Virtual schools are left out, because a school with no building is not comparable to one with a campus. Public counts come from the federal Common Core of Data, which every public district reports to. Private counts come from the federal Private School Universe Survey.","Enrollment for public schools is the number of students in grades 9 through 12, so a school that also teaches middle school grades is not inflated by them. A school that reports no enrollment figure is counted in the state total but cannot be ranked, which is why the number of schools with an enrollment figure is smaller than the public count."]},{"h2":"Private high schools in Pennsylvania","paragraphs":["The private table below shows the largest private high schools whose lowest grade is 9. The survey is voluntary, so treat these as the largest among the schools that answered, not a complete ranking. A private school that declines the survey does not appear at all.","Private enrollment is a total, not a grades 9 through 12 count, because the survey does not break it out the same way. Limiting the list to schools that start at grade 9 keeps the figures comparable to each other."]},{"h2":"What a family should do with this","paragraphs":["Size is a starting point, not a verdict. A large school usually offers more courses, more sports and more clubs, and a small school usually gives a student more contact with the adults who write recommendation letters. Both shapes send students to good colleges.","The more useful question is where a school's own graduates actually go. Our page for each Pennsylvania high school carries that school's figures and, where the school publishes one, its own numbered list of the colleges its graduates chose.
