Genealogical Proof Standard

The Genealogical Proof Standard (GPS) is a guideline for establishing the reliability ("proof") of a genealogical conclusion with reasonable certainty.^[1] It is important within the genealogical community for clearly communicating the quality of research performed, such as by a professional genealogist. It is also useful for helping new genealogists understand what is needed to do high-quality research, how to identify an individual and establish family relationships.^[2]

It has five elements:

• reasonably exhaustive research;
• complete and accurate source citations;
• analysis and correlation of the collected information;
• resolution of any conflicting evidence; and
• a soundly reasoned, coherently written conclusion.^[3]
