The slope rating of the golf course is a measure of its difficulty for a bogey golfer. The term stems from the possibility that when playing in more difficult programs, players score will increase faster than their handicaps predicted. The "slope rating" of a course therefore predicts the increase. The term was invented by the US Golf Association.

Definition of USGA
The USGA states that the slope rate is a sign indicating the relative difficulty measurement of the course for players who are not scratch golfers compared to the USGA course rank (eg, compared to the course difficulty for scratch golfers). The tilt rating is calculated from the difference between a bogey rating and a USGA course rating. The default playground golf course has a slope rating of 113, and the slope rate ranges from a minimum of 55 (very easy) to a maximum of 155 (very difficult).
The USGA slope rating of the golf course is a sign that describes the size of the difficulty for a bogey golfer relative to the scratch golfer on a particular set of tees. This illustrates the fact that when playing on a more difficult field, scores of players with high defects will increase faster than golfers with low defects. The slope rating of a tee set predicts a straight-line increase in an anticipated score versus a USGA course defect, as in the slope of the mathematical chart.
The tilt rating is calculated from the difference in the bogey course assessment and the initial course grade, better known as the course ranking. This difference is multiplied by 5,381 for a male slope rating or 4,240 for a female slope rating. Course ratings (scourges and scratches) are determined by the assessors only, who measure and record over 460 numbers on the course assessment form for each set of tees.

Historical slope ranking
In 1977, then Commanding Lieutenant Dean Knuth, a graduate student at the Naval Graduate School, proposed an improved course ranking system that involved a numerical rating of ten characteristics for each hole. These ratings together with the weighted factors for each of these characteristics provide an adjustment for distance assessment for the course. The method used several elements of decision theory and is intended to be a quantitative, systematic approach to judgment only. That is the basis for the current ASGA Rating Rating System. When he was stationed in Norfolk, Virginia, he developed a method for Bogey Rating. Together, the Bogey Rating and Course Rank yields the Slope Rank of the golf course. Knuth served as Senior Director of the USGA Senior Society for 16 years, starting in 1981.
In 1982, the Colorado Golf Association rated all its courses using a new procedure, under the leadership of HRT Dr. Byron Williamson. In 1983, Colorado tested the Slope System with positive results. The other five states joined Colorado in the exam during 1984, and others followed in the following years. Since January 1, 1990, every golf association in the United States who assesses the golf course, uses the USGA Course Ranking System. In 1994, the foreign golf associates licensed to use the system were: Scotland, Canada, Ireland, Wales, Sweden, Denmark, Germany, France, Bermuda, Republic of China, Costa Rica, France, Hong Kong, India, Jamaica, Korea, Malaysia , Mexico, the Netherlands, Indonesia, Singapore, and the Philippines. Australia is the last country to adopt the Tilt System of course rating. It continues to grow in use around the world. The common worldwide use possibilities of the USGA Rating Rating and Tilt Rating system are being discussed as interest grows in 2011.
