Summary:
Tri City CUSD 1 has one middle school, Tri-City Junior High School, serving grades 6–8 and enrolling 137 students in 2024–2025. There are no other middle schools in this dataset to compare, so the most useful picture is how the school’s results compare with Illinois and how they differ across grades. The clearest headline is that in 2025–2026 the school was above the state in every reported subject, with its largest overall advantages in eighth-grade science and all-grades English language arts (ELA).
Tri-City Junior High School stands out most in ELA and science: all-grades ELA proficiency was 72%, versus 56% statewide, a 16-percentage-point lead; eighth-grade science was 73%, versus 52%, a 21-point lead. Math was a relative strength too, but the all-grades margin was smaller: 44% versus 40%, or 5 points higher. Within the school, eighth grade had the strongest state-relative results, especially in math (52% versus 35%, an 18-point lead). Seventh grade had the narrowest leads: 6 points in ELA and 2 points in math. These differences show why the all-grades figures alone do not capture every grade’s profile.
Results improved from 2024–2025 to 2025–2026, most sharply in ELA and eighth-grade science: ELA rose from 60% to 72%, math from 42% to 44%, and science from 54% to 73%. The school’s lead over the state widened in all three comparisons, by 9 points in ELA, 1 point in math, and 13 points in science. SchoolDigger places the district at four stars and ranks it 198th of 738 Illinois districts; the school’s SchoolDigger percentile rose from the 66th in 2023–2024 to the 70th in 2025–2026. Other context includes an 11.3:1 student–teacher ratio and 49% of students free/reduced lunch eligible in 2024–2025. Chronic absenteeism was 13% in 2025–2026, below the district’s 17% and the state’s 24%. With only one school listed, these figures describe its context but do not allow comparisons among area schools.
