Summary:
Zip code 06239 contains exactly one elementary school: Killingly Memorial School in Danielson, Connecticut. The school serves grades 2 through 4 and has an enrollment of 485 students within the Killingly School District. Since only one school is present in this zip code, the following insights provide a detailed profile of this single school rather than a comparison of multiple schools.
The most striking finding is the school's low chronic absenteeism rate. At 12.8 percent, it is far below both the district's 23.0 percent and the state average of 16.4 percent, despite a majority of students qualifying for free or reduced-price lunch. Academically, math stands out as a strength. In the 2025–2026 school year, 3rd grade math proficiency reached 51.3 percent and 4th grade reached 51.1 percent, both within about one point of the state average. English Language Arts is the main challenge, with 3rd grade proficiency at 41.3 percent versus 47.3 percent statewide, though this reflected a substantial one-year gain of 7.7 percentage points.
Killingly Memorial School's statewide rank has improved for three consecutive years, rising from the 39th percentile in 2023–2024 to the 43rd percentile in 2025–2026, while the school maintains a 2-star rating compared to the district's 1-star rating. A favorable student–teacher ratio of 12.2 may support more individualized instruction. Because the school spans only grades 2 through 4, early literacy and grade 5 transition data are not visible in this profile. Overall, this is a mid-range elementary school with strong attendance, near-state-average math performance, and a positive upward trajectory, with ELA as the key area for continued improvement.
