Lisbon School District

The Lisbon School District in Connecticut is a single-school district that serves students from Pre-K through 8th grade, with just one campus, Lisbon Central School, enrolling 413 students. Because the school and district are the same entity, Lisbon Central School truly represents the entire district's performance, and there are no separate middle or high schools to compare against.

Lisbon Central School has some notable strengths worth highlighting for parents. Third graders are performing well above state averages in both English Language Arts and Math, with 63.6% proficiency in each, compared to 47.3% and 52.2% statewide, respectively. Middle-school math is also a bright spot, with 7th grade math proficiency at 58.3% versus 44.1% statewide, and 8th grade math hit 58.8% in the 2024-2025 school year. The school also enjoys favorable conditions: a low chronic absenteeism rate of 10.8%, a strong student-teacher ratio of 13.9, and per-pupil spending of $18,476. The school has a 36.56% free/reduced lunch eligibility rate. Despite these advantages, the district ranks 106th out of 153 Connecticut districts, placing it in the 31st percentile.

The biggest concern is a significant drop in upper-elementary performance. Fifth grade math proficiency is just 23.7%, compared to 45.8% statewide — a roughly 22-point gap. Fifth and sixth grade ELA proficiency also lag at 35.9% and 35.2%, respectively, versus state averages around 53.5% and 51.2%. This creates a "U-shaped" pattern in math scores: strong in 3rd grade, dipping sharply in 5th, and recovering in 7th. On a positive note, year-over-year gains include 4th grade math jumping from 34.1% to 51.5%, and 7th grade math improving from 46.5% to 58.3%. However, with favorable conditions like low absenteeism and small class sizes, the inconsistent results suggest instructional or curricular challenges may be at play rather than resource or attendance issues.
