San Lorenzo High

Summary:

San Lorenzo High is a public high school serving 1,186 students in grades 9-12 in San Lorenzo, California. The school is part of the San Lorenzo Unified School District, which is ranked 1,186 out of 1,568 districts in the state and has a rating of 1 out of 5 stars from SchoolDigger.

San Lorenzo High has consistently ranked in the bottom half of California high schools over the past decade, with its statewide ranking ranging from 1,042 out of 2,354 schools in 2011-2012 to 1,767 out of 2,323 schools in the current 2023-2024 school year. The school's academic performance, as measured by standardized test scores, is significantly below the state and district averages, with only 21.46% of 11th-grade students proficient or better in English Language Arts/Literacy and just 7.5% proficient in mathematics. The school's graduation rate, while still above the state average, is lower than the San Lorenzo Unified district average, and its dropout rate is higher than both the state and district averages.

Interestingly, nearby schools like Arroyo High and KIPP King Collegiate High significantly outperform San Lorenzo High across various metrics, highlighting the need for targeted interventions and support to improve academic outcomes at San Lorenzo High. The school's struggles are particularly pronounced for certain student subgroups, such as Hispanic and low-socioeconomic status students, suggesting the need to address the unique needs of its diverse student population. Addressing the high and increasing rates of chronic absenteeism, reaching nearly 50% in 2020-2021, should also be a priority for the school and district.

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.
