I don't exactly get the lady who says she's uncomfortable with her 8 and 6-year-olds going to a school with 12th graders.
On the one hand, I can see her point with a regular-sized public school.
On the other hand, kids go to private schools that run K-12 on a regular basis. My kids go to such a school. Granted, those schools are somewhat smaller.
I wonder if Missouri has a voucher program and, if it does, how many black parents are going to opt to use it.
