Navigating the Professional Genealogy Landscape: A Guide to Organizations and Credentials

Tracing your family history often begins as a personal hobby, but for many it evolves into a professional pursuit. As the industry has grown, so has the framework of genealogy organizations that support it. For someone looking to hire a researcher or enter the field, the alphabet soup of acronyms—APG, BCG, ICAPGen, NGS—can be overwhelming.

With so many different groups claiming to represent the field, how can a person know which ones guarantee high-quality research? Understanding these organizations is more than just learning names; it is about understanding the standards that protect the integrity of family history research.

Why Multiple Organizations Exist

The world of genealogy is vast, covering everything from local record preservation and DNA analysis to complex legal heirship cases. No single entity could effectively govern every aspect of the field. Instead, different organizations have evolved to serve specific niches:

• Professional trade groups: Focus on the business and ethics of being a genealogist
• Educational groups: Focus on teaching researchers how to improve their skills
• Credentialing bodies: Focus on testing and verifying a researcher’s competence

By having distinct organizations, the field ensures a system of checks and balances. One group might teach you how to research, while another tests whether you learned the material to a professional standard.

Membership vs. Credentials: The Critical Distinction

Before diving into the specific groups, it is vital to clarify a common point of confusion: the difference between membership and credentials.

Membership

Anyone can join a membership-based organization by paying annual dues. Membership organizations do not require a test of skill or a review of work samples. Being a member of a prestigious group shows the person has an interest in the field and provides access to the group’s resources. However, membership in a group does not provide a “seal of approval” regarding the quality of a member’s research.

Credentials (Certification, Accreditation or Degree)

Credentials must be earned. They are not granted based on a fee, but rather on a rigorous peer-review process. A credentialed genealogist has submitted their work to be evaluated by experts to prove they meet high standards of evidence, logic, and documentation.

Key takeaway: If a genealogist lists an organization on their resume, check whether they are a “member” (they paid to join) or are “board-certified/accredited” (they passed a difficult exam).

The Major Players: A Breakdown

To choose the right professional or educational path, you need to know what each major group brings to the table.

1. Association of Professional Genealogists (APG)

• Primary role: Professional trade association.
• What they do: APG focuses on the business side of genealogy. They advocate for high ethical standards and provide a directory of genealogists to help clients find researchers.
• Focus: Ethics and professionalism. All members must sign a strict Code of Ethics. While APG does not test its members’ research skills, they do provide a grievance process if a member violates their ethical agreement.

2. National Genealogical Society (NGS)

• Primary role: Education and advocacy.
• What they do: NGS is one of the largest member organizations in the United States. They provide extensive webinars, a major annual conference, and a monthly magazine.
• Focus: Education. They are a teaching organization. They help hobbyists become professionals and help professionals stay sharp. Like APG, NGS is a membership organization; joining does not mean a person is “certified.”

3. Board for Certification of Genealogists (BCG)

• Primary role: Credentialing body.
• What they do: BCG is the entity that awards the Certified Genealogist® (CG®) credential. To earn this credential, a researcher must submit a portfolio of original research, document their proof arguments, and pass a rigorous evaluation.
• Focus: Standards and testing. They set the genealogy standards used across the industry. When you see “CG” after a name, it means that person’s work has been judged and approved by their peers.

4. International Commission for the Accreditation of Professional Genealogists (ICAPGen)

• Primary role: Credentialing body.
• What they do: ICAPGen awards the Accredited Genealogist® (AG®) credential. Their process is unique because it tests a researcher’s expertise in a specific geographic region (e.g., New England, Germany, or the Mid-Atlantic).
• Focus: Regional expertise. The accreditation process involves multiple levels of testing, including a proctored exam and a research project focused on a specific area’s records and history.

5. Various Colleges and Universities

• Primary role: Education and Expertise Testing
• What they do: In order to achieve a degree in genealogy, a student takes a variety of classes and then must pass exams and/or review processes to prove expertise.
• Focus: Methodology, standards, testing.

Comparing the Organizations

Why Credentials Matter to Clients

When you hire a professional for a project—whether for a home renovation or a legal case—you look for licensing and certification. Genealogy is no different.

Because family history research involves interpreting old handwriting, navigating fragmented records, and solving complex DNA puzzles, the margin for error is high. A single mistake in identity can lead to an entire tree of “ancestors” who aren’t actually related to you.

Credentials provide three main layers of protection:

1. Objectivity: A credentialed researcher follows a standard of proof that requires exhaustive research and thoroughly analyzed evidence.¹ This prevents research shortcuts that result in errors.
2. Accountability: All research by credentialed professionals is conducted in strict accordance with the Genealogical Proof Standard (GPS). We operate under a professional code of ethics that prioritizes evidence-based conclusions and high-caliber reporting for our clients.
3. Efficiency: Experienced, credentialed researchers often work faster because they know exactly which records to check and which archives are likely to hold the answers, potentially saving the client money in the long run.

For professional firms like Legacy Tree Genealogists, aligning with these standards is a core part of the business model. By employing researchers who are either credentialed or adhere strictly to the standards set by these organizations, a firm ensures that the stories and lineages they provide are backed by solid evidence rather than guesswork.

Summary

The world of professional genealogy is supported by a network of organizations designed to educate, regulate, and certify.

• NGS and APG provide community, ethics, and education.
• BCG and ICAPGen and various colleges and universities provide rigorous testing that proves a researcher’s skill.

Whether you are a student of genealogy looking to sharpen your skills or a person looking to hire a professional genealogist, understanding these organizations can help ensure that your family history research is accurate, ethical, and built to last for generations.
