Summary:
Thomaston, Connecticut is a small town served by a three-school public district, the Thomaston School District, which includes an elementary school (Black Rock School, PK–3), a middle school (Thomaston Center School, 4–6), and a high school (Thomaston High School, 7–12).
For parents, the standout is Thomaston High School, which earned a perfect 100% graduation rate and posted strong science and middle-grades math scores—8th grade math was 61% proficient compared with 42% statewide, and 8th grade science hit 70% versus 50% statewide. It also improved from a 2-star to a 4-star rating over time. However, the same school shows a troubling 11th grade SAT math proficiency of just 17.4% versus 31.3% statewide, and its chronic absenteeism rate of 17.2% is higher than the district and state averages. In contrast, Thomaston Center School has excellent attendance—only 7.5% chronically absent—but math is a major issue: 5th grade math proficiency was just 11.5% versus 45.8% statewide. Black Rock School also has solid attendance (10.2%) but limited academic data; its only available score, 3rd grade ELA, was 38.3% versus 46.9% statewide.
The district shows a striking math paradox: students appear to improve dramatically between 6th and 7th grade, then fall off sharply by 11th grade. Science is a clear strength across all grade levels. Attendance declines as students get older, and the middle school has the highest poverty rate (46.4% free/reduced lunch) alongside the lowest math scores, though poverty alone does not explain the pattern. The high school spends the most per student ($19,152) and has the lowest student-teacher ratio, yet its older students struggle with college-readiness in math. Overall, Thomaston offers a strong high school experience with notable academic wins, but families should pay close attention to math proficiency in the elementary and middle grades and to attendance trends in high school.
