Architects, engineers, builders, and home designers often wear a string of letters after their names. Letters like AIA or RA can seem impressive, but what do the letters stand for and do you pronounce them like words? Here's an explanation of why the letters are there, and then a glossary of some of the most common initialisms and acronyms.
Generally, these initials fall into three categories:
1. Membership in an Organization
In many cases, the letters are acronyms for professional associations. The letters AIA, for example, stand for the American Institute of Architects, the organization that helped architecture become a licensed profession in the United States. AIA members may use a variety of designations—AIA suggests that this person is a licensed architect who has paid hundreds of dollars to become a member; FAIA is an honorary title given to a select group of AIA members. An Assoc. AIA is an associate member who has been trained as an architect but does not hold a license, and Int'l Assoc. AIA include architects licensed outside the US.
Other organizations for professional architects include the Association of Licensed Architects (ALA) and the Society of American Registered Architects (SARA).
Architects may join a professional organization for networking, support, guidance, and professional growth. Often a professional organization will act as a lobbying arm to defend the interests of the group. Also, membership in an organization suggests that the architect has agreed to uphold professional standards and a code of ethics.
However, a licensed architect who does not belong to an organization such as the AIA may still be well-trained, highly experienced, and ethical. Membership dues are expensive, and some architects opt not to join. Sometimes only the principals of a firm become members.
2. Letters That Show Education
Many architects also teach, so you may see academic degrees after their names. For example, Spanish architect Santiago Calatrava earned a doctorate, which entitles him to put Ph.D. after his name. Pritzker Laureate Zaha Hadid put AA Dipl next to her name, which means she earned an Architectural Association Diploma from the prestigious AA School of Architecture in the United Kingdom. The additional letters "Hon" mean the degree is not "earned" through coursework, but is an "honorary" degree given by the institution in recognition of the person's success.
3. Letters That Show Licenses
Sometimes the letters after a professional's name indicate that the pro has passed exams or met other important requirements for licensing, certification, or accreditation. An RA, for example, is a Registered Architect. A Registered Architect has completed an internship and passed a rigorous series of examinations offered by official architectural registration boards in the United States and Canada. Members of AIA and ALA are usually RAs, but not all RAs are members of the AIA or ALA.

Glossary of Letters You Need to Know
Do you pronounce these letters like words? For this profession, the answer is usually no. Acronyms, by definition, are pronounced as words (for example, "computerized axial tomography scans" are often called CAT scans, as if they were grown kittens), but initialisms are pronounced as individual letters (for example, we say C-D for "compact disc").
