One is a fast-growing suburb that builds one very large high school instead of three. Conroe, Allen, Prosper and Carmel are in that group. The other is a city magnet or exam school that draws from the whole district, which is how Brooklyn Technical High School, Lane Technical High School and Francis Lewis High School got here.","Size by itself is not good or bad news. A very large school can run a long AP list, a dozen sports and several languages that a small school cannot. The same school can also be a place where a quiet ninth grader is never noticed."]},{"h2":"What the enrollment number covers","paragraphs":["The figure is the count of students in grades 9-12 at that one campus, as the district filed it with the federal government for 2023-24. It is not the district total, and it does not include a middle school that shares the name or the site. A school's own site may show a newer number for this year, and the gap is usually small."]},{"h2":"What a family should do with this","paragraphs":["If your student is headed to a school on this list, the question is not size but structure. Find out how ninth graders are grouped, whether there are smaller academies or houses inside the building, and how many students each counselor carries. That last number sits on the school's page on Reach.","Then read the course list rather than the brochure.
