Original Research by School Decision on Sheridan Allprep Academy

Sheridan AllPrep Academy is a public charter school serving kindergarten through twelfth grade in the small city of Sheridan, Oregon. It operates as part of the Sheridan School District 48J. As a charter school, it offers a distinct governance and educational model within the district, and families choose to enroll there. The school sits in the western Willamette Valley, a former timber and farming community that has diversified over time, with the Federal Correctional Institution, Sheridan, as the city’s largest employer and a federal prison population included in the official town census count.

The school’s enrollment is small for a K-12 campus, and the student body is predominantly white, with a notably smaller share of students from other racial and ethnic backgrounds. Free and reduced-price lunch data was not available in the public record, nor was information on special education or English learner populations, which means a parent may want to ask the school directly about its support for students receiving federally funded services. State testing results are available for most elementary and middle school grades, and they show a mixed picture. On the 2024-2025 state assessments, the school posted its strongest results in fifth-grade English language arts and fifth-grade science, with the majority of students meeting proficiency. In math, the pattern is more variable: by seventh and eighth grade, the share of students scoring proficient is lower, a trend that is common nationally but still worth a close look. Fourth-grade math results were suppressed in the public dataset due to small group size, so no reliable figure is available for that grade.

Because this is the first year of available test data from the current assessment, there is no trend to compare against. The school has not yet built a track record of year-over-year improvement or decline. The composite proficiency index across all tested grades and subjects places Sheridan AllPrep Academy in the top quartile of schools relative to other districts in Yamhill County, a useful position marker when thinking about peer comparison in the local area. A high school graduation rate was not reported, which may reflect the charter school’s reporting structure or grade-level testing configuration; a family with a high school student would want to confirm graduation outcomes directly with the school. Course access data was also missing from the public record, so it is not possible to say from this analysis whether the school offers Advanced Placement, dual credit, or career and technical education pathways for its upper-grade students.

The district itself, Sheridan SD 48J, showed no recent changes in curriculum, pedagogy, programming, or finances that cleared the bar for lasting impact, so this narrative reflects the school’s current standing without reference to any major district shift that would reshape the experience. Sheridan’s housing market shows a typical home value that is below the statewide average and sits at a measured national affordability benchmark, though the cost of renting and owning has been shaped by the same macroeconomic pressures seen across the region.

This is a small charter school that spans all thirteen grades, so a child who starts in kindergarten could theoretically stay on the same campus through graduation. The testing data suggests a school where academic performance is strongest in the early-to-middle elementary years, with some softening in the older middle school grades. The student body is not highly diverse, and the school serves a community whose economy is anchored by a federal prison, agriculture, and timber. A parent considering this school may want to investigate what the upper-grade academic and extracurricular offerings look like, the school’s track record on high school completion, and the specific supports available for any student who needs special education or English language services, since those data points were not available in the public record.

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.
