Colonial Heights, Stockton CA - Test Scores & Data

Original Research by School Decision on Colonial Heights

Colonial Heights is a kindergarten through eighth-grade regular public school in Stockton, serving a student body that is economically challenged and ethnically diverse. The school enrolls a small to mid-sized cohort across nine grades, with a substantial share of students qualifying for free or reduced-price lunch. The racial and ethnic makeup is varied, with Hispanic students representing the largest group, followed by Asian and white students, with Black, Pacific Islander, and Native American students also represented.

Academic performance at Colonial Heights reflects significant learning gaps across tested subjects. In English Language Arts, proficiency rates cluster in the low range, with fourth grade showing the strongest result at around two-fifths of students meeting standards, while third grade and eighth grade each show proficiency rates in the low twenties. In mathematics, performance is notably lower still, with only around one-third of fourth graders meeting standards and proficiency rates in the third grade and lower grades hovering around one-fifth or less. By the upper grades, math proficiency drops further, with sixth, seventh, and eighth grade each showing proficiency well below one-fifth of students. Science proficiency in grades five and eight is similarly low, in the low teens to upper teens. This pattern of lower proficiency across the board, and particular weakness in mathematics as students progress, positions Colonial Heights below the midpoint for overall proficiency relative to districts in San Joaquin County.

The school's test results come from California's CAASPP Smarter Balanced summative assessments in English Language Arts and mathematics, grades three through eight, and from the California Science Test in grades five and eight. These are the state's primary accountability measures for elementary and middle schools. A parent may want to look into further with the school what instructional strategies and support systems are in place to address the math proficiency gap, especially in the upper grades where the decline is steepest.

The housing market in the school's zip code reflects broader Stockton affordability. Home values are substantially lower than California's state average and considerably below the national benchmark, making homeownership more attainable for families with modest incomes. Rental costs are similarly modest relative to national standards. The ratio of rent to household income falls at a level that is reasonable by national measures, though mortgage costs relative to typical income in the area run higher. This affordability context means Colonial Heights draws families for whom Stockton represents a housing market where their income stretches further than in much of the state.

Stockton itself is a large inland city in California's San Joaquin Valley, with a mixed-use character blending a historic downtown civic core, residential neighborhoods of varying density, and suburban outlying tracts. The city has long served as a processing and distribution center for surrounding farmland, giving it an agricultural and port-city identity. The economy spans transportation and logistics, healthcare, agriculture, education, and government, with e-commerce and distribution centers representing the fastest-growing sector. Most of Stockton is car-dependent, though some central neighborhoods offer pedestrian-friendly streets and transit options. Public life is anchored by the downtown library system, regional bus transit, and public parks. The city is experiencing modest housing appreciation and growing residential development downtown, particularly in affordable and mixed-income housing. Colonial Heights sits in one of these residential neighborhoods, serving a local student population drawn from Stockton's working and lower-income families.

No data on graduation rate, chronic absenteeism, staffing, or attendance were available for this elementary and middle school, as those metrics either apply only to high schools or fall outside the state's standard reporting framework for K-8 schools.

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.
