Original Research by School Decision on Delta Keys Charter
Delta Keys Charter is a small, very senior-focused charter school in Tracy serving nearly a full complement of twelfth graders, a substantial number of eleventh graders, and a handful of tenth graders. The enrollment sits at about a hundred twenty-five students. It is the only K-12 charter listed for New Jerusalem Elementary, the parent LEA.
The student body is predominantly Hispanic, with a majority qualifying for free or reduced-price lunch. The school draws from a community with limited economic advantage; the Tracy area itself is a mix of walkable downtown and car-dependent suburban neighborhoods built around logistics, warehousing, and distribution work, with newer master-planned residential development on the southwest side. Housing costs have softened slightly, and the labor market remains steady, though wages do not stretch as far as they do in higher-income Bay Area communities.
Academic performance data is available only for the current school year. Reading proficiency sits below math, and science proficiency is notably low. The school does not report graduation rate, special education enrollment rate, or English learner rates. Because the school enrolls almost exclusively twelfth and eleventh graders with only two tenth graders, it functions as a senior program rather than a traditional full K-12 school despite its charter authorization. A parent may want to look into the school directly to understand whether this is an alternative pathway for students who have already progressed through earlier grades elsewhere, or a transitional program, or another model entirely, since the enrollment pattern itself is unusual and the data does not explain it.
State assessment results cover only the single year reported and do not show growth or trend. Comparison data with other districts in San Joaquin County is not available because the school's proficiency figures do not align with the standard county comparison metrics.
The school's street address places it on South Koster Road in the southern part of Tracy. No information about programs, course offerings, staffing, discipline practices, or attendance was found in the data provided. No school website was available to consult. The district brief search did not yield parent-relevant recent changes specific to New Jerusalem Elementary.
For a family considering this school, the critical first step would be to contact Delta Keys Charter directly to understand what this program is designed to serve, who typically enrolls, what completion or outcome pathways it offers, and what support services are in place for the student population.
