Apollo Elementary School consistently ranks in the bottom half of Illinois elementary schools, with below-average performance on state assessments in English Language Arts (ELA) and mathematics.

The school's performance is particularly low in mathematics, with only 14.5% of students proficient or better, compared to 12.2% for the district and 28.4% for the state. However, the school's performance on the Illinois Science Assessment (ISA) is better, with 43.9% of students proficient or better, compared to 60.6% for the district and 53.2% for the state.

Apollo Elementary School also struggles with high chronic absenteeism rates, ranging from 19.4% to 31.8% over the past 5 years, significantly higher than the state average of around 15%. Nearby schools, such as New Boston Elementary, Thomas Jefferson Elementary, and Ridgewood Elementary, generally perform better than Apollo Elementary on academic measures, with higher proficiency rates in ELA and mathematics. However, these nearby schools also have higher percentages of low-income students, which may contribute to their lower performance compared to the state averages. The highest-performing schools in the region appear to be Andalusia Elementary and the United Elementary School - West and United Elementary School - North in the Rockridge CUSD 300 district.

As you review the school rankings data, please be aware that some of the information from certain demographics is missing. The reason for this omission is that the data has been redacted from the source data itself due to low population samples in these specific demographic groups.

Redacting data from low population samples is a necessary step to ensure the reliability and accuracy of the results, as small sample sizes may not be representative of the broader population. Additionally, this measure helps protect the privacy of individuals belonging to these demographic groups.

About Students eligible for discounted/free lunch:

The National School Lunch Program (NSLP) provides low-cost or free meals to students in U.S. public and nonprofit private schools based on household income. Those with incomes below 130% of the poverty line receive free lunch, while those between 130% and 185% qualify for reduced-price lunch. The percentage of students receiving free or reduced-price lunch serves as a marker for poverty, as it reflects the socioeconomic status of families in a given school or district. A higher FRPL rate typically indicates a higher concentration of low-income families, suggesting that the school or district may face additional challenges in providing adequate resources and support for student success.

About Student-Teacher Ratio

Student/teacher ratio is calculated by dividing the total number of students by the total number of full-time equivalent teachers. Please note that a smaller student/teacher ratio does not necessarily translate to smaller class size. In some instances, schools hire teachers part time, and some teachers are hired for specialized instruction with very small class sizes. These and other factors contribute to the student/teacher ratio. Note: For private schools, Student/teacher ratio may not include Pre-Kindergarten.
