Districts are required to have a program to identify using mutiple measures and they are required to "consider" the NAGC's Program Standards. The state provides no guidelines on what measures districts could use. They also don't give much in the way of guidelines on what they mean by "consider." I was a member of a Board of Education that decided that they "considered" these standards and felt they didn't have to do anything beyond that.
