In theory yes, the new training manuals for AIM from ICAO could give you a list of what you need to revise, however, they are really a framework for creating a training framework to ensure that staff knows what they should know. There will always be the following pathway:
OJT - Onboarding new recruits to the AIM Department with organizational training.
Ab-Initio AIM (similar in scope to ATC/atm Ab-initio) (ICAO 026 Course)
More OJT, Departmental exp[erience (3-6 months in each department).
Specialist Training (AIP, Chart, NOTAM, PANS-OPS, DataModelling, etc)
More OJT and experience.
Instructor Training (train the next generation).
Training manuals and Guidance are available from Canso, ICAO, and Eurocontrol. Good Guidance on the subject matter also available from the FAA.
The new training manual from ICAO is Competency Based, so it means you will need to first determine what are the competencies that each job description needs in order to perform the duties adequately.
However take this with a grain of salt as even if staff are in theory doing the same job function let's say NOTAM officer there may be for sure a core set of skills but some will be very specific to your working environment. These would include things like OJT which depends on the software you are using
I think one of the initial problems is right now with the transition there are many countries that do not know what are the skills/competencies required for certain functions like eAIP editor, AIXM DB entry, etc. This is in my opinion the most
Regional task forces may benefit from sharing information and pooling resources as usually the level of transitions is more or less similar plus we need to consider the knowledge we can share will help the community as a whole to advance.
