Summary

Riverdale Middle School in Port Byron, Illinois, serves grades 6–8 and enrolls 254 students. Its most important strength is strong performance in both English Language Arts (ELA) and math: in 2025–26, proficiency was 75% in ELA and 52% in math, both well above state results.

Compared with nearby schools serving the same grades, Riverdale’s results stand out: its ELA proficiency was 19 points above their average of 57%, and math was 23 points above their average of 29%. It ranked second among nearby schools in ELA and third in math. The school still trailed Riverdale CUSD 100 in both subjects: district proficiency was 76% in ELA and 56% in math. Riverdale was above the state in each subject, whose results were 56% in ELA and 40% in math. The main concern within the school is the drop in math proficiency by grade: it was 65% in sixth grade, 54% in seventh and 36% in eighth, just above the state’s 35% for eighth grade. Chronic absenteeism was 14%—below the state’s 24%, but slightly above the district’s 13%.

Scores have risen since 2023–24: ELA increased from 60% to 75%, and math from 34% to 52%. SchoolDigger places Riverdale at the 74th statewide percentile with 4 stars in 2025–26, the highest percentile among the nearby schools, narrowly ahead of Erie Middle School at the 73rd percentile. Riverdale’s percentile was 80 the previous year. Context for families: in 2024–25, 16% of students were free/reduced lunch eligible, the lowest rate among nearby schools reporting the same measure, and the student-teacher ratio was 14.1. One notable SchoolDigger subgroup result is its statewide measure for how well it serves Special Education Students: the percentile was 16 in 2024–25, down from 49 in 2022–23, compared with an overall percentile of 80 in 2024–25.
