Summary

Old Post Elementary School is a public elementary school in Oswego, Illinois, serving students from kindergarten to 5th grade as part of the Cusd 308 district. The school has seen fluctuations in its statewide ranking over the years, but currently ranks 588th out of 2,056 Illinois elementary schools with a 4-star rating from SchoolDigger.

Old Post Elementary consistently outperforms the district and state in English Language Arts, Mathematics, and Science proficiency rates. In the 2024-2025 school year, the school's ELA proficiency rate was 61.6%, compared to 58.2% for Cusd 308 and 53.1% for Illinois. In Mathematics, the school's proficiency rate was 49.1%, compared to 43.6% for Cusd 308 and 38.5% for Illinois. However, the school's chronic absenteeism rate has been increasing, reaching 25.4% in the 2024-2025 school year, on par with nearby Prairie Point Elementary and Southbury Elementary.

While Old Post Elementary performs well overall, the school's Special Education and Disabled student subgroups have lower rankings compared to other Illinois elementary schools, suggesting opportunities for improvement in supporting these student populations. Despite this, the school's consistent high performance and strong rankings in other student subgroups, such as Hispanic and Low Socioeconomic Status, indicate a well-rounded and effective educational program.
