Modified Peoria System
When a player does not have an established handicap, a hole score selection system, often called the "Peoria System" is used. Under this system, a player learns their handicap after the round is completed. The Committee secretly selects a par-3 hole, a par-5 hole and four par-4 holes from an 18-hole course. The par-4s should be representative in length and difficulty with two chosen from the front nine and two from the back nine.
A modified Peoria handicap then is calculated by adding the player's strokes over par on the six selected holes, and multiplying that number by 2.8. This will be the player's allowance to be deducted from the gross score. The maximum hole score for allowance purposes is three over par on par-3s and 4s, and four over par on par-5s.
Example: A player scores 98 for a round. The player is 11 over par on the six selected holes.
11 x 2.8 = 30.8 = 31 allowance
Net score is 98 - 31 = 67
