Sandburg Middle

Summary:

Sandburg Middle is a public middle school located in Glendora, California, serving 701 students in grades 6-8. It is part of the Glendora Unified School District, which is ranked 381 out of 1,568 districts in the state and has a 4-star rating from SchoolDigger.

Academically, Sandburg Middle performs above the state average in English Language Arts/Literacy and Mathematics, but lags behind the district average. In science, the school's performance is closer to the state average but still below the district. The school's Asian and Hispanic student subgroups perform relatively well, ranking in the top half of California middle schools, while the White, Multi-racial, English Language Learner, and Low Socioeconomic Status subgroups lag behind. Notably, Goddard Middle, another Glendora Unified school, consistently outperforms Sandburg Middle in academic assessments.

One area of concern for Sandburg Middle is its rising chronic absenteeism rate, which has increased from 6.2% in 2017-2018 to 20.7% in 2022-2023, higher than the state average. The school also has a relatively high percentage of students receiving free or reduced-price lunch, at 52.92%, indicating a higher proportion of students from low-income families. Addressing these challenges and aligning Sandburg Middle's performance with higher-performing schools in the region, such as Ramona Middle and BP STEM Academy, could help the school achieve greater academic success and better serve its diverse student population.

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.
