Summary:

The city of Waterloo, Illinois is home to a single high school, Waterloo High School, which serves grades 9-12 and is part of the Waterloo CUSD 5 district. This high-performing institution has consistently ranked in the top 25% of Illinois high schools over the past 3 school years, with a ranking as high as 76th out of 697 schools in 2023-2024. Waterloo High School maintains a 4-star rating from SchoolDigger, indicating it is performing well above average.

The school's academic excellence is evident in its strong proficiency rates on standardized tests like the ACT and SAT, which exceed state averages across multiple subject areas. Waterloo High School also boasts an impressive 89% graduation rate in 2024-2025, significantly higher than the state average. Additionally, the school's dropout rate of 2.4% in 2024-2025 is lower than the state average, and its student-teacher ratio of 17.3 to 1 in 2023-2024 is a favorable ratio.

While Waterloo High School's performance is strong overall, the school's slightly higher chronic absenteeism rate of 25.4% in 2024-2025 suggests there may be opportunities to further engage students and improve attendance. However, the school's relatively low poverty rate, with 20.02% of students qualifying for free or reduced-price lunch in 2023-2024, indicates a supportive environment for students to thrive academically.
