Mariposa Elementary

Summary:

Mariposa Elementary is a public elementary school in Ontario, California, serving students from kindergarten to 6th grade. The school has seen a decline in its statewide ranking over the past several years, and its performance has been consistently rated 1 or 2 stars out of 5 by SchoolDigger.

Mariposa Elementary faces several challenges, including a high chronic absenteeism rate, lower-than-average test scores in English Language Arts, Mathematics, and Science, and uneven performance across different student subgroups. The school's Hispanic, low socioeconomic status, and disabled student populations have consistently underperformed compared to their peers in the Ontario-Montclair School District and the state. In contrast, the school's English Language Learner students have performed relatively well, ranking in the top 25% of California elementary schools in this category.

Interestingly, Mariposa Elementary's performance is generally lower than most of the nearby schools in the Ontario-Montclair School District, such as Berlyn Elementary, Central Language Academy, and Edison Elementary, which have higher test scores, lower chronic absenteeism rates, and better overall performance. The exception is Del Norte Elementary, which has similar or slightly lower performance metrics compared to Mariposa Elementary.

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.
