Butterfield Charter

Summary:

Butterfield Charter is an alternative public charter school located in Porterville, California, serving grades K-12 with a total enrollment of 384 students. The school is part of the Porterville Unified School District, which is ranked 974 out of 1,568 districts in California and has a 2-star rating out of 5 from SchoolDigger.

Butterfield Charter has faced significant challenges, with fluctuating four-year graduation rates ranging from 56.6% to 72.9% over the past few years, much lower than the state and district averages of around 85%. The school has also experienced high dropout rates, ranging from 6.0% to 40.5%, and extremely high chronic absenteeism rates, ranging from 46.1% to 85.8%, which are significantly higher than the state and district averages. Butterfield Charter students perform significantly below state and district averages on standardized tests, with proficiency rates in English Language Arts, Mathematics, and Science ranging from 0% to 17.84% across different grade levels and subject areas.

When compared to nearby schools, such as Eleanor Roosevelt Community Learning Center, which has a 92.9% graduation rate and much higher proficiency rates, Butterfield Charter stands out as an outlier in terms of academic performance and student outcomes. The school's high student-teacher ratio, ranging from 14.6 to 25.5, may also be a contributing factor to its challenges. To address these issues, the school and district may need to implement targeted interventions, review and adjust the curriculum and instructional practices, and explore partnerships with community organizations to better support the needs of the 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.
