Core Charter, Marysville CA - Test Scores & Data

Original Research by School Decision on Core Charter

CORE Charter is a kindergarten-through-twelfth-grade charter school in downtown Marysville, serving a student body with significant economic need and diversity. It operates as an independent-study and personalized-learning program, a distinct pedagogical model that shapes both the student experience and the academic results.

The school's enrollment spans all grade bands, with a smaller presence in the primary grades and heavier enrollment in middle and high school years. About half of all students qualify for free or reduced-price lunch, and the student population is diverse: the majority are white, with a substantial share identifying as Hispanic, and a minority share across Black, Asian, Native Hawaiian, and multiracial categories. State testing data is available for elementary through middle grades.

In English language arts, results show a clear split by grade level. In grades three and four, proficiency is modest, in the low range. Grade five marks a pronounced jump, with proficiency reaching into the upper-middle range. Grades six and seven hold near that level, and grade eight sits slightly lower but still solidly in the upper-middle band. Math proficiency is lower across the board, with elementary grades showing low results. Middle grades climb notably, with grade seven reaching toward the upper-middle range before dipping somewhat in grade eight. Science results are available for grade five and eight; both sit in the mid range. Across all tested subjects and grades, the school's overall proficiency index places it above the midpoint among districts in Yuba County.

The school's academic profile reflects the independent-study and personalized-learning model. This approach can allow for flexible pacing and student-directed learning pathways, but it also places considerable responsibility on families for engagement and structure. Parents choosing CORE should understand that results in the elementary grades, particularly in math, are low, and that the instructional model differs substantially from a traditional classroom-based school. The jump in performance in grade five and the sustained strength in grades seven and eight in ELA suggest the school may find greater student success as learners mature, though math remains a softer area throughout.

A graduation rate was not available; this may reflect the independent-study design or data-reporting practices specific to charter schools. English learner counts and special education enrollment figures were not reported in the available data. A parent may want to ask the school directly about supports for students with disabilities, English learners, and how the personalized-learning model adapts for students working significantly below grade level.

CORE Charter draws students from Marysville and surrounding areas in Yuba County. The city itself is a small historic river town with a walkable downtown, anchored by Ellis Lake and featuring Gold Rush-era commercial buildings. The local economy rests on government employment, healthcare, education, and the nearby Beale Air Force Base, alongside historical agricultural roots. Housing in the 95901 zip code is modestly valued relative to California state benchmarks, and rents are in the low-to-moderate range, making it a more affordable option than many parts of the state. Marysville is pursuing downtown revitalization and new multifamily housing development, though the city remains quiet and community-focused rather than high-growth.

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.
