Las Lomas High

Summary:

Las Lomas High is a public high school located in Walnut Creek, California, serving grades 9-12 with a total enrollment of 1,571 students. This exceptional school is part of the Acalanes Union High School District, which is ranked 68th out of 1,568 districts in California and has a 5-star rating from SchoolDigger.

Las Lomas High consistently ranks in the top 10% of California high schools, with a ranking between 77 and 192 out of over 2,000 schools in recent years, and has maintained a 5-star rating from SchoolDigger. The school's performance is particularly strong across various student subgroups, with its multi-racial and Hispanic student populations ranking in the top 5-10% and top 10-15% of California high schools, respectively. Las Lomas High also boasts a high four-year graduation rate, ranging from 95.6% to 97.7% in recent years, and a low dropout rate, ranging from 1.3% to 3.3%, both well above the state average.

When compared to other high-performing schools in the area, such as Campolindo High and Acalanes High, Las Lomas High maintains a clear advantage in academic performance. However, the school could potentially benefit from additional support for its Asian and White student populations, as well as its English Language Learner and Low Socioeconomic Status student populations, to further improve their academic outcomes. Additionally, the school has experienced a slight increase in chronic absenteeism rates in recent years, which is worth monitoring to ensure continued student success.

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.
