Sentinel High

Summary:

Sentinel High is a small public high school located in Waterford, California, serving just 21 students in grades 9-12. This school stands out from the surrounding high schools in the region due to its extremely small size, poor academic performance, high rates of chronic absenteeism and dropout, and socioeconomic challenges faced by its student population.

With only 21 students, Sentinel High is one of the smallest high schools in the area, in stark contrast to nearby schools like James C. Enochs High and John H. Pitman High, which have student populations ranging from around 100 to over 2,400. Sentinel High consistently ranks in the bottom 10-15% of California high schools based on the SchoolDigger statewide ranking, with test scores significantly lower than the Waterford Unified School District and state averages. The school also faces alarmingly high rates of chronic absenteeism, ranging from 25% to over 74% in recent years, and a dropout rate fluctuating between 4.5% and 10.5%.

Sentinel High's student population is predominantly Hispanic (57-65%) and White (30-35%), with very few African American, Asian, or other minority students. Additionally, a large majority of the school's students (over 85%) come from low-socioeconomic status backgrounds, as indicated by the high percentage of free and reduced-price lunch recipients. These factors, combined with the school's small size and isolated location within the Waterford Unified School District, which is ranked 982 out of 1,560 districts in California, may be contributing to Sentinel High's persistent struggles and the need for targeted interventions to address the unique challenges faced by this small, high-poverty school.

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.
