<p>My family’s experience bears out what leonine says, too. My children moved from a prestigious, academically oriented private school (class = 95, avg SATs = 1300) to a large public magnet (class = 550, avg SATs = 1100). The “top” 50 kids at each school (whatever that means) were pretty equivalent in ability (but that was more than half the private school class and less than 10% of the public school class). The public school group was much more diverse in every way, much more focused, much more competitive, and also far more oriented towards math and science.</p>
<p>In terms of college admissions, the best 20-30 students at each school had pretty much equivalent results. Below that level, the private school has better results in terms of prestige. But it’s a little hard to compare, because (a) about half the private school kids go to LACs, and only 6-7 kids per year from the public school even apply to LACs, (b) the public school kids are much more likely to choose a less prestigious school because it offers more financial aid, and also much more likely to want to go to college relatively close to home, and (c) the public school produces many more recruited athletes. If you looked at the kid ranked #50 in each class (the private school doesn’t rank, of course), at the public school s/he’s going to Penn State, at the private school s/he’s going to Oberlin or Middlebury. I am pretty convinced that if my kids had stayed at the private school, they would probably be attending exactly the same college.</p>
<p>The private school is warm, intimate, and does an especially good job with smart kids who don’t know what they want, or who may be a little rebellious. The public school is somewhat sink-or-swim, great for focused self-starters, but possible to get lost in. It’s not necessarily a great place for a kid who’s going to stumble more than once or twice (although, for all its bureaucracy, it is surprisingly and impressively personal and caring). Objectively, the private school is almost certainly the better school overall, but the public school is better in some areas, notably science (lots of kids doing research, lots of support for that). And the cultural/ethnic/class/political diversity of the public school is really exciting.</p>
<p>Anyway, my point is that this public school, while not perfect, is easily comparable to a great private school. But that’s because it really has a critical mass of strong, ambitious students, and a learning environment. And because of that, it’s not at all easier to stand out there than at the private school. More troubled public schools would be a different story altogether. And paradoxically, the private school, although known for its academic stars, really has the most value for the kids who aren’t academic stars. No one leaves the private school without a very good education and a very good college placement. You can’t necessarily say that of the public school.</p>
