Original Research by School Decision on Combs High School
Combs High School is the only comprehensive high school serving the J.O. Combs Unified School District in San Tan Valley, a fast-growing, car-dependent bedroom community about an hour southeast of Phoenix. The school serves grades eight through twelve and enrolls a student body that is predominantly white, with a substantial Hispanic population making up roughly a third of students. Smaller shares of Black, Native American, Asian, multiracial, and Native Hawaiian or Pacific Islander students are also represented.
Academically, the available state testing data is limited. For the most recent year, science results at the eighth-grade level were suppressed and so are not reported here, which is a gap that families may want to discuss directly with the school. The school does have two years of proficiency data in English language arts and math for all grades combined. That data shows proficiency rates in both subjects that are in the range of about a third to two-fifths of students meeting the state standard. Those figures point to an academic environment where a majority of students are not yet reaching the proficiency benchmark, a pattern that families considering the school should weigh alongside the full picture of course offerings and student support.
The school serves a large high school population for its grade band and is the main destination for students in the district after they leave its elementary and middle schools. The community context of San Tan Valley matters here. San Tan Valley is overwhelmingly residential, with no traditional downtown, and most residents commute to jobs elsewhere in the Phoenix metro area. The area has grown very rapidly in recent years, and a 2025 vote to incorporate as a municipality signals a shift toward more local governance and services. Housing values in the area are in line with national averages, and the typical commute is long, reinforcing the bedroom-community character.
The J.O. Combs Unified School District recently approved a multi-year strategic plan built around student achievement, culture and climate, operational excellence, and community engagement. In late 2024, voters passed a maintenance and operations budget override that provides additional local funding for teacher and staff pay, special education, arts, music, physical education, class size management, and extracurricular activities. That infusion of local dollars is a concrete sign of community investment in the district and may influence program availability and staffing at the high school going forward.
Combs High School does not have reported data for several dimensions that many families consider, including the share of students qualifying for free or reduced-price meals, special education enrollment, English learner status, chronic absenteeism, discipline rates, staffing ratios, and the graduation rate. These are significant gaps, and a parent who wants a full picture of student support, school climate, and outcomes will need to seek that information directly from the school or district. The comparison set available for this school is relative to high schools in Pinal County, but the school's own comparison metrics were not applicable because the core proficiency and graduation data points were missing, so no county-level positioning is possible from this dataset.
For families looking at Combs High School, the strongest available signals are the district's recent financial and planning commitments, the school's size and demographic composition, and the broader community context of rapid growth and commuter-oriented living. The testing data that is available suggests that overall proficiency in core subjects is modest, and the many missing data points mean that a careful, in-person inquiry with the school about student outcomes, support services, and school climate is essential. The school is clearly the central high school in its growing district, and the community's willingness to pass additional funding suggests a level of local engagement that could shape its trajectory.
