Summary

Apollo Elementary School is a public elementary school located in Aledo, Illinois, serving 345 students in grades K-5. The school is part of the Mercer County School District 404, which is ranked 549 out of 811 school districts in Illinois and has a 2-star rating from SchoolDigger.

Academically, Apollo Elementary School has shown mixed performance compared to state and district averages. In the 2024-2025 school year, the school had 58.1% of students proficient or better in English Language Arts, higher than the district (46.4%) but lower than the state (53.1%) average. In mathematics, the school had 33.2% proficiency, higher than the district (25%) but lower than the state (38.5%) average. However, the school performed better in science, with 51.5% proficiency, higher than both the district (52.2%) and state (40.6%) averages. When compared to nearby schools, Apollo Elementary generally performs better than the Mercer County School District 404 average but lags behind some higher-performing schools in the region, such as Andalusia Elementary School and United Elementary School - North.

The school has also faced challenges, such as relatively high chronic absenteeism rates ranging from 18.3% to 28.3% over the past few years, which is higher than the state average. Additionally, the school's spending per student has increased from $11,939 in 2020-2021 to $15,621 in 2023-2024, which is higher than the state average, but this increased funding has not yet translated to significantly improved academic outcomes. The school should continue to explore ways to optimize the use of its resources and address the root causes of chronic absenteeism to drive better student achievement.
