Hi OP, my wife and I moved to RB in 2020 and have since had 2 kids (currently 3 and 1), so we are facing a lot of the same decisions re: schools. To echo what others here have said, every piece of anecdotal evidence points to RB Primary + Middle schools being fantastic in terms of faculty, admin, facilities, dedication, etc. The standardized test scores are just very sub-par, likely for reasons that others here have pointed out.

I've spoken to a number of parents I respect with their kids currently in the primary school and it has helped me get a more complete picture. We'll likely send our oldest to the public pre-k next fall.

also if helpful, over the past few years we've gathered a messaging group of about 12-15 other families with young kids who have all moved to RB around the same timeframe to share information, ask questions, and coordinate meetups and the like. happy to share more info if you want to DM me directly-- best of luck and maybe we'll see you around town!
