Cobblestone Elementary

Summary:

Cobblestone Elementary is a public elementary school located in Plumas Lake, CA, serving 546 students in grades K-5. It is part of the Plumas Lake Elementary School District, which is ranked 548 out of 1,568 districts in California and has a 3-star rating from SchoolDigger.

Cobblestone Elementary consistently outperforms the Plumas Lake Elementary District and the state of California in standardized test scores across various grade levels and subjects. In the 2023-2024 school year, the school had higher proficiency rates than the district and state in English Language Arts (ELA) for all grade levels, with the 5th-grade ELA proficiency rate being 56.7% compared to 57.98% for the district and 47.37% for the state. The school's performance for its Hispanic and low socioeconomic status (SES) student populations is particularly strong, ranking in the top 25% and top 35% of California elementary schools, respectively. However, the school's performance for its White and multi-racial student subgroups is relatively weaker, ranking in the bottom 25% of California elementary schools.

While Cobblestone Elementary's academic performance is generally stronger than the nearby schools within the same district (Rio Del Oro Elementary) and other districts, the school has seen a significant increase in chronic absenteeism, from 1.4% in 2018-2019 to 12.6% in 2021-2022, before decreasing to 7.8% in 2022-2023. This trend is concerning and may impact the school's academic performance if not addressed. Overall, Cobblestone Elementary stands out as a strong-performing school within its local context, with a consistent track record of academic achievement, but the school's performance disparities among student subgroups and the recent increase in chronic absenteeism are areas that warrant further attention and improvement.

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.
