Summary
Tri-County Elementary is a PK–5 school of 265 students in Plainfield, Wisconsin, the elementary building of the Tri-County Area School District, where 64.5% of students qualify for free or reduced-price lunch — the highest poverty concentration among the nearby schools compared here. Tri-County Elementary currently ranks 735th of 1,039 Wisconsin elementary schools (29th percentile, 1 star), a modest rebound from the prior three years (21st–25th percentile) but far below 2017–18, when it reached the 59th percentile with 3 stars. The district itself ranks 381st of 432.
Reading sits close to the state line in grades 3 and 4, and 4th-grade social studies actually beats the state (70.6% proficient vs. 65.5%). Math is the clear weak point: averaged across grades 3–5, about 34% of students are proficient — the lowest of any comparison school, against a state figure near 52%. Fifth-grade reading has come in below the state in all four years tracked, and 3rd-grade math dropped from 50% to 25%. Nearby Wild Rose Elementary, similar in size with moderately high poverty, ranks at the 58th percentile with 60–82% proficiency, while Grant Elementary and Chain Exploration Center post much higher proficiency with far lower poverty rates. The closest peer, Almond-Bancroft Elementary, performs similarly weakly, and Tri-County generally edges it.
Attendance has been a relative strength, staying below both district and state rates for years, but chronic absenteeism more than doubled in 2024–25, from 7.5% to 15.2% — still better than the district's 19.4% but among the higher rates locally. Resources look adequate rather than advantaged: $15,020 per pupil and a 12.4 student–teacher ratio. Among student groups, low-income students, roughly two-thirds of enrollment, rank at the 65th percentile with 3 stars, while special education results fell sharply to the 3rd percentile. Bottom line: genuine but fragile momentum in reading and social studies, unresolved weakness in math, 5th-grade reading and special education, and attendance worth watching.
