Arroyo Elementary

Summary:

Arroyo Elementary is a public elementary school in Ontario, California, serving 467 students in grades K-8. The school is part of the Ontario-Montclair School District, which is ranked 793 out of 1,568 districts in the state and has a 2-star rating from SchoolDigger.

Arroyo Elementary consistently performs below the district and state averages in standardized test scores across all grade levels and subject areas, with proficiency rates around 30-40% lower than its peers. The school also has a significantly higher chronic absenteeism rate, ranging from 28.3% to 28.8% in recent years, compared to the district's average of 13-30%. Additionally, Arroyo Elementary has a very high percentage of students eligible for free or reduced-price lunch, ranging from 65.52% to 93.52%, which is substantially higher than the other schools in the district.

Compared to nearby schools, such as Edison Elementary, which outperforms Arroyo Elementary by a significant margin in standardized test scores, Arroyo's performance is relatively poor. The high chronic absenteeism rate and the large proportion of students from low-income families suggest that socioeconomic factors may be significantly impacting the school's performance. Addressing these challenges through targeted interventions and support could be crucial in helping Arroyo Elementary improve and better serve its students.

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.
