Excellent!!! We are very lucky to have found Open Window (and we moved across the country). The whole community - from faculty, staff, students, and parents are so welcoming, not pretentious at all (for a private school), and have a passion for seeing everyone succeed. Teachers at this school have credentials for gifted education. They are fully equipped to engage gifted learners and understand how to teach these kids. They have regular opportunities to enrich themselves in gifted ed too. Learning is indeed differentiated for each student. It's not just lip service. My daughter loves going to school everyday and she is super engaged. What she's learning is tailored to her level and interests because the teachers do well to know their students.A plus is the campus - idyllic and beautiful atop Cougar Mountain. Such a conducive space for learning!

My Kindergartener comments out-of-blue several times a week that he loves his school and said this morning he wishes he could rate it, so here we are :)I'm extremely happy with the school: It seems all the lower school specialists manage to work physical activity into their lessons, children are treated with respect and have SEL built into daily activities. The teachers and staff are highly conscientious, constantly revising their curriculum and methods based on outcomes, the latest in educational research, and community feedback. Just driving onto campus each morning feels good, because everything is done so well. The active and supportive parent community is wonderful. Lots of helpful parent Ed talks and resources (and plenty of nerdy, type A parents as you might imagine, that tend to knock whatever task they've volunteered for out of the park). Of course, each year is going to be different depending on the mix of parents, students, and faculty but the institutional structure of constant improvement and community involvement is one of the best I've seen.I also really appreciate the fact that my son is now middle-of-the-pack in terms of intellect and assertiveness, finding friends with similar interests and abilities. And I've been able to relax around the other parents who share similar experiences of parenting exceptional kids. Hope this is helpful; I know picking a school is a big decision and the cost is significant. All I can say it that we really love Open Window.

Our son has gone to Open Window from K - 8. Our experience, inclusive of his feedback, has been excellent. The mission of "children first, gifted second" has helped our son to become a great human being in addition to ultra-high standardized scores including the SSAT and ISEE tests. We would make the decision to send him here again without reservation. If you are a parent who demands "gifted first, children second" or a "tiger mom" type of parenting that is only focused on brutal rigor, home schooling may be a better option.
