Tully C. Knoles, Stockton CA - Test Scores & Data

Original Research by School Decision on Tully C. Knoles

Tully C. Knoles is a kindergarten-through-eighth-grade public school in Stockton, California, part of the Lincoln Unified School District. It sits in a city shaped by logistics and agriculture, affordable relative to the Bay Area coast, with a housing market that is publicly reported as normalizing after a period of constrained supply. Home values in the surrounding zip code run well below the California statewide median, though they remain above the national midpoint, and rents have edged upward recently.

The school draws a student body that is predominantly Hispanic, with meaningful shares of white, Asian, and Black students and smaller multiracial and other groups. A very large share of students qualify for free or reduced-price lunch, placing the school in a high-need economic context by any measure. Specific data on English learner rates and students with IEPs were not available in the data provided.

State test results from the 2024-25 CAASPP assessments tell a mixed and largely concerning story. In English language arts, third graders scored above the midpoint for proficiency, which stands out as a genuine bright spot across the grade band. From fourth grade onward, ELA proficiency falls sharply and remains low through seventh grade, recovering somewhat by eighth grade but still well below the statewide majority. The pattern in math is more pronounced: third-grade math proficiency reaches roughly the midpoint, then drops steeply from fourth grade onward, with upper-elementary and middle grades showing very low rates of students meeting the standard. Science results, tested in fifth and eighth grades, are similarly low. On the overall proficiency index relative to districts in San Joaquin County, Knoles sits below the midpoint among the county's comparable entities, though it is not at the bottom of that distribution. A parent would reasonably want to ask the school and district directly about what interventions or support structures are in place for students in the middle grades, where the data shows the sharpest gaps.

Trend data is limited to a single year, so it is not possible to characterize whether results are improving, declining, or holding steady. A social studies assessment result from over a decade ago is also in the record but is too old to inform a current picture.

Because Knoles serves only through eighth grade, there is no graduation rate or AP course data, and those metrics do not apply here. Program details were not available in the data provided.

The school is in Stockton, a large inland city in the San Joaquin Valley. The city is car-dependent in most neighborhoods, though central areas are more walkable, and the Regional Transit District runs an extensive bus network including Bus Rapid Transit corridors. Major employers span Amazon logistics, healthcare, agriculture, and government, giving the regional economy a broad base. The Cesar Chavez Central Library offers multilingual collections and community programming, and the Haggin Museum anchors Victory Park. Affordable housing development is active downtown, and the city's Housing Element was state-certified recently.

For Lincoln Unified as a district, a bond measure with citizen oversight has been publicly noted, but the data did not allow confirmation of timing or scope, so the district brief was left sparse rather than guessed at. No other parent-relevant district changes could be confirmed from the available research.

Families drawn to Knoles likely value its K-8 span, which keeps students in one building through the transition years, and the school's location in a district that is smaller and more suburban in character than the larger Stockton Unified. The academic performance data, particularly the drop-off from third grade onward, is something any prospective family should investigate with the school before enrolling, asking specifically what the school does to sustain early momentum into the upper grades.

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.
