When searching for a professional genealogist to work with, have you noticed the letters many genealogists use after their names? AG^®, AGL^TM, CG^®, CGL^®… Ever wondered what they mean? Or if they mean anything at all?

There is no licensing board for genealogists, no state certification, no required process before someone can charge for services. Genealogical skill, experience, and work products are measured differently.

The field of professional genealogy has two rigorous, independent credentialing processes that can increase your confidence when selecting a professional to work with.

Credentials Mean Something

There are two major credentialing bodies in the United States issuing post nominals representing their organization. The Board for Certification of Genealogists (BCG) awards the Certified Genealogist^® (CG^®) credential, and the International Commission for the Accreditation of Professional Genealogists (ICAPGen℠) awards the Accredited Genealogist^® (AG^®) credential. Both are nonprofits. Both require renewal every five years. Both hold members to written codes of ethics. Knowledge of the underlying process for each credentialing board gives a deeper understanding of what the credential represents for you.

The CG: Portfolio Evaluation

BCG’s mission is to increase public confidence in genealogy by promoting competence and ethics with uniform standards. Certified Genealogist associates have demonstrated competence in research methodology, analysis, and clear written communication.

To earn the credential, applicants submit a portfolio of client-quality research work. It is evaluated independently and anonymously by at least three BCG-credentialed judges against rubrics grounded in the Genealogical Proof Standard (GPS) and the organization’s published Genealogy Standards. BCG also offers two optional add-on credentials for CG associates: the Certified Genealogical Lecturer^® (CGL^®) and the Certified Genetic Genealogist^® (CGG^®).

The AG: Tested Regional Expertise

ICAPGen’s mission is to advance family history and genealogy work by testing competence in genealogical research, writing skills, and regional expertise. Accreditation is offered for many United States and international regions, with more to come. Candidates are tested in depth on methodology, record types, analysis, clear written communication, and regional topics important to genealogical research.

To earn the AG credential, applicants submit a professional, thoroughly researched and documented written report and take three written examinations. Reports and exams are anonymized and evaluated independently by at least three AG professionals against rubrics grounded in the GPS and accepted genealogical standards. The final step is an oral review with a panel of credentialed AG professionals to further evaluate expertise and professional readiness.

The AG credential is region-specific, and the process allows researchers to hold credentials in multiple regions. ICAPGen also offers an optional add-on credential for AG professionals: the Accredited Genealogist Lecturer™ (AGL™).

Other Letters You May See

Membership in the Association of Professional Genealogists (APG) is a professional affiliation, not a credentialing board. Membership demonstrates community engagement and agreement with a code of ethics, but it is not evidence that a researcher’s work has been evaluated.

Experience matters. A researcher who has attended many conferences, published widely, or taught extensively may be highly capable without a CG or AG. Credentials are a reliable, independent sign that a neutral body of peers has examined a researcher’s work against documented professional standards.

Questions Worth Asking Before You Hire

Do they hold a current CG or AG? BCG and ICAPGen both maintain public directories you can check in under a minute.

How do they handle research in unfamiliar territory? No genealogist is a specialist or even experienced in every location or type of research. Ask how their specialization or experience might apply to your family.

Can they show you a sample report? A professional should be able to produce a sample of the written work they deliver to clients. Conclusions without citations, or confident claims without explanation, are red flags regardless of the letters after a name.

Credentials tell you an independent evaluation of their knowledge has taken place. A sample report tells you what the work looks like. Together, they give you clear information as you decide.
