Grading & Rankings Explained

The NRAA National Grading System grades competitors from their results in Open Competitions around Australia, under the grading rules in the NRAA Standard Shooting Rules (SSRs). A competitor’s grade appears on this site once their results have been entered through the NRAA Online Prize Meeting Program (OPMP). Grading for shooters who only shoot in club competitions is the responsibility of their club, under the club grading rules in the SSRs.

The sections below are generated from the calculations this site runs, so they stay up to date when those calculations change.

The Online Prize Meeting Program (OPMP)

The OPMP can run any Open Competition, from a one-day prize meeting to a multi-day Kings series, and it is how results reach the National Grading System. Organisers can run their competition live in the OPMP, entering scores as the cards come in from the ranges, or arrange for the final results to be entered after the event. Entering each shot, rather than just the range total, lets the program do countbacks automatically.

Once results are entered they feed the grades and rankings on this site. To use the OPMP for a competition, contact the NRAA or your State Association well before the event to arrange access and help with setting it up.

How grades are calculated

  1. Grades are calculated from graded matches (the aggregates each competition nominates for grading) in individual competitions from the last 2 years. Team events and scores of zero are not counted.
  2. Each result is turned into a percentage of the highest score in that match for the discipline, across all grades. Centres count as fractions of a point, so a higher centre count gives a slightly higher percentage.
  3. A shooter's grading percentage is the average of their 8 most recent results in the discipline (fewer if they have not shot that many).
  4. The grade is the highest grade whose threshold that average reaches:
F Standard
A 94.5% and above
B Below 94.5%
Target Rifle
A 96.5% and above
B 94% and above, below 96.5%
C Below 94%
WA Division System
Div 1 ( WA) 98% and above
Div 2 (WA) 96.6% and above, below 98%
Div 3 (WA) 93.1% and above, below 96.6%
Div 4 (WA) 81% and above, below 93.1%

Disciplines not shown here have a single grade.

Grades are recalculated every night, so results entered today show in grades from tomorrow morning. A shooter has a grade from their first graded result, but appears on National A Grades and National B and C Grades once they have at least 5 results counted. Those pages list the top shooters in each grade by grading percentage.

Promotion of B and C Grade winners

Under SSR rule 4.5.1.1, a competitor who wins their Grade in the leadup or the Kings at a State or National Kings meeting moves up to the next Grade 14 days after the win, for the rest of that grading year plus a further twelve months. Promotions are confirmed by the NRAA Grading Officer and listed on B and C Grade Winners.

How the OZFClass Ranking is calculated

The OZFClass Ranking recognises recent success at Kings level, and commitment to attending Kings meetings around Australia. It follows the algorithm developed for ozfclass.com: the fullbore rankings first published by Bert Bowden in 2002, as revised by Alan Fraser in 2013.

  1. Points are awarded to placegetters in the leadup and the Kings match at each Kings meeting, in Target Rifle, F Open, F Standard, F/TR, Sporter Production, Sporter Open.
  2. All grades in a discipline are pooled to work out placings. Ties within a grade keep their recorded placing; ties between grades are broken by countback from the last shot.
  3. The points for each place, and how many places score, grow with the size of the field (see the table on the OZFClass Ranking page). The field is the number of shooters in the discipline with a non-zero score at every range of that match that their discipline shot, so the leadup and the Kings each have their own field.
  4. The Kings match earns the full points. The leadup earns two thirds of the points for its own field.
  5. Points hold their full value for 30 days after the event, then decay evenly to nothing at 1100 days (about three years).
  6. A shooter's ranking points are the sum of their best 5 current amounts in the discipline. The OZFClass Ranking page lists the top 40 in each discipline.

Rankings are a guide to recent achievement, not a definitive measure of ability: some very capable shooters attend few Kings meetings because of where they live or their circumstances. They are a reasonable guide for shooters who attend two or three Kings meetings a year.

How The Emms Rankings are calculated

The Emms Rankings rank Target Rifle A Grade shooters on their Kings results only.

  1. Each Kings Prize is worth the number of A Grade entries (A Grade shooters with a score in the Kings match).
  2. The A Grade winner earns that many points, second place half as many, third a third, and so on down to 1 point for the last place: with 50 entries, 50, 25, 16.667 ... 1.
  3. Points decay daily from the event, reaching zero after 1095 days (three years).
  4. A shooter's ranking is the sum of all their current points. The page lists the top 40.
