Summary

William M. Strong Elementary School is a PK–5 school in Plantsville, CT, serving 294 students as part of the Southington School District. The school is currently ranked 152nd out of 491 Connecticut elementary schools (69th percentile, 3 stars), a step back from recent years when it consistently earned 4 stars and ranked as high as 80th in the state in 2020–2021. Strong still scores above the Connecticut state average in most tested subjects, and its 12:1 student–teacher ratio and low free/reduced-price lunch rate of about 24% remain positive context for families.

The biggest concern for parents is third grade, where Strong's ELA proficiency (54.9%) and math proficiency (66.7%) were the lowest among all six Southington elementary schools in 2025–2026, well below district averages. Upper-grade results tell a different story: 4th grade math (78.6% proficient) and 5th grade ELA (72.3%) are strong, suggesting students gain ground as they move up. Chronic absenteeism also deserves monitoring — it rose from 5.3% to 8.7% in one year, though it remains well below the state average of 16.4%. Schools with the strongest rankings, such as Zaya A. Oshana Elementary School and Urbin T. Kelley School, have much lower absenteeism rates (3.4% and 4.1%).

Compared with nearby schools, Strong sits in the middle of the pack. It clearly outperforms Waterbury schools like Margaret M. Generali Elementary School and Rotella Interdistrict Magnet School, but trails most Wolcott and Cheshire schools, including Alcott School, Chapman School, and Frisbie School. Within the Southington district, Strong is currently fifth of six elementary schools, ahead of only Walter A. Derynoski Elementary School. Notably, William H. Hatton Elementary School serves a higher percentage of students from low-income families yet significantly outperforms Strong in third-grade ELA (82% vs. 54.9%) and math (90% vs. 66.7%). Still, Strong's consistency in 5th grade ELA — roughly 72% over the past four years — shows strong literacy instruction in the upper grades. The priority now should be diagnosing the third-grade slump and closely monitoring attendance trends.
