South Lyon High School

Summary:

South Lyon High School is a public high school serving 1,293 students in grades 9-12 in South Lyon, Michigan, which is part of the South Lyon Community Schools district. The school consistently ranks among the top high schools in Michigan, with a statewide ranking between 28 and 103 over the past 10 years and a 4- or 5-star rating from SchoolDigger.

South Lyon High School stands out for its strong academic performance, with students consistently outperforming state and district averages on M-Step and SAT assessments, particularly in Evidence-Based Reading and Writing. The school also maintains a high four-year graduation rate, ranging from 90.0% to 94.7% over the past 5 years, which is higher than the state average. However, the school's student population is significantly less diverse than the surrounding schools, with a much higher percentage of white students at 87.94%. This lack of diversity may be an area for the district to explore in terms of promoting inclusion.

Compared to nearby schools like Charyl Stockwell Academy High School, Northville High School, and Walled Lake Western High School, South Lyon High School stands out for its consistently high academic performance and graduation rates. However, the school's increasing chronic absenteeism rate, from 11.4% in 2018-2019 to 17.4% in 2022-2023, is an area of concern that the South Lyon Community Schools district may need to address.

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 Things often break or are worn, building in poor condition, only recently upgraded to 'new' technology, most of the money does not go to fixing the school, but rather goes into the new "East" high school, leaving SLHS in a poorly state. Not many class or lunch options, do not have many options for students with working families.
Staff unattentive to students needs: Many students are not given AP summer homework and start the year terribly behind other students (I was included in this). They do not have enough college prep programs offered. 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.
