I very much agree with this post. Based on what you’ve said, it seems like your school will be relatively unknown to many of the boarding schools to which you are applying. I would encourage you to cast a wider net, as these schools will be reluctant to use one of their spots on an untested school without a firm point of reference. Even an extremely compelling candidate (with strong SSATs) would struggle to differentiate themselves in these circumstances. Please take the advice of others on this forum and consider adding some other schools as well.
