Casa Grande High

Summary:

Casa Grande High is a public high school located in Petaluma, California, serving grades 9-12 with a total enrollment of 1,710 students. The school is part of the Petaluma Joint Union High School District, which is ranked 447 out of 1,568 districts in California and has a 4-star rating from SchoolDigger.

Casa Grande High has consistently maintained a 4-star rating from SchoolDigger over the past several years, with its statewide ranking ranging from 290 to 548 out of over 2,000 California high schools. The school outperforms the district and state in academic areas like English Language Arts, Mathematics, and Science, with 61.52%, 25.67%, and 37.34% of all students proficient or better, respectively. Additionally, Casa Grande High has a strong four-year graduation rate, ranging from 89.9% to 94.9% over the past five years, and a relatively low dropout rate compared to the state average.

While Casa Grande High's overall performance is strong, the school faces some challenges, particularly in addressing the increasing chronic absenteeism and the performance gaps among certain student subgroups. Compared to nearby schools, Casa Grande High generally outperforms other district schools, but the Credo High charter school, located approximately 7 miles away, consistently outperforms Casa Grande High in academic measures. To build on its strengths and address these areas of concern, Casa Grande High could implement targeted interventions, investigate the root causes of chronic absenteeism, and analyze the practices of high-performing schools in the region.

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.
