Walter Zimmerman Elementary

Summary:

Walter Zimmerman Elementary is a public elementary school in Bloomington, California, serving 559 students in grades K-6 as part of the Colton Joint Unified School District. However, the school faces significant challenges, including high chronic absenteeism, low academic performance, and disparities in student subgroup outcomes.

Walter Zimmerman Elementary has seen a sharp increase in chronic absenteeism, rising from 9.7% in 2017-2018 to 31.8% in 2022-2023, which is notably higher than nearby schools like Palmetto Elementary and Dolores Huerta International Academy. Academically, the school's proficiency rates in English Language Arts and Mathematics are consistently lower than the Colton Joint Unified School District and the state of California averages, with only 34.87% of students proficient or better in ELA and 18.69% in Mathematics in 2023-2024.

The school's student subgroups, such as English Language Learners, Special Education students, and Disabled students, also perform significantly worse than their peers across the state. Additionally, Walter Zimmerman Elementary has an extremely high percentage of students from low socioeconomic backgrounds, with 94.99% of students qualifying for free or reduced-price lunch in 2022-2023, which is much higher than the nearby schools. Addressing these challenges will require a comprehensive, data-driven approach that leverages the strengths of higher-performing schools in the area and targets the specific needs of the school's 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.
