Arroyo Elementary

Summary:

Arroyo Elementary is a public K-8 school in Ontario, California, serving a student population of 467. The school is part of the Ontario-Montclair School District, which has a 2-star rating from SchoolDigger.

Arroyo Elementary stands out for its significantly higher percentage of Hispanic students (89.51%) compared to nearby schools, which range from 69.62% to 91.35% Hispanic. However, the school's academic performance, as measured by Smarter Balanced Assessments, is generally lower than the district and state averages. For example, in 2022-2023, the percentage of students proficient or better in English Language Arts ranged from 10.53% (4th grade) to 48.94% (7th grade), compared to the district average of 40.5% and the state average of 46.66%. In Mathematics, the proficiency rates ranged from 16% (7th grade) to 30.23% (3rd grade), compared to the district average of 30.32% and the state average of 34.62%. Additionally, Arroyo Elementary has a significantly higher chronic absenteeism rate of 28.3% in 2022-2023, compared to the nearby schools, which range from 13.9% to 32.4%.

Arroyo Elementary's performance has consistently ranked in the bottom half of California elementary schools over the past decade, suggesting persistent challenges in improving academic outcomes. The school's high percentage of economically disadvantaged students (85.22% receive free or reduced-price lunch) and the high chronic absenteeism rate may be contributing factors to the lower academic performance. Compared to nearby schools, such as Edison Elementary, which is only 1.7 miles away, Arroyo Elementary has significantly lower proficiency rates in both English Language Arts and Mathematics, as well as a higher chronic absenteeism rate.

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.
