My kids go to Highmeadow Common Campus. Unfortunately they have already drawn the lottery for the next academic year. I believe it is the best Farmington Public school for all around gifted children. One of mine excelled in math and reading and was sometimes bored in K at our home school (even though our home school is a very good one). My other is not as advanced but through sibling preference is also now at HCC and the K program is terrific for kids of all levels. HCC attracts and is geared for children like mine and they are doing quite well there.
If you do school of choice this year, I don't know if you can still enter the HCC lottery in the future. You'd have to check on that. But that is what I would recommend. A lot depends on the teacher, too.
Best of luck to you.
