As we progress in family history research, we learn about research practices and standards that guide genealogists in improving research methods.

The Board for Certification of Genealogists hosts a website with skill building work samples following the BCG approved Standards where we read:

  • "Proof is a fundamental concept in genealogy. In order to merit confidence, each conclusion about an ancestor must have sufficient credibility to be accepted as "proved." Acceptable conclusions, therefore, meet the Genealogical Proof Standard (GPS). "
  • The GPS reflects a change from the term "Preponderance of the Evidence," used earlier to describe the high standard of proof BCG had always promoted. (For further information about this topic, click here for information on BCG's decision and here for a detailed article on this subject.) Case studies in national genealogical journals, such as the National Genealogical Society Quarterly and The American Genealogist, illustrate the GPS."

The National Genealogical Society (US) looks at standards of excellence in several areas. "NGS welcomes links to its Standards and Guidelines on other websites or their reproduction by others, as permitted by the copyright notice. However, such support from others does not assure that their websites or works conform to the recommended Standards or Guidelines."

Between 1998 and 2000, the Lexicon Working Group produced documents and findings about the GenTech Genealogical Model. By a merger in 2002, GenTech became known as NGS GenTech, division of The National Genealogical Society (NGS). Particular documents from 1998 and 2000 by the Lexicon Working Group are available from the NGS Internet site. The documents available from NGS GenTech include a 101 page model description/ discussion and, separately, two diagrams of the model. The diagrams are a representation of the GenTech (a) data model and (b) process "map." The Lexicon/GenTech materials can be downloaded (pdf, MS Word 97 and Visio format).  See the Build a Better Gedcom blog page "GenTech" for additional references.
