River Delta High/Elementary (Alternative)

Summary:

River Delta High/Elementary (Alternative) is a public alternative school located in Rio Vista, California, serving grades K-12 with a total enrollment of 28 students. The school is part of the River Delta Joint Unified School District, which is ranked 1214 out of 1568 districts in California and has a rating of 1 star out of 5 by SchoolDigger.

River Delta High/Elementary (Alternative) stands out with its higher graduation rates and lower dropout rates compared to nearby alternative schools like Solano County Special Education and Prospects High (Alternative). However, the school still faces challenges in improving academic performance, as evidenced by its significantly lower proficiency rates in Smarter Balanced Assessments/English Language Arts/Literacy, Smarter Balanced Assessments/Mathematics, and CAST/Science compared to the River Delta Joint Unified School District and the state of California. Additionally, the school has experienced fluctuating chronic absenteeism rates, ranging from 0.0% in 2017-2018 to a high of 54.0% in 2021-2022, before decreasing to 25.6% in 2022-2023.

The school's relatively high percentage of students receiving free or reduced-price lunch, ranging from 45.45% to 60.71% over the past few years, suggests that it serves a population with lower socioeconomic status, which can be a contributing factor to the lower academic performance observed. While River Delta High/Elementary (Alternative) appears to be providing a more supportive environment for its students, there are still opportunities to strengthen the academic curriculum, instructional practices, and strategies to improve attendance and address the unique needs of its 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.
