Joe Serna Junior Charter

Summary:

Joe Serna Junior Charter is a public charter elementary school serving 357 students in grades K-8 in Acampo, California, which is part of the Lodi Unified School District.

Joe Serna Junior Charter consistently outperforms the Lodi Unified School District and the state of California in English Language Arts (ELA) and Mathematics proficiency rates across all grade levels. For example, in 2023-2024, 49.57% of Joe Serna Junior Charter students were proficient or better in ELA End-of-Course, compared to 37.78% for Lodi Unified and 47.04% for California. The school's Hispanic students and English Language Learner (ELL) students also significantly outperform their counterparts in the district and state. However, the school has seen a concerning increase in chronic absenteeism, from 2.7% in 2018-2019 to 11.9% in 2022-2023, which is still lower than the district and state averages.

Compared to nearby schools in the Lodi Unified School District, Joe Serna Junior Charter outperforms most in both ELA and Mathematics proficiency rates, with the exception of Erma B. Reese Elementary, which has slightly higher proficiency rates in some grade levels and subjects. Joe Serna Junior Charter's student-teacher ratio of 19:1 is lower than most of the nearby schools, which may contribute to its stronger academic performance. Despite the school's high performance, it faces challenges related to its high percentage of economically disadvantaged students, which could be contributing to the increase in chronic absenteeism.

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.
