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.
