Perhaps you should ask this question in the college search and selection forum. People in this corner of CC are more likely to push you in the direction of boarding school or prep school. After all, this is the prep school forum! Sending her off to the local college might work for her, but she would also be missing out on a high school experience. I know two brothers that achieved perfect scores on their SATs in 8th grade but they continued on with high school. They both participated in lots of competitions (Mathcounts, Siemens, etc.) and they now attend Princeton and MIT. It’s all up to you and your daughter but keep in mind that she can still go to high school and be challenged at the same time outside of school. My advice is to supplement her with competitions and online courses. For math, I recommend the Art of Problem Solving. There are plenty of kids like her on that website and their classes can count as a math grade in some cases.
