Handicapping players with no established handicap
Many times golfers participate in tournaments, but do not have an established handicap. In that case a handicap can be calculated from the posted tournament score after play is completed. There are three methods of calculating a handicap based on a golfer's posted tournament score.
Scheid System
The Scheid System is the United States Golf Association's "Callaway" style handicap system. It is a "worst holes" system for unhandicapped events, much like the Callaway System. However, unlike the Callaway system, which almost always assures the golfer with the low gross score wins the low net competition, the Scheid system is designed to give all players an equal chance to win. The system uses the following table to calculate handicaps:

Peoria System
Another alternative is to use a hole score selection system, often called the "Peoria System". With this system, the tournament committee secretly selects a par3 hole, a par5 hole and four par4 holes from an 18hole course. The par4s should be representative in difficulty with two chosen from the front nine and two from the back nine. TM calculates the handicap by adding the player's strokes over par on the six selected holes and multiplying that number by 2.8. This will become the golfer's handicap...to be deducted from his gross score. Furthermore, no more than a maximum of three over par on the par3 and par4s, and four over par on the par5 is allowed.
System 36
This system allows you to calculate handicaps based on the number of points a golfer has won. The standard formula is..
Handicap = 36  points won
How points are awarded is setup on Tournament Parameters.
