Original Research by School Decision on Kaizen Education Foundation Dba Advance U (91329)
Kaizen Education Foundation dba Advance U is a very small charter district in Maricopa County serving kindergarten through third grade. The district operates a single school, South Mountain Preparatory Academy. Because the grade band ends at third grade, the typical academic accountability measures that apply to upper-elementary and secondary schools—such as a graduation rate—simply do not apply here. For that reason, anyone comparing this district to K–12 districts will find those fields absent, and that absence reflects the early-grade nature of the school rather than a performance gap.
The student body is small, with enrollment concentrated in kindergarten through third grade. Hispanic students make up the largest share of enrollment, followed by a substantial share of Black students, with smaller numbers of White, American Indian or Alaska Native, and multiracial students. This composition is a straightforward characteristic of the community the school draws from; there is no good-or-bad framing to attach to it. The district did not report free-or-reduced-price lunch data, special education counts, or English learner counts, so a family would want to ask the school directly about the availability of support services and the share of students who qualify for assistance.
State assessment results for the 2024–25 school year were suppressed for both third-grade and fourth-grade math and English language arts. Suppression occurs when the tested-student count is low enough that an individual student’s result could be inferred. The number of students tested in each subject and grade was very small—roughly a dozen or so per group. Because the district only serves up to third grade, any fourth-grade testing would involve a very small cohort. Parents should understand that the available testing data cannot paint a picture of academic proficiency here; the cohort is simply too small for public reporting. That is not unusual for a school of this size, but it does mean families will need to rely on direct conversations with the school about student progress and classroom instruction.
One area where data is available and stands out is chronic absenteeism. The district’s chronic absenteeism rate places it in the bottom quartile among Maricopa County’s districts. That is a high rate of students missing enough school to affect learning. For a school serving very young children, chronic absenteeism at an elevated level is worth understanding. A parent may want to ask what steps the school takes to support attendance, whether transportation or family engagement factors are at play, and how the school defines and tracks absences.
On the spending side, the district’s per-pupil current expenditure is in the upper range among the county’s districts. A small school often has higher per-pupil costs because fixed expenses are spread over fewer students, so this figure is consistent with the district’s scale. It does not by itself signal additional program depth, but it may reflect the realities of operating a standalone early-grades charter.
The district’s location was not specified in the available data beyond being in Maricopa County. The school, South Mountain Preparatory Academy, is mentioned in the directory but no street address or community context was provided. Searches for recent district changes turned up only basic directory information, so there is no confirmed news about facility moves, leadership shifts, or program expansions to report. The district appears to be a small, early-elementary charter with limited publicly reported performance metrics, making it a place where a family’s direct experience and communication with the school would be especially important in deciding if it fits their child’s needs.
