PAN AM are in fact approved to conduct all flight phases of the JAA ATPL. They are also approved to conduct the JAA CPL and ME skill tests and are currently looking at approval to conduct the I/R skill test.
I have visited the campus at FT Pierce and will recommend PAN AM as a professional and well established school.
West Michigan University is I believe the only other school able to offer JAA ATPL, and only offers residential intergrated courses. All other schools are only approved to conduct prep courses
