Controllers are the officials appointed to make sure that events are fair and comply with BOF Rules, and may best be thought of as technical advisers and quality controllers. Their appointment is governed by BOF Rules detailing the necessary experience. There are three grades:

Grade A: for controlling major events at the highest level, such as British Championships
Grade B: for controlling National events (old Level B)
Grade C: for controlling Regional events (old Level C) such as SWOA Galoppens

Grade B and C controllers are appointed by their regional association on the recommendation of their club.
Grade A controllers are appointed at national level on the recommendation of their regional association; they have considerable experience as competitors, organisers, planners and controllers.

All enquiries about the appointment of controllers in SWOA should be made to the Recorder of Controllers.
