For anyone interested in reading about such things, I submitted my Stage One application for Registration at the end of January 2012.
Stage One is about offering evidence that you had operated as an architect for a minimum of seven years after getting qualified.
It was as eloquent a reply as I could think of to the letter requesting me to offer an undertaking not to use the Title.
This was the latest stage in a three year process of research, negotiating, assembling, study, and meetings.
There was no delay the part of the RIAI - they confirmed acceptance and pointed me towards Stage Two.
For the avoidance of doubt and to encourage others who may be dithering, here is the Introduction.
ROUTE C ADMISSION TO RIAI MEMBERSHIP AND TO THE RIAI REGISTER FOR ARCHITECTS
The purpose of this process is to allow the applicant to demonstrate that he or she has a degree, diploma or other
qualification in architecture prescribed under the Building Control Act, and seven or more years of post-graduate
experience of performing duties commensurate with those of an architect, such as has equipped him/her with the
knowledge, skills and competence necessary for independent practice as an architect in Ireland.
Stage 1. Submission of Application supported by documentation demonstrating that the Applicant’s academic
qualifications and duration of post-graduate experience meet the eligibility criteria. If this requirement is met the Applicant
proceeds to Stage 2.
Stage 2. Submission of an Account of Practical Experience and a Self-Assessment of Professional Practice Knowledge,
Skills and Competence acquired by the applicant, with supporting documentation.
Stage 3. Interview. In certain cases, where the Assessors judge that the Self-Assessment and Documentary Evidence
clearly demonstrate that the Applicant has had sufficient post-graduate experience of performing duties commensurate
with those of an architect to acquire the necessary knowledge, skills and competence, the Interview may be dispensed
That's the "easy" bit - now comes the hard part!
