Summary:
Plymouth School District is a small Connecticut district serving 1,233 students across four schools: Plymouth Center School (PK-2), Harry S. Fisher Elementary School (3-5), Eli Terry Junior Middle School (6-8), and Terryville High School (9-12). The district ranks 131 out of 153 Connecticut districts—the 14th percentile—with a 1-star rating, and free/reduced lunch eligibility ranges from 46.5% to 54.3% across schools.
Eli Terry Junior Middle School is the district's current academic standout, particularly in science: 8th-grade science proficiency hit 62.0% in 2024-25 versus 50.3% statewide, and 48.2% in 2025-26 versus 50.9% statewide. Harry S. Fisher Elementary School has the best attendance (13.8% chronic absenteeism, well below the district's 17.0% and state's 16.4%) and shows early-elementary math strength—4th-grade math reached 51.5% in 2025-26, nearly matching the state's 52.1%—but 5th-grade results lag significantly, with math at 24.7% in 2024-25 versus 44.9% statewide. Terryville High School is the most concerning school: chronic absenteeism is 21.3%, 11th-grade math proficiency collapsed from 28.0% to 15.7% in one year, and its rank fell from the 56th to the 28th percentile. Plymouth Center School serves only PK-2 and has no recent test data, but was historically the district's strongest school (79th percentile with 4 stars in 2018-19).
Key takeaways: Terryville High School still posts a 93.2% graduation rate, above the state's 91.2%, despite low test scores and high absenteeism. The district spends generously—Harry S. Fisher Elementary School at $18,214 per student and Eli Terry Junior Middle School at $15,075—yet achievement sits in the bottom 14% statewide. For parents, this is a district with genuine pockets of strength—middle school science, early-elementary math, and high school graduation—but also persistent academic gaps, particularly at the high school level and in upper elementary grades.
