Introduction
In recent years, Investigative Genetic Genealogy (IGG)—also known as Forensic Genetic Genealogy (FGG or FIGG)—has transformed criminal investigations and the identification of unknown remains. From high-profile breakthroughs like the Golden State Killer to cold cases solved by the DNA Doe Project, this field is unlocking answers once thought impossible. But with rapid growth comes the pressing need for standards, ethics, and accreditation.
The Power and Pitfalls of IGG
How IGG works
Investigators begin with DNA from a crime scene or unidentified remains. If traditional databases like CODIS (Combined DNA Index System, a national database of DNA profiles maintained by the FBI) yield no matches, genetic genealogy enters the picture. DNA profiles are uploaded to opt‑in public repositories like GEDmatch or FamilyTreeDNA, DNA Justice, and IGG practitioners trace familial relationships to generate investigative leads.
The “Golden State Killer” effect
Since that watershed case in 2018, IGG has been credited with solving dozens of cold cases. Yet, concerns about privacy, racial bias, and unregulated practice have intensified. As one Investigative Genetic Genealogist put it, “There’s no such thing as a PhD in genetic genealogy… someone getting arrested as a result of your work is about as high stakes as it gets.”
Restoring names to the nameless
The DNA Doe Project—has identified over 140 previously unidentified individuals, emphasizing ethical responsibility and sound science.
Introducing Standards: The IGGAB Initiative
What is IGGAB?
The Investigative Genetic Genealogy Accreditation Board (IGGAB) is a non‑profit dedicated to developing and administering professional standards, ethical guidelines, and an examination process for IGG practitioners—supporting public trust, competence, and accountability.
Becoming an Accredited Investigative Genetic Genealogist (AIGG)
Exam and accreditation details
IGGAB’s accreditation program enables qualified individuals to become Accredited Investigative Genetic Genealogists (AIGG) by:
- Passing a proctored, online accreditation exam (~160 questions over three hours) that covers all core competencies, including scenario-based assessments.
- Pledging adherence to IGGAB’s Standards and Code of Ethics.
Who can apply?
Applicants must be 18+, currently practicing or intending to practice IGG, whether in law enforcement, private, or volunteer roles. For the first year (through mid‑2026), no specific degrees or prior certificates are required.
Logistics and recognition
- Cost: $450 USD
- Proctoring: Live, with ID verification, environment checks, and session recording
- Results: Pass/fail notification within 72 hours
- Those who pass receive the “AIGG” post-nominal, one year of IGGA membership, and future listing in a public AIGG Registry launching later in 2025.
Maintaining credentials
Currently, reaccreditation is required every two years, based on continuing education and a fee submission.
The Road Ahead: Expectations and Impact
- Education pathways are emerging, with certificate programs offered by institutions like Ramapo College and University of New Haven—but these are complementary, not accreditation.
- As ethical frameworks and testing evolve, professionals can expect higher standards, clearer regulatory alignment, and stronger public confidence in IGG outcomes.
- IGGAB encourages jurisdictions to adopt AIGG credentials for licensing purposes, reducing the need to develop redundant standards locally.
