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.

Open Quote I spent most of my life struggling in school but whenever one of my friends attending a different school are working on their homework, I automatically feel smart. I feel this way because I look over their shoulder and notice what they're working on and it's never even close to what I'm learning. Even though some of my friends are in the same grade as me, their education is not as great. I used to think it was a pain having such strict teachers but I honestly love it because I get the education that some students only dream of. I've come to notice that Radnor has a strong staff that not only cares about a student's academic performance, but makes it clear that they want you to succeed. It isn't everyday that some students can wake up to that. The facilities alone make me realize how blessed I am to be part of such an elite high school. I don't know who reads these reviews, but if this is a parent who is looking for a school for their kids, don't hesitate to keep this as an option. I have just started my senior year and since the first day I walked the halls of Radnor High, I've seen nothing but improvement when I thought it couldn't get any better. Close Quote

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.
