1. Rating of schools is best done by a reputable and impartial institution. A web search did not show any other source of this list, only this thread. Where did this list come from?
2. Time span covered 2010-2011. Don't you think it should only cover year 2010? ... 2011 has barely started. Flying schools don't have calendar school years.
3. The last quality criteria cites CAAP accreditation. PAFFS, by its nature cannot be accredited by the CAAP.
Mixing civilian and military schools in a quality survey list doesn't look like a good idea - objectives, environment and other parameters are different.
