Tioga High

Q: Is Tioga High a good school?

Tioga High ranks 1716 th of 2323 California high schools. SchoolDigger rates this school 1 star out of 5.

Summary:

Tioga High is a small public high school located in Groveland, California, serving grades 9-12 with a total enrollment of 47 students. The school is part of the Big Oak Flat-Groveland Unified School District, which is ranked 1097 out of 1568 districts in the state and has a 2-star rating from SchoolDigger.

Tioga High has consistently ranked in the bottom half of California high schools, with its statewide ranking ranging from 898 to 1716 over the past several years. The school's academic performance, as measured by standardized test scores, is significantly below the state and district averages across all subject areas. Additionally, Tioga High has experienced high dropout rates, ranging from 11.8% to 27.8%, and struggles with chronic absenteeism, with rates as high as 86.4% in the 2021-2022 school year. The school's four-year graduation rates have also shown a concerning decline, from 88.2% in 2020-2021 to 61.1% in 2022-2023.

When compared to nearby high schools, such as Don Pedro High, Tioga High performs significantly worse across various metrics, including test scores, graduation rates, and chronic absenteeism. For example, Don Pedro High had a 76.5% four-year graduation rate in 2022-2023, compared to Tioga High's 61.1%. Tioga High's small student population and relatively low student-to-teacher ratio suggest that the school may have access to more individualized attention and resources, but this does not appear to translate into improved academic outcomes for the students, particularly for specific subgroups like male and white students.

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.
