<p>I go to the highest ranked open enrollment school on this list. Our STEM program is significantly worse than those at schools like TJ or High Tech, but we are ranked very close to those schools based on AP classes and exams. There are many problems with this.</p>
<p>First, the index doesn’t account for how many AP STEM courses are offered. If a school has an extremely large enrollment and success in AP Statistics, for example, but only offers that AP math course, then it may be ranked above a school that has many AP math offerings but not as many people in them. Our school didn’t have AP Physics C until this year, yet countless other schools offered this course long before us, while we are ranked the 10th best STEM high school. We have zero computer science courses, and the computer science club that my friends and I are starting is having trouble finding an adviser for a computer competition, which should be rare in a school renown for its STEM programs.</p>
<p>Another problem with ranking using APs at the top is that these schools have nontrivial post-AP STEM programs (i.e. multivariable calculus, linear algebra, differential equations), but there is no comparison between those. I am sure, for example, that Stuyvesant’s STEM programs are much better than ours, yet we are ranked higher just because of the sheer number of students that take AP STEM courses, many due to parental pressure. Our post-AP offerings are limited to multivariable calculus and linear algebra (which we only got this year), which are, so far, very computational rather than mathematically rigorous. In contrast, I suspect the same class at TJ or another top magnet school has more theory and is more rigorous. Also, top magnet schools often have college-level/advanced electives such as real analysis, organic chemistry, or computational biology, so they also have more extensive post-AP offerings than us.</p>
<p>Nor does the index account for the rigor of the AP STEM courses at high-performing schools, due to the thresholds for achieving a passing grade on an AP exam. For a high-performing student, it is fairly easy to pass any AP exam, given enough studying. The difference between a 3 and a 5 is not terribly large, either, when you look at how AP tests are graded. When you have students that easily get 5s on the AP Chemistry or the AP Calculus BC exams, then you need to look at factors beyond AP tests (i.e. olympiads and other STEM competitions) to evaluate how schools compare to each other. For example, I felt that the AP Calculus BC and AP Physics B exams weren’t very difficult at all to get a 5 on, and I am a top student in my school, but at a school like TJ, I would probably be merely average (though the different environments may affect how one performs).</p>
<p>So for the top 25 or so (maybe top 50), I wouldn’t trust the order of the rankings here. Many of the higher-ranked schools perform indistinguishably on AP exams, while they can vary greatly on more advanced coursework and preparation for STEM competitions. A more appropriate name for these rankings would be “Schools with the Most STEM AP Course Takers”, though that still wouldn’t be entirely accurate.</p>
