River Islands Technology Academy II

Summary:

River Islands Technology Academy II is a public charter elementary school serving 993 students in grades K-8 in Lathrop, California, a city within the Manteca Unified school district. This high-performing school consistently outperforms the state average in English Language Arts/Literacy and Mathematics, with particularly strong proficiency rates in 5th-7th grade ELA and 6th grade Math.

The school's academic excellence is especially notable for its African American and English Language Learner student populations, which rank in the top 5-10% of California elementary schools. However, the school's performance for Asian, White, and Multi-racial students is relatively lower, suggesting a need to examine practices to ensure equitable outcomes for all groups. With a chronic absenteeism rate of 19.1% and a relatively low percentage of free and reduced-price lunch recipients at 34.04%, River Islands Technology Academy II stands out as a model of academic success in the region.

The school's proximity to several lower-performing Manteca Unified elementary schools presents an opportunity for River Islands Technology Academy II to serve as a model and potentially collaborate to improve educational outcomes in the broader community. With its consistent academic excellence and effective strategies for supporting historically underserved populations, the school may be well-positioned to expand its reach or share best practices with neighboring schools.

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.
