The main thing is to identify these kids early then provide them the opportunities they need. Then educate the parents.
The grade skip option is the best route for districts with little money as it costs very little to do it.
The IOWA scale is fine, but its used AFTER the kids are identified.
The better route would be to get parents to fill out a series of questions based on Ruf ( may have to do an oral interview ), and then from there do interviews of the kids - all in Kindergarten. And then from there track the kids.
I would imagine that most if the identification and testing could be done by volunteers as a another way to save money.
