For an 18-hole score to be acceptable for handicap purposes, a minimum of 10 holes must be played.

For a 9-hole score to be acceptable for handicap purposes, all 9 holes must be played. If a player has not played at least 9 holes, the score is not acceptable for handicap purposes.

Note:

An acceptable 9-hole score must be played over 9-holes with a current Course Rating and Slope Rating (see Rule 2.1 Acceptability of Scores).
