Sorry I wasn't clear. These were classes set aside for so-called "gifted" children. Not just classes that covered more advanced material. (Though they did.) Nearly everyone in there was really, really smart. I'm sure many kids fell through the cracks and weren't selected, but other than the odd inclusion of some musically gifted children who quickly fell behind and dropped out, we didn't really have any false positives.

That said, I totally agree that all students who can and are interested in advanced coursework ought to be able to benefit from it. I don't really understand why elementary school isn't more like college. If a 3rd-grade student reads at a 9th-grade level, but only does math at a 3rd-grade level, why compromise his experience?

And, as one who had teachers who couldn't always answer my questions, I don't really think asking one person to teach many types of subject matter is always a good idea, either.
