Course Rating
A course rating is a number, expressed in strokes, that shows the score a scratch golfer is expected to shoot from a specific set of tees under normal course and weather conditions.
What is a course rating?
Course rating answers one specific question: how hard does the course play for a scratch golfer? The USGA defines a scratch player as someone with a Handicap Index of 0.0. Every set of rated tees gets its own number, given to one decimal place. A rating of 72.4 means a scratch player should average about 72 strokes there in good rounds; on an easier course rated 68.9, the same player would expect to average closer to 69.
The rating exists because par alone fails to describe difficulty. Two par-72 courses can play in completely different ways, one short and open, one long and tight, and a scratch golfer’s expected score reflects that. Course rating turns difficulty into a measurable number, which is why it sits at the heart of the Handicap Index system. Every official handicap calculation worldwide uses it.
Yardage is the predominant factor, according to the USGA, but distance is not the only input. The rating team also adjusts for conditions that affect playing length, like elevation, prevailing wind on each hole, altitude, and forced lay-ups around hazards, and scores the difficulty of every bunker, water hazard near a landing zone, line of trees, and patch of rough on the course. The result is a precise, comparable score that lets a 12-handicap player size up an unfamiliar layout before teeing off.
How to read a course rating on a scorecard
Course rating appears on virtually every USGA-rated scorecard, usually printed alongside the slope rating in a format like 72.4 / 132. The decimal matters. A 71.2 and a 71.8 sit close together but produce different score differentials when handicaps are calculated.
Each set of tees has its own rating, with the back tees rating highest and forward tees lowest. Men’s and women’s ratings from the same tees can also differ. Quintero Golf Club, for example, lists its gold tees at a course rating of 72.9 with a slope of 141, and its silver tees (women’s) at a rating of 78.4 with a slope of 151. Tidewater Golf Club’s championship tees rate 73.9 with a slope of 148.
| Tees | Course rating | Slope rating |
|---|---|---|
| Quintero Golf Club, gold | 72.9 | 141 |
| Quintero Golf Club, silver (women’s) | 78.4 | 151 |
| Tidewater Golf Club, championship | 73.9 | 148 |
What goes into a course rating?
Two main factors feed the calculation: effective playing length and obstacle stroke value.
Effective playing length is the measured yardage adjusted for conditions that change how far the course actually plays. The USGA accounts for roll on the fairways, prevailing wind, elevation changes between tee and green, dogleg or forced lay-ups, and altitude. Courses above 2,000 feet play shorter because the ball flies farther in thinner air. According to Central Links Golf, every additional 55 yards of effective playing length adds roughly 0.3 strokes to the rating.
Obstacle stroke value is the team’s evaluation of 10 obstacle categories on every hole: topography, fairway width, green target, rough and recoverability, bunkers, out-of-bounds, water, trees, green surface, and a psychology factor for holes that play tougher than the numbers suggest. Each obstacle is scored from 0 (none) to 10 (extreme) based on USGA guideline tables, with values weighted by how close the obstacle sits to the landing zone.
Wikipedia notes that raters record more than 460 measurements per set of tees, and the SCGA puts it at roughly 26 evaluations for each set of tees on every hole, multiplying into thousands per course.
Course rating vs. slope rating
The two numbers appear together on every scorecard, but they measure different things. Course rating tells the scratch player how hard the course is. Slope rating tells the bogey player how much harder the course is for them, relative to the scratch player.
| Aspect | Course rating | Slope rating |
|---|---|---|
| Measures difficulty for | Scratch golfer (Handicap Index 0.0) | Bogey golfer (20.0 men, 24.0 women) |
| Expressed as | Strokes (one decimal place) | Whole number on a 55–155 scale |
| Typical value | 66–77 | 113 is the standard average |
| Role in handicap formula | Reference score for the differential | Adjusts the differential up or down |
Both are needed to calculate a Score Differential. The formula, per USGA Rules of Handicapping, is (113 ÷ Slope Rating) × (Adjusted Gross Score − Course Rating − PCC adjustment).
Course rating vs. par
Par is the target score the course architect set for each hole, based on length and assumed shot count. Course rating is the score a scratch player is realistically expected to shoot. The two are usually close, often within a stroke or two, but rarely identical.
A course rating higher than par means the course plays tougher than par suggests, often because of forced carries, narrow corridors, or extreme yardage. When the rating drops below par, the course tends to be easier, with wider fairways and softer hazards. Quintero Golf Club’s gold tees, for instance, have a course rating of 72.9 against a par of 72, meaning a scratch golfer is expected to score about 0.9 strokes worse than even par there.
Since April 2024, the World Handicap System has built the difference between course rating and par directly into the Course Handicap calculation. National Club Golfer reports that the new formula adds (Course Rating − Par) to a player’s adjusted handicap, which corrects for tees where the rating drifts further from par.
How a course rating gets set
Every rating is set by a trained team from a regional Allied Golf Association, working under USGA guidelines. The team measures the course, evaluates each hole for both a scratch and a bogey golfer, and feeds the data into the USGA Course Rating software. The software then produces the final Course Rating, along with a Bogey Rating used internally and a Slope Rating expressed on the 55–155 scale.
Per Appendix G of the Rules of Handicapping, every course must be re-rated at least once every 10 years. New courses are an exception, since they change rapidly in their first few seasons, and these get re-rated five years after the initial rating instead. Major renovations such as new tees, green resurfacing, or fresh bunker work can also trigger an earlier review.
The minimum length for a course to receive a rating was lowered in 2024 to 1,500 yards over 18 holes (750 over 9 holes), per the World Handicap System update. Most short par-3 courses now qualify.

Frequently Asked Questions
What’s a “good” course rating?
Course rating is a difficulty number, not a quality score. A higher rating means the course is harder; a lower rating means it is easier. Most 18-hole courses fall between 66 and 77.
Where can someone find a course rating?
On the scorecard, on the official rating certificate posted in the clubhouse, or in the USGA’s Course Rating and Slope Database (NCRDB), which is searchable online.
Can a course rating change?
Yes. Every rated course is re-rated at least every 10 years, and major renovations can prompt an earlier review.
What is the highest course rating in the US?
USGolfTV reports that the back tees of the Pines Course at The International in Bolton, Massachusetts, carry a course rating of 81.7 from 8,325 yards.
Is course rating the same as par?
No. Par is the target set by the course architect; course rating is the score a scratch golfer is realistically expected to shoot under normal conditions. They are often close but almost never the same.
