Summary

Butterfield Charter is a K-12 alternative public school serving 504 students in Porterville, CA, operating under the Porterville Unified School District, and it serves a student population where the vast majority qualify for free or reduced-price lunch.

Academic performance at Butterfield Charter is significantly below state averages, with only 14% of students proficient in English, 3% in math, and 3% in science for the 2024-2025 school year; these are the lowest scores among comparable nearby alternative schools like Monarch River Academy and Summit Charter Academy, which have much higher proficiency rates. The school spends more per student ($20,846) than most of these neighboring schools, yet this higher investment has not translated to stronger academic outcomes, creating a notable gap between resources and results.

Despite these academic challenges, the school has shown a major positive trend in reducing chronic student absenteeism, cutting the rate from 86% to 25% over three years, and recent graduation rates have improved after a period of volatility. For parents considering an alternative education setting, it's important to note that while Butterfield is making strides in attendance, its academic performance lags behind other local options that serve similar grade levels.
