Go to the link above; it and pages nearby should give you a list of all the CAA approved schools for the issue of JAA licenses. Since CAA is the ONLY JAA member approving out of europe training this is effectively the JAA list.
As a word of advice; where ever you go get them to send you a copy of their JAA approval notice! They maybe JAA approved for PPL but not anything else - they could stilladvertsie themselves as JAA approved!!
Good luck!!
