Ability Ratings (AR) have been in use for South African racecourse performances since 1985.
They are produced by Raceform, and used throughout the Raceform website & publications.

The methodology and scale of Ability Ratings (AR) are directly comparable to those published in the UK by Timeform (TFR) and Racing Post (RPR).

The AR, like TFR and RPR, is expressed in pounds, rather than half kilos as is the norm with the official MR ratings published in South Africa by the NHA (formerly known as the Jockey Club).
