Copper Basin

Summary:

Copper Basin is an elementary school serving grades PK-8 in the Florence Unified School District in San Tan Valley, Arizona, with a student population of 640. The school has a racial makeup that is predominantly White (44.69%) and Hispanic (39.22%), and it has consistently ranked in the bottom half of Arizona elementary schools in recent years, with a 1-star rating from SchoolDigger in the 2022-2023 school year.

Copper Basin's academic performance, as measured by standardized test scores, is significantly below state and district averages across all grade levels and subject areas. For example, in the 2022-2023 school year, only 16% of 5th graders and 10% of 8th graders were proficient or better in science, compared to the state averages of 34% and 27%, respectively. The school has also experienced a concerning increase in dropout rates in recent years, rising from 0.9% in 2016-2017 to 5.2% in 2021-2022, which is significantly higher than the state average. Additionally, Copper Basin has a high percentage of students from low-socioeconomic backgrounds, with 58.91% of students qualifying for free or reduced-price lunch in the 2022-2023 school year.

Copper Basin's academic performance is consistently lower than that of nearby schools within the Florence Unified School District, such as San Tan Heights Elementary, Magma Ranch K8 School, and Walker Butte K-8, which generally outperform Copper Basin on standardized tests and have higher proficiency rates. The wide variation in performance across different student subgroups at Copper Basin indicates that the school may need to implement targeted interventions and support programs to address the specific needs of underperforming groups, such as White and Hispanic 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.
