Covillaud Elementary, Marysville CA

Original Research by School Decision on Covillaud Elementary

Covillaud Elementary is a small public elementary school in downtown Marysville serving kindergarten through fifth grade. The school sits in a compact historic river town north of Sacramento, defined by Gold Rush-era brick buildings and a walkable downtown grid around Ellis Lake. The student body is economically and ethnically mixed. A substantial share of students qualify for free or reduced-price lunch. The enrollment breaks fairly evenly across grades, with slightly more students in the lower grades.

On California's latest standardized assessments, Covillaud's proficiency rates show a clear decline as grade level rises. Third graders in math achieved proficiency at a modest level, but that rate fell sharply by fourth grade and dropped further by fifth grade. The pattern holds in English language arts: third grade saw roughly half the class at proficiency, but fourth and fifth grade rates dropped into the low forties and then to the mid-thirties. Science proficiency in fifth grade was substantially lower still. Across all tested grades and subjects, the school's overall proficiency index sits above the midpoint when compared with other districts in Yuba County, but the downward trajectory within the school as students advance is a real concern. The data available covers only one school year, so there is no trend history to show whether this reflects a persistent pattern or recent movement.

The school's strengths are its location and access. It sits within walking distance of downtown Marysville's civic core, near Ellis Lake and the City library, on local bus routes, and in a community pursuing deliberate downtown housing growth and revitalization. For families in or near Marysville's center, the school offers genuine walkability and proximity to civic life.

The broader district context matters. In March 2024, Marysville Joint Unified voters rejected a bond measure that would have funded facility renovations and a new middle school. That defeat means aging buildings and overcrowding remain unresolved. For elementary families considering the school, this underscores the reality that facility improvements and new capacity are not in the pipeline. Parents may want to ask the school directly about class sizes, condition of classrooms and learning spaces, and what support the district can commit to for upper-elementary math and reading, where proficiency gaps are evident. State testing data does not tell you about English-learner support, special education services, or other school-level programs, so direct conversation with staff would be important before enrolling, particularly if your child needs those services.

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.
