Glassbrook Elementary

Summary:

Glassbrook Elementary is a public elementary school in Hayward, California, serving 474 students in grades K-6. The school is part of the Hayward Unified School District, which is ranked 1235 out of 1568 districts in the state and has a 1-star rating from SchoolDigger.

Glassbrook Elementary consistently ranks in the bottom 5% of California elementary schools, with significantly below-average performance on standardized tests across all grade levels and subject areas. In 2023-2024, only 11.55% of Glassbrook students were proficient or better in English Language Arts, compared to 31.29% for Hayward Unified and 47.04% for California. In Mathematics, only 5.99% of Glassbrook students were proficient or better, compared to 19.2% for Hayward Unified and 35.54% for California. The school also faces challenges with high chronic absenteeism, rising from 11.8% in 2017-2018 to 44.7% in 2022-2023, and a high percentage of students from low-socioeconomic backgrounds, with 74.26% qualifying for free or reduced-price lunch.

Glassbrook Elementary's performance is significantly worse than nearby Eden Gardens Elementary, Lorin A. Eden Elementary, and Southgate Elementary, all of which have higher academic achievement, lower chronic absenteeism, and lower percentages of students from low-socioeconomic backgrounds. Glassbrook's performance is particularly low for certain student subgroups, such as Hispanic students and English Language Learners, who rank in the bottom 5-10% of their respective subgroups statewide. The school's declining performance over the past decade, from around the bottom 10% of California elementary schools to the bottom 1% in recent years, is a concerning trend that warrants further investigation and intervention.

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.
