Del Sur Senior Elementary

Summary:

Del Sur Senior Elementary is a public elementary school located in Lancaster, CA, serving grades K-8 with a total enrollment of 741 students. The school faces several key challenges, including high chronic absenteeism rates, low academic achievement, and struggles to support certain student subgroups.

Del Sur Senior Elementary has seen a significant increase in chronic absenteeism rates, rising from 10.0% in 2017-2018 to 27.1% in 2022-2023, which is notably higher than the Westside Union Elementary District and state averages. The school also consistently underperforms the district and state averages in Smarter Balanced Assessments for English Language Arts/Literacy and Mathematics across all grade levels. For example, in 2023-2024, only 32.73% of Del Sur Senior Elementary students were proficient or better in English Language Arts/Literacy, compared to 44.95% for the district and 47.04% for the state. In Mathematics, the school's proficiency rate was just 19.96%, while the district and state had 31.25% and 35.54%, respectively. The school's performance in CAST Science assessments is also below the district and state averages.

When compared to other schools in the Westside Union Elementary District, Del Sur Senior Elementary generally underperforms its peers, particularly in terms of test scores and chronic absenteeism rates. However, some nearby schools, such as Gregg Anderson Academy and Quartz Hill Elementary, demonstrate significantly higher academic achievement and lower chronic absenteeism rates. The high percentage of students from low-income families at Del Sur Senior Elementary, as indicated by the free and reduced-price lunch rates, suggests that the school may face significant socioeconomic challenges that could be impacting student performance.

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.
