Genealogical Proof Standard

The Genealogical Proof Standard (GPS) is a guideline for establishing the reliability ("proof") of a genealogical conclusion with reasonable certainty. 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.

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.
