Although you will be fine to instruct them, they would not, in turn, be able to act as instructors, although I suppose they would then have sufficient experience to go on to do a CWA or for your centre to empoly an MIA so that they could have a "centre specific" certificate or whatever.
From what I've seen and heard of it, the CWA seems the best way to go for artificial walls, particularly as there is an add-on to instruct lead climbing on a wall (not covered by the SPA).
