To avoid a disproportionate impact from one or two poor holes, a limit termed “net double bogey” is established for handicap calculations. A minimum submission of 54 holes, consisting of any combination of 9 or 18-hole rounds, is recommended for a new WHS handicap to ensure a fair and accurate assessment, though handicaps can be issued based on a smaller number of scores. The USGA Course and Slope Rating system serves as the foundation for the WHS, which generally adheres to the USGA Handicap System while integrating elements from six major existing handicap systems. Beyond national assessments, a peer review process evaluates golfers from other jurisdictions to determine their eligibility for participation in elite international competitions. The aim is to create a standardized handicap system across the club, ensuring fair competition among golfers of varying skill levels.
Stroke allowances may sometimes be reduced by a set betting guide for Australians percentage in order to maintain the level playing field; this is especially common in pairs and team competitions. In handicap Stableford competitions, a player’s handicap is distributed according to predetermined hole ratings (stroke index) and strokes deducted accordingly from each hole score before calculating the points for that hole. The adjusted gross score in ‘world handicap system’ is the gross score adjusted such that the maximum on any particular hole is the number of strokes taken for a hole + the handicap allowance for that hole + 2 strokes (i.e. net double bogey). While the USGA administers its own handicapping system, the administration of handicapping systems in countries affiliated to The R&A is the responsibility of the national golf associations of those countries. While these systems share some common features, e.g. most use a common course rating system, they are not easily portable because their differences create difficulties in converting handicaps between systems. One of the first standard and equitable handicap systems was introduced by the Ladies Golf Union (LGU) in the 1890s.
It is based on Stableford scoring and has some similarities to both the CONGU system, with regards to handicap categories and adjustments, and to the USGA system, with regards to the use of course and slope ratings and calculating playing handicaps. The handicap differentials are rounded to one decimal place, and the best 10 from the last 20 submitted scores are then averaged, before being multiplied by 0.96 (the “bonus of excellence”) and truncated to one decimal place to produce the handicap index. The handicap index is not used directly for playing purposes, but used to calculate a course handicap according to the slope rating of the set of tees being used with an adjustment based on the difference between the course rating and par. The score differentials are rounded to one decimal place, and the best 8 from the last 20 submitted scores are then averaged and rounded to one decimal place to produce the handicap index. For other handicapping systems, the differentials are simply the difference between the (adjusted) gross or net scores and a specified standard rating (e.g. course rating, standard scratch score, etc.), and they are used in different ways to maintain handicaps.
Systems for handicapping
For actual play, the handicap is not directly applied; instead, it must be calculated to establish a “playing handicap” tailored to the specific course and tee set being utilized. EGA handicaps are categorized into groups and recorded to one decimal place, with Category 1 representing the lowest handicaps and Category 6 the highest (refer to the table below). To establish initial handicaps under the EGA Handicap System, only one recorded score from either a 9 or 18-hole round is needed, using the top handicap limit of 54. The European Golf Association’s EGA Handicap System assesses golfers’ abilities to facilitate fair competition in handicap events among players of diverse skills.
Handicaps are updated once every month, with current handicaps generated from a lookup table using the average of the best eight differentials from the last 16 rounds. An initial handicap of 25 is normally used as a starting point, which is then adjusted based on the submitted scores. This necessitated a few additional changes (e.g. playing handicap and differential calculations), but the system retained all other features (e.g. Adjusted Gross and no daily course rating adjustment). The system previously calculated handicaps against an adjusted Standard Rating (called Calculated Rating) but this was suspended in 2012.
Slope Rating
A couple of adjustments are then made to this total to give the player’s handicap, which is then applied to their gross score as normal. When players have completed their rounds, they apply the Peoria algorithm to their scores on the selected holes to determine their handicap for that round. Before play commences, the organisers secretly select 6 holes (in readiness for handicapping purposes later) from the course to be played. The Peoria System was designed for the handicapping of all players competing in an event such as a charity or corporate golf day.
- New handicaps require 3 18-hole scores to be submitted (or any combination of 9 and 18-hole scores totaling 54 holes played) using a “Temporary Daily Handicap” of 36 for men or 45 for women in order to calculate the necessary “sloped played to” results.
- The system is published by CONGU and administered by each of the individual unions on behalf of their members, with handicaps being managed locally by someone at each club; this person normally holds the position of competitions or handicap secretary.
- In addition to playing in qualifying competitions, golfers in Category 2 and above may also submit a number of extra day scores in order to maintain their handicap.
- Under the EGA Handicap System, initial handicaps require just a single 9 or 18-hole score recorded using the maximum handicap of 54.
