Santa Susana High

Summary:

Santa Susana High is a public high school located in Simi Valley, California, serving grades 9-12 with a total enrollment of 1,073 students. This school is part of the Simi Valley Unified School District, which is ranked 667 out of 1,568 districts in California and has a 3-star rating from SchoolDigger.

Santa Susana High consistently ranks among the top high schools in California, with a statewide ranking between 71 and 226 over the past 10 years. The school has maintained a 5-star rating from SchoolDigger for most of the past decade, indicating excellent academic performance. In the 2023-2024 school year, Santa Susana High ranked 212 out of 2,323 California high schools and received a 5-star rating. The school's students perform significantly better than the district and state averages in Smarter Balanced Assessments for English Language Arts/Literacy and Mathematics, as well as in the California Science Test (CAST). Additionally, Santa Susana High has consistently high four-year graduation rates, ranging from 94.7% to 99.6% over the past five years, and very low dropout rates, ranging from 0.0% to 4.8% during the same period.

While Santa Susana High outperforms the other high schools in the Simi Valley Unified School District, including Royal High and Simi Valley High, in academic metrics, its performance is not as strong as that of high-performing schools in the neighboring Oak Park Unified School District, such as Oak Park High and The High School at Moorpark College. Additionally, the school's relatively low percentage of students from low-socioeconomic backgrounds, with around 30% of students qualifying for free or reduced-price lunch, suggests that the school's strong academic performance may be influenced by the socioeconomic status of its student population. The increase in chronic absenteeism rates at Santa Susana High, rising from 6.8% in 2017-2018 to 15.3% in 2021-2022, is a concerning trend that the school should investigate and 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.

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.
