SchoolDigger’s rank history shows different trajectories, not one area-wide direction: Longfellow Elementary School rose from the 4th to the 39th percentile between 2023–24 and 2025–26, while Montessori moved from the 96th to the 89th; Franklin stayed at the 96th percentile. Those rankings do not always match current results: Longfellow’s all-grades scores are 25% in ELA and 26% in math, both below state results. Science offers another comparison: average 5th-grade proficiency is 39%, versus 34% statewide, and Montessori reports the area’s highest result at 79%. Enrollment and student–teacher ratios alone do not explain the differences: Franklin has 518 students and a 18.7 ratio, while Holmes has 536 students and a 15.7 ratio, yet their results are sharply different.
