    Certification is extended by the Board for Certification of Genealogists to applicants who successfully demonstrate their ability to meet research and ethical standards. Credentials are available for two certification categories: a core research category and an optional teaching category. Certification in the research category attests to the competence of an individual’s research, analysis, kinship determination, and reporting skills. All Board associates are certified in this category. The teaching credential is an option pursued by associates who lecture and wish validation of those specialized skills. Certified Genealogist, the board’s research credential, is a registered trademark. Certified Genealogical Lecturer, the board’s teaching credential, is a service mark. The category short forms (initials)—CG and CGL—are also service marks. Individuals who have earned one or both credentials include genealogists who engage in genealogy for a living as well as family historians who value certification for personal reasons. All Board-certified genealogists, including trustees, officers, and judges, are required to submit renewal applications at five-year intervals. This reevaluation ensures that their skills are current and that the work they produce for clients, family members, readers, or audiences maintains the quality expected of modern genealogists.

    Essential Materials

    Two Board publications are essential for individuals who seek certification. They are this guide and Genealogy Standards*. The Guide explains the application process and sets out the requirements applicants must fulfill to demonstrate their skills. Genealogy Standards describes the standards against which work is measured. First codified by BCG in 2000 and revised in 2014, the standards are widely accepted criteria for sound genealogical research.

  • How do family historians know they are producing or receiving trustworthy results? This official manual from the Board of Certification for Genealogists, essentially a users' guide for family historians, provides standards for genealogical researchers to assess their own and others' work. First published in 2014, Genealogy Standards begins with the simple fact that accuracy is fundamental to genealogical research. Without it, a family’s history would be fiction. That first edition of the manual presented the standards family historians use to obtain valid results, updated, clarified, consolidated, and expanded for the 21st century, and tied more directly to the Genealogical Proof Standard. Responding to this decade’s spate of advancements in the practice of genetic genealogy, the 2019 edition modified four existing standards and added seven new standards to guide the use of DNA evidence in genealogical analysis. It also updated the Genealogist’s Code to address the protection of individuals who provide DNA samples. The revised second edition increases the clarity of DNA and privacy standards. Those standards are especially useful in the twenty-first century when many genealogists use a complex new tool—DNA testing—and trace living people more often than they did in the past.
