You can get to the by state info here:
http://www.davidsongifted.org/db/Being at a partial gifted magnet, the principal explained that not every teacher has certification because the certification program is $2500 and there is no pool of funding through the district or state to reimburse them and there is no bump in pay for being certified. But the coordinators all are certified, I believe that is a requirement here.
In mentioning DS's asynchrony in handwriting to the coordinator, she responded to not worry that is very common. Somehow that alone seemed like solid credentials for me.
