Original Research by School Decision on American Charter Schools Foundation D.b.a. Estrell (79873)
American Charter Schools Foundation d.b.a. Estrella is a single-school charter district serving high school grades in Avondale, Arizona, a suburb within Maricopa County. The district operates one school, Estrella High School, and its enrollment is small, with a student body that is predominantly Hispanic and includes a substantial Black population, along with small numbers of White, Native American, Native Hawaiian or Pacific Islander, and multiracial students. The district’s grade span is ninth through twelfth, so it functions as a standalone high school rather than a full K–12 system.
Public academic performance data is absent for this district. No state assessment results, no proficiency rates across subjects, and no four-year graduation rate are available in the sources we reviewed. This is not because testing does not apply—Arizona tests high school students in several subjects—so the gap is a meaningful one for families trying to assess academic outcomes. Without that information, a parent cannot evaluate how students are performing in core areas or whether the school meets state benchmarks. The district also did not report figures for free or reduced-price lunch eligibility, special education identification, or English learner status, so the level of student need and the supports available are not clear from the data.
One metric that is reported is chronic absenteeism. The rate sits at the highest possible level, placing the district in the bottom quartile among Maricopa County’s districts. This signals that nearly every student is missing a significant number of school days, a pattern that can deeply affect instruction and student progress. A parent would want to understand the causes behind this figure and what the school is doing to improve attendance, as it is a central indicator of student engagement and school climate.
On the resource side, per-pupil current spending falls in the upper range compared to other districts in Maricopa County. That may reflect the costs of running a small charter high school, but without details on how those funds are used—staffing ratios, course offerings, extracurricular programs—the spending figure alone does not tell a family what they are getting for it. We looked for information on curriculum, dual-enrollment options, college and career pathways, or special programs offered by the school, but none was available. Likewise, no discipline data, teacher qualifications, or student-teacher ratios are reported.
The district’s governance is charter-based, meaning it operates independently of the local public school district. It is a single-school entity, so all administrative and instructional leadership is concentrated at Estrella High School. The school’s status is listed as open.
Because so little is publicly documented about academics, graduation outcomes, programs, and student support, this district is difficult to assess from the outside. A family considering Estrella High School would need to contact the school directly for the most basic information: test results, graduation rates, course catalog, college acceptance history, attendance interventions, and any special education or language services. The chronic absenteeism rate is a clear point of concern, but the school may have explanations or improvement efforts that are not captured in the data. Without a fuller picture, the district presents as a very small charter high school whose current public record is too sparse to give a confident read on academic quality or peer environment.
