<p>When we were in NYC, we faced a situation just the opposite of the one Allmusic posited.</p>
<p>We had kids who were academically far above grade level, and the local schools would not cater to such children.</p>
<p>For us at that time, the primary issue was tracking. The public schools didn't track. When students of mixed academic abilties are all lumped together the interests of almost none of them are optimally served. My kids were bored in the public schools, and they weren't learning anything.</p>
<p>For the academically able, private schools solved this issue in two ways. First of all it only admitted academically apt students to start with. Second of all it's smaller class sizes and low student/teacher ratios allowed them to break classes into small groups which were more homogeneous in capabilties. Consequently each group our kids were in could proceed at the pace most closely matched to the needs of our particular kid. The work they did was way beyond grade level. They were no longer bored. They were challenged.</p>
<p>In high school, in many cases the situation is not as drastic because many high schools still do track to an extent. At the least they do this by establishing standards for enrolling in AP classes. Still the degree of tracking that my kids experienced was not the same as at a private school. They went to an allegedly "good" public school, and basically the top 10% there was equivalent to the top 40% at the local private school. This was evident when the college lists came out; it was an affluent area so money wasn't the sole issue. This degree of differing academic capabilities has to, and did I believe, affect the level of the their classes on a daily basis.</p>
<p>The smaller classes in the private school allowed for teachers there to assign more assignments like papers that they had to grade. This helped kids develop their writing skills more.</p>
<p>THe smaller school made it more likely that our kids could have significant participation in various clubs and sports teams. They were competing for slots with 100 kids, not 500+ kids.</p>
<p>So I still see advantages in high school, in at least some cases.</p>
<p>I may be naive, but I don't think most parents select private schools for their own networking. I think they might do it mostly for the reasons I described above. But also if there's a networking angle then it's for the kids' networking. You are putting them in an environment where there are a higher percentage of kids who share intellect, family circumstances, and other interests so it seems reasonable that friendships with like-minded individuals might be more likely in this envirnonment.</p>
<p>We didn't make it there long enough to face a choice vs. Stuyvesant. but the concern would be whether the disparate kids there really socialize, or break down into cliques along cultural and ethnic lines. I've heard it's more the latter. That, plus the large class sizes, and other issues cited above.</p>
