Posting a score means entering your adjusted gross score into the USGA/WHS system so it counts toward your handicap index. You do it hole by hole or as a total, using your actual strokes after applying net double bogey max. The single most useful takeaway: post every acceptable round, including bad ones, because your index uses your 8 best of your last 20 differentials. Skip the bad rounds and your handicap will be wrong — and everyone you play with will know it.

What Counts as a Score You Can Post

I play about 60 rounds a year at my home club in the Pacific Northwest, and I post almost all of them. Under WHS rules, you post scores from any round played under the Rules of Golf on a rated course, whether it's stroke play, match play, or even a solo round in most jurisdictions. You need at least 7 holes played for a 9-hole score, and 14 holes for an 18-hole score.

What you don't post: rounds where you didn't play by the rules, rounds on unrated courses, or rounds where you picked up on more than a couple of holes. If you start a round and quit after 5 holes, that's not postable. If you play 15 holes and pick up on 3 of them, you post the holes you completed and record par plus any handicap strokes for the unfinished ones.

The score you actually enter is your adjusted gross score, not your raw score. That means any hole where you made worse than net double bogey gets capped at net double bogey. Net double bogey = par + 2 + any handicap strokes you receive on that hole. If you're a 12 handicap and you make a 9 on a par 4 where you get one stroke, your score for that hole is capped at 7 (par 4 + 2 + 1).

How Your Handicap Index Actually Gets Calculated

Once you post, the system calculates a score differential for each round. The formula is: (Adjusted Gross Score − Course Rating) × 113 ÷ Slope Rating. The 113 is the standard slope, and course rating and slope rating come from the USGA course database.

Here's a real example from my last month of golf. I shot 84 at a course with a course rating of 71.2 and a slope of 128. My differential: (84 − 71.2) × 113 ÷ 128 = 12.8 × 113 ÷ 128 = 11.3. A week later I shot 79 at a harder course, rating 73.5, slope 140. That differential: (79 − 73.5) × 113 ÷ 140 = 5.5 × 113 ÷ 140 = 4.4. Same player, very different differentials, because the courses are not equally hard.

Your handicap index is the average of your 8 best differentials out of your most recent 20 scores, multiplied by 0.96. If your 8 best differentials average 9.4, your index is 9.4 × 0.96 = 9.0. That's the number you carry to any course. To figure out your course handicap for a specific tee box, use: Handicap Index × (Slope Rating ÷ 113) + (Course Rating − Par). At my home course with a 9.0 index, slope 128, rating 71.2, par 72: 9.0 × (128 ÷ 113) + (71.2 − 72) = 9.0 × 1.133 − 0.8 = 10.2 − 0.8 = 9.4, which rounds to 9. So I play off 9 that day.

You can run these numbers yourself with our free golf handicap calculator if you want to see where your index lands before you post. I check mine after every few rounds just to see the trend.

Posting in Practice: What I Actually Do

After a round, I open the GHIN app or the club's posting terminal, select the course and tees, and enter my adjusted gross score. The app knows the rating and slope, so I don't have to look them up. If I played a 9-hole round, I post it as 9 holes and the system combines two 9-hole scores into an 18-hole differential.

A few things I've learned the hard way:

  • Post the same day if you can. Waiting a week means you forget that triple bogey on 14.
  • Adjust before you post, not after. If you made an 8 on a hole where net double bogey is 6, enter 6.
  • Post away scores too. Your handicap travels with you, and the system expects it.
  • Don't post a round where you played two balls or took mulligans. That's practice, not golf.

One more thing: your index updates every time you post, but only the most recent 20 scores count. If you post a great round, it might not even make your 8 best. That's normal. The system is designed to reflect your potential, not your average. If you want to see how a new score shifts your index before you commit it, the handicap index calculator lets you plug in a hypothetical differential.

Common Questions I Hear From Playing Partners

New players ask me this stuff constantly, so here are the answers I give on the first tee.

How many scores do I need to get a handicap?

You need a minimum of 54 holes posted, which can be three 18-hole rounds or six 9-hole rounds. Once you have 54 holes, the system calculates an initial index using a reduced number of differentials — at 3 scores it uses your lowest 1, at 4 scores your lowest 1, at 5 scores your lowest 1, and it builds from there until you have 20 scores and the full 8-of-20 kicks in.

Do I post a score if I played alone?

Under WHS, solo rounds are generally not acceptable for handicap purposes in the US, though some other jurisdictions allow them. Check your local association's rules. If you play alone and want to post, you'll need a marker or attestation in most cases.

What if I pick up on a hole?

Record your most likely score, which cannot exceed net double bogey. If you pick up on a par 4 where you get one stroke, your score for that hole is 7 at most. You still post the round as long as you completed at least 14 holes.

How often does my handicap index update?

It updates every time you post a score, or at least daily depending on your association's revision schedule. With the WHS, most indexes revise daily rather than every two weeks like the old USGA system.
