The AIA Fellowship program was developed to elevate those architects who have made a significant contribution to architecture and society and who have achieved a standard of excellence in the profession. Election to Fellowship not only recognizes the achievements of the architect as an individual, but also honors before the public and the profession a model architect who has made a significant contribution to architecture and society on a national level.
Here is a link to AIA’s page on Fellowship. It provides more information on how to apply for Fellowship and the requirements.
Here is a PDF of Fellowship Submission Consultants to help guide you through the process.
