Higher Education

Explore the cutting-edge field of Investigative Genetic Genealogy through higher education at two distinguished institutions. Currently, specialized programs are offered exclusively at the University of New Haven and Ramapo College of New Jersey.

  • The University of New Haven offers a Graduate Certificate in Forensic Genetic Genealogy. This 10-month, fully online program covers advanced DNA testing methods, genealogical research, and practical experience, providing an unparalleled opportunity to delve into this next generation of forensic investigations.
  • Ramapo College of New Jersey offers an Investigative Genetic Genealogy (IGG) Certificate Program, an entry-level course focusing on the practical application of IGG in investigative cases. This hands-on program teaches students to work an IGG case from start to finish, including communication with investigating agencies and forensic DNA labs, all while maintaining strict privacy and security practices. Uniquely, students have the opportunity to apply their skills to a real, unsolved case involving unidentified human remains.


Currently there are no formal accreditation opportunities specifically for IGG. However, the urgent need for ethical standards and proficiency testing in this field is being addressed by the Investigative Genetic Genealogy Accreditation Board (IGGAB). They are actively developing professional standards and an examination process that will enable practitioners to become an Accredited Investigative Genetic Genealogist (AIGG). This new accreditation, currently in development, aims to build public trust, ensure proficiency and ethics, and provide accountability within the field of IGG.
