Delta Elementary Charter, Clarksburg CA

Original Research by School Decision on Delta Elementary Charter

Delta Elementary Charter is a small charter school serving kindergarten through sixth grade in Clarksburg, a rural unincorporated community in southeastern Yolo County. The school enrolls a mixed student body, with roughly equal shares of Hispanic and white students and a moderate proportion of students from families with lower incomes. About a quarter of enrolled students qualify for free or reduced-price lunch.

Academic performance on California state assessments shows proficiency that falls short of the state's expectations across tested grades and subjects. In English language arts, proficiency rates range from under one-third in the early grades to roughly one-half by fifth grade, settling back to around two-fifths by sixth. Math performance follows a similar arc, starting below one-third in grade three and climbing to near one-half by fifth grade before dipping slightly in sixth. Science, assessed only in grade five, shows under two-fifths proficiency. Across all tested subjects and grades, the school's average proficiency rate places it in the top quartile relative to other districts in Yolo County, though this reflects the county's overall academic landscape rather than strength in absolute terms. The one year of testing data available provides no trend information.

The school's enrollment is small, typical for a charter in a rural area, and is fairly balanced across grade levels. Kindergarten enrollment is the largest, which is consistent with the school's role as an elementary provider.

Clarksburg itself is a longtime agricultural and wine-country community with few modern commercial anchors and no conventional downtown. Most residents rent their homes. Daily life centers on a small cluster of community anchors: two churches, a public library, the Holland Market, a volunteer fire department, and the schools themselves. The area's local economy remains built around viticulture and agricultural support rather than a single major employer. The Old Sugar Mill, a historic site that houses wineries and has served as an events venue, has recently changed hands and is in the early stages of new ownership and management. The community sits on the Sacramento River about a short drive south of the state capital. There has been little major new residential development in the area for decades, though some mixed-use redevelopment proposals tied to the Old Sugar Mill site have faced regulatory delays.

Information about the school's program offerings, staffing, special education and English learner services, and discipline practices was not available. Parent-relevant changes in the Delta Elementary Charter District were not found in the search.

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.
