Original Research by School Decision on Winn A. Myers Elementary
Winn A. Myers Elementary sits on North Meridian Avenue in Rialto, a predominantly residential Inland Empire city whose character blends tree-lined suburban streets with a substantial logistics and warehousing corridor south of the freeway. The school serves kindergarten through fifth grade as a regular public school within Rialto Unified, and its enrollment is solidly sized for its grade band. The student body is heavily Hispanic, with smaller shares of Black and white students, and the vast majority of students qualify for free or reduced-price lunch, meaning this is a high-poverty school by any measure. Data on English learner enrollment and students receiving special education services were not available in the materials reviewed.
On the California state assessments, results across grades three through five tell a consistent story. In English language arts, proficiency rates range from roughly the upper twenties in third grade up to the mid-forties by fifth grade, suggesting some upward momentum as students move through the school, though even the strongest grade sits below the state midpoint. Math results are lower across the board, with third and fourth grade in the mid-twenties and fifth grade climbing to the upper thirties. Science, tested only at fifth grade, comes in just below thirty percent. Taken together, the school's overall proficiency index places it above the midpoint among districts in San Bernardino County, which is a genuinely encouraging position given the economic challenges its families face. Parents who want to understand how individual students are progressing against grade-level standards, and what the school is doing to move those numbers, would benefit from a direct conversation with staff.
Multi-year trend data is not available for comparison, so it is not possible from the data in hand to say whether these results represent improvement, stability, or decline from prior years. No graduation rate applies here, as the school ends at fifth grade.
Rialto Unified passed a substantial general obligation bond in November 2022, publicly reported as funding facility upgrades across the district, covering areas like safety systems, science and vocational classrooms, water pipes, roofing, and removal of environmental hazards like asbestos and lead paint. Property owners within district boundaries repay this bond through a property tax, which is worth knowing for families buying in the area. The district also shifted to by-trustee-area board elections beginning with that same election cycle, so families now have a board member representing their specific geographic area rather than the district at large.
On housing, the Rialto zip code carrying this school sits well below the California state median home value, though still meaningfully above the national median. Home values have risen modestly year over year. Rents are also below the state norm, and the estimated monthly cost of carrying a mortgage on a typical local home runs close enough to renting that the gap is narrow. The city itself is growing, with active residential development and a planning framework that encourages higher-density construction along the Foothill Boulevard corridor. Rialto achieved compliance with California's Housing Element requirements in early 2026, a process tied to a multi-year regional housing allocation cycle, which signals continued development pressure in the years ahead.
For daily life, Rialto is a car-dependent city. A Metrolink station on the San Bernardino Line sits near the historic downtown, with bus service provided by Omnitrans, but most errands and commutes rely on the freeway network. The city's largest employer is Rialto Unified itself, with logistics companies, Amazon, FedEx, and Target Distribution among the prominent private employers, reflecting the warehouse-heavy economy of the broader Inland Empire.
For a family weighing this school, the peer environment is economically homogeneous and predominantly Hispanic. Academic proficiency is measurably below state averages, though the school's standing among San Bernardino County districts is not at the bottom. The facility investment coming through the district bond may improve conditions at Myers in the coming years, but the specifics of which campuses are prioritized and on what timeline are worth asking the district directly.
