Summary:
The 60439 zip code area is home to three elementary schools - Oakwood School, River Valley School, and Central School - all serving students from kindergarten through 6th grade and operated by the Lemont-Bromberek Central School District 113A.
Among the three schools, River Valley School and Central School stand out for their consistently high academic performance, outperforming both the district and state averages in English Language Arts (ELA) and Math proficiency. River Valley School ranked in the top 14% of Illinois elementary schools in 2020-2021, while Central School ranked in the top 19% in 2024-2025.
However, all three schools face a common challenge, with a chronic absenteeism rate of 25.4% for the 2024-2025 school year, which is higher than the state average. The district appears to allocate resources equitably, as evidenced by the similar spending per student and student-teacher ratios across the schools. This suggests that the strong academic performance of River Valley School and Central School is likely due to effective teaching and learning practices, rather than disparities in funding or staffing.
