In the most recent 2025-26 school year, the school's strongest academic showing was in 8th grade science, where 52.1% of students scored proficient on the NGSS exam, slightly exceeding both the district rate of 51.3% and the state rate of 50.9%. The school also posted notable year-over-year math gains in 6th grade, rising from 14.9% to 30.3% proficiency, and in 8th grade, jumping from 13.5% to 30.3%. English Language Arts performance is moderate, averaging 43.9% proficiency compared to the state's 52.0%, with 6th and 8th grades closest to the state average. However, math remains a significant challenge, with average proficiency of just 26.4% versus 44.1% statewide, and no grade level reaching even 31% proficiency.

There are a few notable concerns, however. Chronic absenteeism affects 24.3% of students, well above the state rate of 16.4%, and more than half of the student body (52.3%) qualifies for free or reduced lunch. The 7th grade experienced a sharp decline this year, with ELA proficiency dropping from 53.4% to 34.9% and math from 33.1% to 23.1%, indicating possible cohort-specific challenges. On a positive note, the school maintains a favorable student-teacher ratio of 12.3, and per-student spending was $16,611 in 2018-19. Overall, Killingly Intermediate School is a steadily mid-performing school with bright spots in science and recent math improvement, but closing the gap with the state will require targeted efforts in math instruction, attendance, and support for the 7th grade.
