Best Public Schools in Zip Code 06351

ZIP code 06351, covering Griswold, Jewett City, and Lisbon, Connecticut, is served by five schools across the Griswold School District and the Lisbon School District, offering programs from pre-kindergarten through 12th grade to about 2,222 students. The standout school in the area is Lisbon Central School, which serves grades PK–8 and posts the lowest chronic absenteeism rate (10.8%) and lowest economic disadvantage rate (36.56%) in the ZIP code. It also leads in test performance, with 3rd grade ELA and math proficiency around 63.6% and 8th grade math at 58.8%, all well above state averages. Griswold Middle School is the strongest traditional public school in Griswold, with a notable 66% proficiency rate in 8th grade ELA, though its lower grades lag behind state averages in both math and reading.

Chronic absenteeism is the area's most significant warning sign, rising sharply at the high school level: Griswold High School has a 26.7% chronic absenteeism rate despite a solid 91.8% graduation rate. Griswold Elementary School shows a concerning drop-off after 3rd grade, with math proficiency falling from 50.9% in 3rd grade to 36.8% in 4th grade, indicating a possible transition problem between primary and upper elementary instruction. Meanwhile, Griswold Soule Street Academy is a clear outlier: with only 19 students, a 96.2% chronic absenteeism rate, and per-student spending of $303,964, it operates as a specialized alternative setting that should not be compared to traditional schools.

Overall, the area faces significant challenges but has clear strengths. Four of the five schools have over half their students eligible for free or reduced-price lunch, and district-wide absenteeism in Griswold (19.1%) trails the state average of 16.4%. However, strong 8th grade results at both Griswold Middle School and Lisbon Central School prove that students here can achieve at or above state levels. The key priorities for improvement are reducing high school absenteeism, stabilizing elementary math performance, and maintaining the upper-middle-grade gains that show real promise for this community.
