TAM PAX
I understand where you are coming from on this. I can't speak for ICAO or the College of course, but as you'll know ICAO itself doesn't issue licences, ICAO Standards and Recommendation are adopted by member states and it is the state which takes a view on what best suits its operation. In the UK the CAA has recently stated that we do not require the licencing of FOO or FD's instead, as they have always done, leaving it to the individual operator to ensure the competence of their operations personnel, but for the first time, they have set the standard to which this training should be conducted. In the linked FODCOM, the CAA consulted UK operators, and what has followed is that the ICAO Doc 7192 D3 provides a sound basis for the training of FOO/FD staff. I understand JAROPS1 will be amended to reflect this stance in the not too distant furture.
If you are in country that issues FOO Licences, then I would say that the GLA course will undoubtly offer you the study material to pass a formal ICAO licence exam. The College has adhered very closely to the 7192 doc in the development of this course, but has also added content for the European JAROPS environment.
Whether, ICAO will provide an endorsment the course or not is something I believe the College will persue in the furture.
If it is a licence you want, then the FAA is the most recognised, but as I said before, if you want a solid foundation in flight ops studies that will see you through your career then the ICAO course offers you much more at a reasonable price.
