There has been some debate about how 9-Hole Qualifying scores are used to affect a player’s Handicap. The following is from CONGU, the Governing body for Handicapping in England, Wales, Scotland and Ireland.

Rule 5 5.1b For a 9-hole Score A 9-hole score is scaled up to an equivalent 18-hole Score Differential for immediate use in the scoring record.

A 9-hole score is scaled up to an equivalent 18-hole Score Differential by adding net pars for the remaining holes plus one additional stroke (which is applied to the first hole not played), or 17 points in Stableford format (see Diagram 5.1b/1).

The second 9 holes used for scaling up is always the same 9 holes that have been played.

A 9-hole score is scaled up to an equivalent 18-hole Score Differential as follows and rounded to the nearest tenth, with .5 rounded upwards:

Score Differential = (113 ÷ Slope Rating) x (adjusted gross score – Course Rating – (0.5 x PCC adjustment)) Where: l

Slope Rating equals the 9-hole Slope Rating of the 9 holes played.

Adjusted gross score equals the adjusted gross score for the 9 holes played, plus net pars for the second nine holes plus one additional stroke. It is calculated using the 18-hole Course Handicap, based on the 9 holes played.

Course Rating equals the Course Rating of the 9 holes played, doubled.

50% of the playing conditions calculation (PCC) for the day is applied.

Notes: 1. For the calculation of an 18-hole Course Handicap based on the 9 holes played, see Rule 6.1a. 2. An 18-hole PCC adjustment ranges from -1.0 to +3.0 (see Rule 5.6).

Basically, your 9-hole score is used then the system assumes a net Bogey on the 10th hole and 8 Nett Pars on the remaining holes, to calculate a simulated full round. The Slope index will be that from the Front 9 which, in Virginia (White/Men), is 107 (as against the 18 hole Slope Index of 104), (Red/Ladies), is 103 (as against the 18 hole Slope Index of 105),
