These measure different things: this figure is spending attributed to this campus, while district-wide figures also include central administration, districtwide programs, and the state's pension contributions made on the district's behalf — costs that never get assigned to a single school. The district number runs higher at nearly every school, not just this one.
$163 per student arrives as federal Title funding — a measure of concentrated need, not school quality.

What should I do next?
Worth a school visit
Ask what the school is working on next. Strong numbers tell you where a school is, not where it's going.
- Ask whether the tour can step into a working classroom — watch how the teacher handles a student who's stuck.
- Ask to tour while school's in session, and notice how hallways and transitions feel — culture shows up between classes, not just in them.
- Ask how the school communicates with families when a child starts to struggle.
- Ask what a typical day looks like for a new student in the first few weeks.
Questions
Frequently asked questions
Is Delta Keys Charter a good high school?
Delta Keys Charter has a Scope Score of 22 out of 100, placing it in the 54th percentile of California alternative high schools and ranked #52 in that group. This is a rank inside that group, not a statewide one: SchoolScope compares alternative schools with one another rather than with California's comprehensive campuses, so it cannot be read against a statewide figure. Why these schools are ranked separately. 10.0% of students exceeded the state standard on the 2025 CAASPP assessment, which is 9.8 percentage points below the California average of 19.8%. The Scope Score weights 7 dimensions for high schools: graduation rate (25%), exceeded standard (22%), college/career readiness (20%), met or exceeded (proficient) (18%), chronic absenteeism (5%), suspension rate (5%), and ELPAC English Learner proficiency (5%). Data source: California Department of Education CAASPP 2025, analyzed by SchoolScope.
What are Delta Keys Charter's CAASPP test scores?
On the 2025 CAASPP Smarter Balanced Assessment, 32.7% of students at Delta Keys Charter met or exceeded the state standard in ELA and Math combined, and 10.0% exceeded it. The gap between those numbers matters: 22.7% of students are at the proficiency floor, while 10.0% went beyond it. Most rating sites report only the combined "proficient" number. SchoolScope surfaces the exceeded-vs-met split because it shows how many students go beyond the standard rather than only meeting it. 110 student-subject combinations were assessed.
How does Delta Keys Charter rank among California alternative schools?
Delta Keys Charter ranks #52 among California alternative high schools by Scope Score, placing it in the 54th percentile. This is a rank inside that group, not a statewide one: SchoolScope compares alternative schools with one another rather than with California's comprehensive campuses, so it cannot be read against a statewide figure. Why these schools are ranked separately. This ranking is based on a weighted composite of 2025 CAASPP test performance (exceeded and met rates), chronic absenteeism, and suspension rate. Unlike single-number ratings, the Scope Score shows what drives the ranking so parents can decide what matters most to their family. See full methodology.
What is the attendance and school culture like at Delta Keys Charter?
8.8% of students at Delta Keys Charter are chronically absent (missing 10% or more of school days), which is better than the California average of 23.1%. The suspension rate is 0.8%, indicating a low-discipline-incident environment. SchoolScope includes these culture metrics in the Scope Score because they reflect day-to-day school experience in ways test scores alone cannot.
How does Delta Keys Charter compare to other schools in Tracy?
Delta Keys Charter scores 22/100 (54th percentile) among California alternative high schools. This is a rank inside that group, not a statewide one: SchoolScope compares alternative schools with one another rather than with California's comprehensive campuses, so it cannot be read against a statewide figure. Why these schools are ranked separately. To compare with nearby schools, SchoolScope shows the same metrics side by side: exceeded rate, proficiency, growth trajectory, and school culture indicators. The school serves 125 students. Use the schools in Tracy page or the map view to compare all high schools nearby.
How does Delta Keys Charter serve low-income and underrepresented students?
At Delta Keys Charter in Tracy, 36.4% of low-income students met or exceeded the ELA standard in 2025, compared to 27.4% district-wide and 38.2% statewide. Delta Keys Charter outperforms its district average for low-income students by 9.0 percentage points in ELA. Other subgroups: Low-Income students (40.9% Math proficient); Hispanic students (26.5% ELA proficient). The largest proficiency gap is 9.7 percentage points for english learner students. Data source: California Department of Education, CAASPP 2024-25. 44 students tested. SchoolScope shows disaggregated test scores by demographic subgroup so you can see how a school performs for your child's specific group — not just the school-wide average. Subgroup data is context, not part of the Scope Score: we don't penalize schools for who they serve. See our equity approach.
