Slidell High School

Summary:

Slidell High School is a public high school in Slidell, Louisiana, serving 1,883 students in grades 9-12. The school is part of the St. Tammany Parish school district, which is ranked 21 out of 122 districts in Louisiana and has a 4-star rating.

While Slidell High School has a more diverse student population compared to nearby schools, with higher percentages of African American (35.79%) and Hispanic (9.61%) students, its academic performance lags behind the district and state averages. For example, in the 2023-2024 school year, Slidell High's proficiency rates were lower than the St. Tammany Parish and Louisiana state averages in Algebra I (56% vs. 71% and 62%), Geometry (55% vs. 64% and 58%), and U.S. History (52% vs. 69% and 57%). Additionally, Slidell High has a higher student-teacher ratio (20.1) compared to Fontainebleau High School (19.5) and Lakeshore High School (17.7), and a higher percentage of students receiving free or reduced-price lunch (52.2%) than the nearby schools.

Interestingly, Slidell High School's statewide ranking has been declining over the years, from a high of 43 out of 309 Louisiana high schools in 2013-2014 to 187 out of 333 in 2023-2024, with a corresponding drop in its SchoolDigger star rating from 4 to 2. The school's performance also varies significantly across different student subgroups, with the school ranking in the top 50% for African American students but in the bottom 25% for Hispanic, White, and low-socioeconomic status students. Compared to nearby schools like Fontainebleau High and Lakeshore High, which consistently outperform Slidell High, the data suggests that Slidell High faces significant challenges in providing equitable educational opportunities for all its 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.
