Original Research by School Decision on Jack Harmon Elementary School
Jack Harmon Elementary School serves students in pre-kindergarten through sixth grade as part of the J O Combs Unified School District in San Tan Valley, a fast-growing residential community in northeastern Pinal County. The school is a regular public elementary campus, not a charter or magnet, and its enrollment is of a size typical for a suburban elementary school serving those grade levels.
San Tan Valley is a bedroom community about an hour southeast of Phoenix. It has no traditional downtown; the built environment is made up of master-planned subdivisions and strip retail along wide arterial roads. The area is car-dependent with minimal walkability and limited public transit. It is one of the fastest-growing places in the country, and in 2025 voters approved a measure to incorporate it as a municipality, signaling a transition from unincorporated census-designated place to city. Housing costs in the area are roughly in line with the state average and above the national figure, reflecting the region's continued growth and demand.
The student body at Jack Harmon is roughly evenly split between White students and Hispanic students, each making up close to half of enrollment. Smaller shares are Black, American Indian, Asian, multiracial, and Native Hawaiian or Pacific Islander. Data on the share of students qualifying for free or reduced-price lunch, as well as the number of students with disabilities or English learner status, was not available, so a parent may want to ask the school about those supports directly.
On state assessments administered in the 2024-25 school year, results varied by grade and subject. In third-grade math, roughly two out of five students scored proficient; in fourth-grade math, a similar share. Third-grade English language arts showed roughly one in four proficient, while fourth-grade ELA showed about half proficient. Fifth-grade ELA results were similar to third grade, and fifth-grade science proficiency was also roughly one in four. Results for fifth- and sixth-grade math and sixth-grade ELA were suppressed due to small group sizes, a common practice when the number of tested students is low. When looking across all tested subjects and grades, the school's overall proficiency index sits above the midpoint among the forty-two school districts in Pinal County.
The school serves only elementary grades, so no graduation rate is reported. No data on chronic absenteeism, discipline rates, or staffing ratios were available in the source materials. Course offerings and program details such as art, music, or enrichment were also not provided.
At the district level, voters in 2024 approved a maintenance and operations budget override that supports teacher and staff pay, special education services, art, music, and physical education programs, as well as class size management and extracurricular activities. The district also adopted a 2024-2029 strategic plan centered on student achievement, culture and climate, operational excellence, and community engagement.
Jack Harmon Elementary sits in a growing suburban area where many families commute to jobs in the Phoenix metro area. The school provides a neighborhood elementary option within a district that has recently secured additional local funding and laid out a strategic direction. Its academic results on state tests are broadly in the middle range of Pinal County districts, with some grade-level variation. Families considering this school may want to look into the areas where data was missing, such as student support populations and specific program offerings, to get a fuller picture.
