Compared with nearby schools, Alden is the clear academic leader. It outperforms every tested nearby school in all three subjects and has a higher state rank percentile than all of them; the closest are Gov Edward Winslow (74th percentile) and South River (73rd). Notably, Alden achieves this without the smallest classes or highest spending: its student-teacher ratio is 11.8 and per-pupil spending $17,366, while Cold Spring ($20,616, ratio 9.7) and Hedge ($20,085, ratio 9.3) spend more and score lower. Watch items include the 2025–26 decline from the prior peak, with the largest drop in science (16.70 points), and recent softening in some student groups—though low-income and special education students still ranked well above average.
