text: 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.
  Peer review
  In golf clubs, peer review is usually managed by an elected Handicap Secretary who, supported by a small committee, conducts an Annual Review of the handicaps of all members and assesses ad hoc requests from individual members (usually when age or medium to long-term infirmity affects their playing ability). This gives uniformity to handicapping across their club for the setting and maintenance of handicaps with the objective of establishing fair competition between golfers of all abilities.
  At the regional level, peer review is extended to include rigorous validation of the handicap returns of low handicap golfers. This ensures that only golfers of an appropriate standard gain entry to their elite tournaments. Occasionally, golfers are excluded from the elite game as a consequence of being found to abuse the system. To a degree, these regional bodies also monitor the performance of and provide training for Handicap Secretaries at the club level.
  Nationally, the peer review is extended further to assessing golfers from external jurisdictions for their suitability for entry into their elite international events. They also play a large part in periodic reviews of the handicapping system itself to improve it for the future.
