Redwood Continuation High

Summary:

Redwood Continuation High is a public high school located in Castro Valley, California, serving grades 9-12 with a total enrollment of 122 students. As part of the Castro Valley Unified School District, which is ranked 214 out of 1,568 districts in California, Redwood Continuation High faces significant challenges in academic performance, graduation rates, and student engagement compared to its nearby counterparts.

Redwood Continuation High consistently ranks in the bottom 20% of California high schools, with a 1-star rating from SchoolDigger. Its proficiency rates in English Language Arts, Mathematics, and Science are significantly lower than the state and district averages. Additionally, the school has a very high chronic absenteeism rate, reaching as high as 75.2% in the 2022-2023 school year, and its four-year graduation rates have fluctuated between 75.6% and 89.6% over the past few years, which are lower than the state and district averages. The school's student subgroups, such as female, male, Hispanic, and low socioeconomic status students, also consistently rank in the bottom 20% of California high schools, indicating significant achievement gaps.

In comparison, the nearby Castro Valley High School, a traditional high school in the same district, consistently ranks in the top 10% of California high schools and has much higher proficiency rates, graduation rates, and lower dropout and chronic absenteeism rates. The high rates of chronic absenteeism and dropout at Redwood Continuation High suggest that there may be underlying issues, such as student engagement, social-emotional support, or alternative educational pathways that need to be addressed. Addressing these challenges will require a comprehensive approach that considers the specific needs of Redwood Continuation High's student population and implements targeted interventions to support their academic and personal growth.

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.
