The Davidson Institute offers several programs for highly gifted young people. We've covered the opening of the Davidson Academy several years ago, and the winners of the annual Davidson Fellows awards, but I also wanted to call readers' attention to the Young Scholars program, which is one of the institute's biggest efforts, now reaching 1600 young people. When kids are accepted into the program, they are eligible for consulting services which can help parents and educators decide on the best way to meet their needs. Every child is different, of course, but by the time you've studied what works and what doesn't for 1600 highly gifted kids, there are some pretty robust best practices.
You can read several success stories of different students in the program, and how those best practices worked here. You can find out how to apply here.
