Summary:
Zip code 20676, covering the Port Republic area of Maryland, is home to a single school: Mutual Elementary, a public school serving grades Pre-K through 5th with 374 students.
As the only school in the zip code, Mutual Elementary stands out on its own merits as a high-performing institution within the top-ranked Calvert County Public Schools district. In the 2025-2026 school year, the school ranked 149th out of 864 Maryland elementary schools (83rd percentile) and earned a 4-star rating, showing a strong upward trend from a 226th-place ranking just two years prior. Academically, Mutual Elementary significantly outperforms both district and state averages: 71.9% of students are proficient in English Language Arts (compared to 66.6% district and 51.7% state), and 50.5% are proficient in math (compared to 37.9% district and 27.1% state). The school also boasts a low student-teacher ratio of 14.3:1 and per-student spending of $21,572, indicating strong resource allocation.
One notable finding is a sharp drop in 4th-grade math proficiency, which falls to 40.7% from 64.1% in 3rd grade—the only grade where the school performs below the district average. However, the overall trajectory is positive, with consistent year-over-year improvements in both ELA and math scores. Chronic absenteeism sits at 15.8%, slightly better than the district average, and 32.35% of students qualify for free or reduced lunch, reflecting moderate economic diversity. For parents, Mutual Elementary represents a well-funded, academically excellent school with a clear upward momentum, though the 4th-grade math dip may warrant attention.
