Summary:
The Lisbon School District in Connecticut has one elementary school, Lisbon Central School, which serves grades PK–8 with 413 students and a student-teacher ratio of 13.9. This single school represents the entire district at the elementary level, and its performance tells a story of strong early learning, a mid-elementary dip, and a remarkable rebound in middle school math.
In 2025–2026, the school ranked in the 45th percentile statewide (271 out of 491 schools), recovering from a dip to the 34th percentile the previous year. Chronic absenteeism stands at a healthy 10.8%, well below the state rate of 16.4%, even though about 36.6% of students qualify for free or reduced-price lunch. Spending per student is $18,476, and class sizes are modest. The strongest academic results come in the early grades: 3rd graders exceed the state by 16.3 points in English Language Arts and by 11.4 points in math. However, 5th grade is a clear weak spot, with math proficiency at just 23.7% (22.1 points below the state) and ELA at 35.9% (17.6 points below). This suggests a difficult transition or curriculum challenge in upper elementary.
Encouragingly, math performance recovers sharply in middle school: 7th grade math is 58.3% proficient (+14.2 vs. state), and 8th grade math hit 58.8% in 2024–2025 (+18.0). From 2024–2025 to 2025–2026, 4th grade math improved by 17.4 points, nearly reaching the state average. Attendance is a clear strength, and the school maintains a consistent 2-star rating. For parents, the key takeaway is that Lisbon Central School provides a strong foundation and excellent middle school math outcomes, but families should be aware of the 5th grade slump and look for supports during that transition year.
