Summary

Unity Middle School serves 200 students in grades 5–8 in Mendon, Illinois. Its clearest strength is English language arts (ELA): in 2025–26, 71% of students were proficient, compared with 56% statewide and 60% in the district. That makes ELA the school’s standout result.

Unity’s ELA proficiency also topped nearby Central Junior High School (56%) and Quincy Junior High School (38%). Math is more mixed: Unity’s 40% was just above the state’s 40% and higher than Central’s 29% and Quincy’s 22%, but it was 6 percentage points below CUSD 4 (46%). Grade results show where the contrast lies: ELA proficiency reached 80% in grade 7 and 83% in grade 8, while grade 6 math was 29%, below the state’s 36% and Central’s 34%. The grade 8 math result is state-suppressed, so it cannot be compared.

Across the three supplied years, Unity’s ELA proficiency rose from 61% in 2023–24 to 71% in 2025–26; math increased from 32% to 40%, after reaching 42% in 2024–25. The school’s lead over the state narrowed in both subjects. SchoolDigger ranks Unity 372nd of 1,126 schools statewide, at the 67th percentile with three stars. Its student-teacher ratio was 12.6 in 2024–25, and 53% of students were free/reduced lunch eligible that year. SchoolDigger’s measure for “Low Socio Economic Status Students” rose from the 63rd percentile in 2023–24 to the 83rd in 2025–26, compared with the school’s overall 67th-percentile standing.
