The Government initiative, known as Modernising Medical Careers (MMC), is designed to cut the length of training and to create fast-track sub-consultants.
But many doctors, at all levels of training, have said they do not believe that the scheme in its current form will "contribute to improved patient care or produce better doctors".
They are also concerned that the process used to implement the new system – the Medical Training Application Service – is "fatally flawed".
The meeting follows the setting up of a website, www.northern
irishmedics.org.uk, by doctors to lobby for Northern Ireland to pull out of MMC unless a national workable solution can be found.
Last night's meeting was also to be attended by representatives from various political parties.
The organisers were to call for the MMC process to be stopped immediately in Northern Ireland, "before any more damage is done, until the proposed process can be properly evaluated and tested".
