An Assistant Instructor course requires around 20 hours teaching, covering basic teaching principles, centre procedures and specific training in any unfamiliar equipment. Candidates are assessed on their teaching ability with beginners.

An AI can assist qualified instructors under the supervision of a Senior Instructor. Dinghy AIs can teach up to Sailing Scheme Level 2 or Youth Sailing Scheme Stage 3. Sailors can also qualify as Keelboat and Multihull AIs.

A candidate just needs one of the Sailing Scheme advanced modules and the recommendation of their RYA Training Centre Principal, which can be obtained by contacting the centre directly. The training centre sets its own minimum age (13) with the centre-specific qualification valid for five years.
