I just want to add to @Calliemomofgirls excellent post – an admissions officer could love your kid AND feel like they wouldn’t thrive at their school for any number of reasons (and deny them for that reason.) Unlike college admissions, where there’s a little more trust in the applicant to know if they’ll really be happy in an environment, BS try really hard to admit kids who not only bring something to the community but will also extract real value from their time there. They know their community, they know what a mess a “mis-fit” can be, and they like kids and success stories.
I know it’s super hard when you’re going through it to trust the process, but it really does work out quite well for most.
