The first qualification is a fighting skill which is mandatory. Since 90% of a stunt performers job is fighting I think this makes sense.
The qualification requirements are detailed below.

Aikido First Kyu or brown belt equivalent from a recognised body
Wrestling - Evidence of skill and successful competition experienceOther Martial Arts (Subject to JISC's discretion) - Level immediately below black belt from the appropriate governing body which must be affiliated to the appropriate British Martial Arts Association.
These include - Kung Fu, Karate, Jujitsu, Kendo, Tai Kwondo and any form of Kick Boxing