Maximum hole score
The number of strokes taken on each hole is adjusted to maximum of double the par of the hole before adding up the scores; adjustments were previously 2 over par for men and 3 over par for women. The organization was tasked with creating a handicapping system that would be equitable to golfers of varying ability, and as a result the Standard Scratch Score and Handicapping Scheme was devised. The handicap index is not used directly for playing purposes, but used to calculate a course handicap according to the slope rating of the set of tees being used. If there are at least 5 but fewer than 20 qualifying scores available, the handicap index is calculated using a set number or differentials according to how many scores are available. Initial handicaps are calculated from a minimum of five scores using ESC adjustments based on the course handicap corresponding to a handicap index of 36.4 for men or 40.4 for women. A USGA handicap is calculated with a specific arithmetic formula that approximates how many strokes above or below par a player might be able to play, based on the ten best scores of their last twenty rounds.
This is done by means of “soft” and “hard” caps based on the lowest index during the previous 365 days; the soft cap reduces increases above 3.0 to 50%, and the hard cap limits increases to 5.0. For competitions, the unrounded course handicap is converted to a playing handicap by applying a handicap allowance, dependent on the format of play. 9 hole scores may be submitted for WHS calculation, with an expected score for the player’s handicap index is used to produce an equivalent 18-hole score differential. Ongoing handicaps are based on the average of the best 8 differentials, but with an “anchor” to prevent rapid increases that would not necessarily reflect the player’s true potential. For players with current handicaps, their handicap records in the old systems will be used to produce WHS handicaps; the expectation is that most players will at most see a difference of one or two strokes, if any. For example, 8 differentials (like the Golf Australia system) are used after net double bogey adjustments (like the CONGU and EGA systems) for handicap calculations, and the WHS course/playing handicap includes a course rating adjustment (like the EGA system).
During the late 19th century, taking the difference between the average of a golfer’s best three scores during the year and par became the most widely used method of handicapping in England and Scotland. According to The Golfer’s Manual by Henry Brougham Farnie, examples of agreed terms included “third-one” (one stroke every three holes), “half-one” (one stroke every two holes), “one more” (a stroke a hole) and “two more” (two strokes a hole). The number of strokes to be given and the holes on which they would be in effect was negotiated between competing golfers prior to the start of play.
Features of handicapping systems
Recognizing the lack of consideration for different playing difficulties among various abilities, the USGA initiated efforts in 1979 to tackle this challenge by forming the Handicap Research Team. In 1974, the adoption of Equitable Stroke Control aimed to mitigate the influence of exceptionally high individual hole scores on handicap calculations. Until 1967, course ratings were rounded to whole numbers, after which they began to be assigned one decimal place. Primarily developed by Leighton Calkins, the USGA’s initial handicap system was derived from the British “three-score average,” calculating handicaps as the average of the best three scores to par from the past year.
Typically, in most significant handicap systems, a golfer does not employ their precise handicap (or handicap index) directly; instead, it is utilized for calculating their playing or course handicap. Some handicap systems allow for course ratings to be modified to reflect variations in playing conditions, such as weather and course setup, against which handicaps are evaluated and maintained. In competitions involving handicap stroke play, a golfer’s playing handicap is deducted from the total strokes taken, resulting in a net score to determine the final standings.
Two widely recognized methods for defining a maximum score per hole are Equitable Stroke Control (ESC) and net double bogey, also referred to as Stableford Points Adjustments. A maximum score is established for each hole solely for handicapping purposes, not affecting competition or match outcomes. Most popular handicap systems aim to lessen the effect of excessively high scores on any individual hole when calculating and updating handicaps. Each hole on a golf course is assigned a stroke index number, typically found on the scorecard, indicating where handicap strokes should be applied. During match play, the difference in handicaps between players (or teams) is utilized to determine how many strokes the higher handicap player receives from the lower handicap player on the lowest numbered stroke index holes during their round. The gross score for a hole (or round) refers to the total strokes taken prior to applying a golfer’s handicap, while the net score is the total after deducting any handicap allowance.
Differentials are used in both the calculation of initial handicaps and the maintenance of existing ones by averaging a specified number of the best recent differentials (e.g., the USGA system uses the best 10 out of the last 20 scores). They provide a standardized assessment of a golfer’s performance, adjusted according to the specific course being played. The lowest stroke index numbers are typically assigned to holes where higher handicappers are likely to gain an advantage, while the highest numbers are allocated to those where they are least likely to benefit. A playing handicap can also refer to the stroke allowance for a specific competition based on the playing format and is commonly calculated as a percentage of the course handicap.
