This high-performing school consistently ranks among the top 100 high schools in Illinois, with strong academic metrics, high graduation rates, and well-rounded performance across student subgroups.

While O Fallon High School's overall performance is impressive, the school may want to focus on addressing areas of concern, such as chronic absenteeism, which has fluctuated in recent years, and supporting specific student populations, such as special education students and those from low socioeconomic backgrounds, where the school's rankings are lower compared to other subgroups. The school's increased spending per student, from $10,594 in 2019-2020 to $13,269 in 2022-2023, may have contributed to its strong academic performance and could be an area to continue investing in to ensure continued success and improvement.

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.
