I believe the proper process here in Louisiana is "purchase one or more state legislators."
In seriousness, though, even as a parent who sent his child there, I question the value of pre-K for gifted kids. The only reason mine did it is because she was excited about the idea of school, and the only reason she stayed all year was because she had a wonderful teacher who recognized how different DD was, and provided for appropriate outlets of DD's talents. If either of those conditions had not been true, we'd have been happy to keep her home. She was MORE than well-prepared for kindergarten.
Advocating for enhanced legislation at the state level is likely to run into some severe opposition. A google search for "louisiana gifted education" turns up this fairly recent news item on the first page:
Gifted, talented education programs coming under fire.
Concerned that money dedicated for disabled children is being used for gifted and talented services, the Louisiana Association of Special Education Administrators has recommended that gifted and talented education no longer be part of special education. It said these students should be placed in regular classrooms where all students are afforded the same learning opportunities.
This issue seems to bubble up from time to time.
