For those serious about genealogy the (US) Board for Certification of Genealogists offers a process whereby those who demonstrate capability to work to a standard can be recognized by that organization.
As an aid to the community the Board have regularly provided seminar presentations at US genealogy conferences covering the essentials on BCG certification. Now a video of one such seminar presented last November is available on the Board website here.
This free two-hour video seminar is in convenient segments, mostly less than 10 minutes although one is over 30 minutes. They are grouped under the headings: Preparatory Information; Parts of the Portfolio and; The Process. I reviewed a few segments which are certainly well produced.
In viewing these keep in mind that BCG is a US-based organization.
