Not really. If the child has a good academic and discipline record and if the parent pays school taxes to the district of the school they attend, it would be ok. I also don't mind tuitioning as long as the tuition is equal to what residents in that district pay in school taxes and the student meets the previous restrictions on performance and behavior.
Personally, I hate the way I see things done. Students with exceptional IQs should not have to attend a school catering to "normals". There should be at least two options in schools in any areas, exceptional potential and all others. If possible, three would be best. Non-exceptional-non-college bound, Non-exceptional-college bound and Exceptional. This would of course require the way school districts, at least in Texas, get their money and would require a more centralized control statewide instead of independent districts.
A forth option could also be added, "IQ doesn't matter your parents are liberal/leftist idiots and if you follow them you will end up a low wage moron anyway" could be the 4th type of school available. Basically, children of Liberals/leftist would be required to attend inner-city welfare district schools so that they will learn the life skills need for where they will likely end up.
