St. Johns High

Summary:

St. Johns High is a public high school located in Johns Island, South Carolina, serving 387 students in grades 9-12 and is part of the Charleston 01 District, which is ranked 24th out of 75 districts in the state.

St. Johns High has a diverse student population, with 43.67% African American, 33.59% Hispanic, and 19.9% White students, which is notably different from some nearby schools. However, the school has consistently ranked in the bottom half of South Carolina high schools, with a 1-star rating from SchoolDigger for several years. Its performance on end-of-course exams is generally lower than the Charleston 01 district and state averages, particularly in subjects like Algebra 1, U.S. History, and English 2. While the school's African American and White students perform better than the overall school rankings, the Hispanic and English Language Learner students perform significantly worse.

St. Johns High has a 100% free and reduced-price lunch rate, indicating that the student population comes from low-income households, which is a key differentiating factor compared to some nearby schools. The school also has a relatively high per-student spending of $23,691 in the 2022-2023 school year, which is higher than the state average and some of the nearby schools, such as James Island Charter High and West Ashley High. However, the school's academic performance has declined over the past several years, suggesting that the resources are not yet translating into improved outcomes for students.

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.
