My kids went to public school, not gifted school. More than the academics in elementary is the emotional health. If you have a school that encourages your child to learn, encourages them to be themselves, you're good. If you have a school that places a ceiling on your kid and criticizes their characteristics and any little way they are "less than", your child will be miserable and damaged for life. If your child is at DYS level, a gifted school will not be enough. So it's important that you find a nurturing environment vs an academically rigorous experience.
