Cider Mill ranked 68th in Connecticut in 2025-2026 (86th percentile), a slight slip from 46th the prior year.

Both schools are exceptionally stable with low poverty levels, reflected in chronic absenteeism around 4% versus the 16.4% state average. Per-student spending is nearly identical ($20,789 at Miller-Driscoll vs. $20,884 at Cider Mill), and student-to-teacher ratios are low (13:1 and 12:1).
