I'm skeptical about gatekeepers and skeptical about the value of GIS certification. It seems so medieval. Hopefully somebody will watch and make sure they don't violate their own code of ethics by lobbying city, county, and state governments to ordain preference for, or requirement of, certification.
I've paid $40 to the Red Cross for education and certification in child CPR, but for that money I received quality training from an experienced nurse. I exchanged money for skills, plus a piece of paper attesting to those skills.
