As mentioned in my first post, the AVTECH course is left wanting in many areas, but in my expereince it has value and at least I know if someone pitches up looking for a job and has completed both certificates, that that individual has,
1. An interest in learning the basics of his trade
2. Has been exposed to most of the flight ops subjects. However, the ICAO FOO/Dispatcher syllabus is much more comprehensive, goes into the appropriate level of knowledge required, and is an ICAO standard. The FAA licence is of course the other route, but is naturally focused on FAR and US met, the ICAO course is international.
