E. J. Marshall Elementary, Chino CA

Original Research by School Decision on E. J. Marshall Elementary

E. J. Marshall Elementary is a small school serving kindergarten through sixth grade in Chino, a rapidly growing mid-size city in the western Inland Empire of San Bernardino County. The school sits in a community undergoing substantial residential expansion, with new housing built largely on former dairy and agricultural land; much of that development is concentrated in The Preserve, a master-planned community with its own schools and civic spaces.

The school's enrollment is modest, with roughly balanced cohorts across grades. A substantial share of students qualify for free or reduced-price lunch, and the student body is predominantly Hispanic, with small Asian and white populations. Specific counts for English learners and students with disabilities were not available from the data provided.

On state assessments administered in 2024-25, E. J. Marshall's results show proficiency in the lower half of the range. In English language arts, the school's overall proficiency was about a half; third and fourth graders performed at roughly that level, fifth graders notably above it, and sixth graders somewhat below it. Mathematics proficiency was lower, hovering around two-fifths overall. Results dropped notably in the upper elementary grades: third graders reached about half proficiency in math, but that fell to under a third by grade five and again by grade six. Science testing (grade five only) showed proficiency well below math and ELA. The school has only one year of assessment data, so trends cannot yet be assessed.

Relative to districts in San Bernardino County as measured by overall proficiency across tested subjects and grades, E. J. Marshall sits in the top quartile. That positioning reflects how the school compares on a composite metric; individual subjects and grades tell a more granular story of uneven performance.

The parent district, Chino Valley Unified, has implemented a mathematics and professional learning communities framework focused on evidence-based practice. The district reported measurable academic gains in recent years, with math and ELA proficiency rising faster than the state average and narrowing achievement gaps. That systemic context is part of what shapes classroom instruction here.

A parent considering E. J. Marshall should weigh the school's current proficiency results against the district's recent trajectory and the specific interventions underway. The sharp drop-off in math proficiency from grade three onward may warrant direct conversation with the school about what students encounter as they move into the upper elementary grades. The school's socioeconomic context and language landscape are typical of schools in this part of Chino. A parent may want to look into further detail with the school about curriculum, teaching methods, student support for struggling learners, and how the school addresses the widening proficiency gaps as students advance.

Graduation rate (ACGR) reflects the federally published Adjusted Cohort Graduation Rate for the most recent year available. We refresh this data annually at the close of each academic year in June. The federal source publishes a banded rate (for example, "90-94%") instead of an exact number for cohorts small enough to risk identifying individual students. The state distribution chart, where shown, plots every school in the state with a published rate or band; schools whose rate is federally suppressed are excluded. Where the federal source publishes a band rather than an exact rate, the school is placed within its band using a stable, ID-derived offset, so its position is consistent across visits.
