You really have to take into account who your kid is and what your school offers and what your goals are. We live in good district (+1.8) and decided to send DS to a private school. He is in college now, and we feel like prep school tuition may end up being the best education dollars we’ll have spent. But YMMV. Here was why we made our decision the way we did…
Our public high school is huge and DS had managed to be invisible at his small public middle school. We felt like he’d remain invisible, and although the school offered a lot, he wouldn’t be able to access it. Such as sports… He was a good athlete, but with almost 4000 in the public high school, we were pretty sure that he wouldn’t make the team there. He did get to play at the private school and ended up with offers to play (D3) in college. Now, had he been a D1 football prospect, or had he needed to play on an elite club team to get recruited by a top flight school, public would have been better, but that wasn’t our situation. In addition, he was persuaded to try a new sport which again, he did well enough with to have (D3) opportunities to play. As you can imagine, one doesn’t try out for a team at the public school with no experience but at a smaller school, it’s encouraged. And he had to work his way up to varsity, but it was possible. Now, to OP’s point, did it help him get into a better school? He didn’t use sports to be recruited, (was contacted by the coaches after he’d been accepted RD), but I think that the colleges liked that he’d been engaged and successful. So not a hook, but a point in his favor maybe. And the bigger lesson to him was that by putting himself out there and participating, he’d make friends and feel more connected, a lesson which he’s taken with him to college. A good lesson for a reserved kid. Priceless, perhaps.
In addition, the way the scheduling was done at his prep school, he was able to continue to play an instrument. A friend at the public school (got a D1 lax scholarship) said that he wanted to do theater in HS but that it was impossible, both from a scheduling point of view as well as socially. At the prep school, most of the varsity athletes were also actors, artists, and/or musicians. Now who knows if this gets them into “better schools” (whatever that means!), but for a kid who wants more time to explore and develop different aspects of him/herself, being in the environment that allows that is key. DS was not keen to pursue music in college, but he has friends who are doing so. Did this help him get into college. Who knows? It showed that he was multi-faceted. But from my point of view, I’m glad he had this opportunity because later in life, he may want to do this again, and he’ll be able to.
Likewise, he could have happily sat in class and not participated much, and in classes with 30+ students, that would have been easy at the public school. He found, however, that he liked being in smaller classes with highly engaged, bright classmates and teachers who really encouraged him. In fact, he needed the encouragement. That experience determined what kind of colleges he liked and made him push himself more in high school. I suspect that it allowed his teachers to write meaningful recs about him. I feel like he went off to college better prepared and more engaged academically, but plenty of students could get there from any environment. While prep school made him a better student, his GPA was probably only in the middle of the class. But his school didn’t rank, so who knows whether it helped or hindered him in the college application process.
In the prep school environment, he took risks, tried new things, and developed confidence. He has friends who are much more diverse than the population served by our public school. I suspect that he interviewed well by the comments that came with the acceptance letters. As for the money, he ended up with a lot of merit aid that I don’t know that he’d have gotten coming out of a different environment. In fact, just a bit less than what we put into prep school. But then again, the kind of schools you’re targeting may not be the ones offering that money.
In a nutshell, I feel like DS got into a better college coming out of prep school because he was a better version of himself as a result of the environment he’d been in. And I feel like he is making more of the college experience as a result as well. But we didn’t go into it with the goal of having a “better” college outcome but of putting him in an place in which he would flourish which we were pretty sure he would NOT at the public school (based on our middle school experience).
So a few final thoughts…Don’t forget that you can use a fraction of private school tuition dollars for enrichment activities if your public high school is fundamentally a good place for your child but just missing a few bits. I have watched friends do this very successfully. High school should not be a protracted college application exercise but a place where your child can grow over the next four years. Thinking of it this way will make your decision easier. It could be that NOW is the best time to spend the money. Or you may want to keep your powder dry until college.
