Certified Genealogists
There is a growing field in technical schools and universities to receive in genealogical studies. This degree/diploma simply states that you have completed a set of classes geared toward genealogy. This is not the same thing as being a board certified genealogist.
A board certified genealogist must first fill out an application, complete a portfolio that shows their work and abilities that they turn in with their final application, and pay a yearly maintenance fee. Even though a formal education is not mandatory with the quality of standards rising, many find the formal training of a university helpful.
