The California School Campus Database records The Bridge Academy on this campus too; it gives each school the whole campus, so this drawing doesn’t show which buildings each uses.

Drawn from OpenStreetMap, inside the campus outline from the California School Campus Database (2025). Volunteers map it, so a new building may be missing. Buildings with no mapped height are drawn one storey high.

A picture of the campus, not an attendance boundary or a rating.

Schools maintain a closed campus policy. For students’ safety, visitors may enter a campus only with the school’s official permission; this drawing implies no permission to enter.

In grade 11, spring 2026, 48% scored Proficient or Advanced in math, against 32% across California.

From spring 2026, the state calls its top two levels “Proficient or Advanced” (formerly “Met or Exceeded”).

Where these figures come fromEach measure’s source, student group and definition
Graduated in four years
2024–25 · 358 of 392 students who started 9th grade together. California Department of Education, adjusted cohort graduation records. Comparison is SchoolScope’s combination of graduates and cohort counts across the reference schools, not CDE’s published state rate.
Ready for college or career (state measure)
2024–25 · 238 of 392 students in the state’s measure. California Department of Education, College/Career Indicator (CCI), overall “Prepared” rate, among the students in the indicator’s group. Prepared is CDE’s overall classification, not AP participation or a college admission rate.
Finished the UC/CSU course list
2024–25 · 215 of 358 graduates finished the UC/CSU course list. California Department of Education, A–G completion records (graduates who met the UC/CSU course requirements). Course completion is separate from college enrollment.
Where students who finished high school went
CDE college-going records, class of 2023. College enrollment is counted for 12 months after finishing high school and matched to college records, so this runs about two years behind. A dash is unavailable, not zero.

From the district’s 2026 attendance boundaries. Shares are our estimate of where the zone’s children live, from 2020 Census child counts, or land area where few children were counted; they describe children living in the zone, not a school’s enrolled students. A boundary doesn’t guarantee placement: transfers, permits, magnets and other programs can change the path. Check your child’s address and current assignment with the district.

Index is where the school's value sits among the California high schools we score, from 0 to 100, where 50 is their average; it is not a percentile. School values are from 2024–25. Chronic absence and suspension are CDE's all-students school rates; the score uses an adjusted version of each that pulls small schools toward the average, so their index can sit nearer 50 than the rate suggests.

A grade the school doesn't teach has no row. “Suppressed” marks a result CDE blanks because fewer than 11 students tested (CDE’s reporting rule); “none tested” marks a grade CDE lists with no students tested; “not on file” marks a result missing from the records we hold. None of them means zero.

AP pathway among CCI Prepared studentsCDE College/Career Indicator · CCI source year 2025 · all students · AP pathway rate 71% · AP-pathway numerator 168 · denominator 238 (CCI Prepared students). This measure uses Prepared students as its denominator, not the whole CCI cohort; it is not an AP exam-taking rate or a count of AP courses offered. That cohort includes all students in the current four-year graduation cohort plus only Prepared fifth-year graduates from the prior cohort. In 2025 the pathway accepts two qualifying AP exams, two qualifying AP courses, or a combination of one of each in different subjects.

CDE's overall Prepared rate is the college-readiness factor in the Scope Score (20% of the high school score). The school rate is 238 of 392 CCI students, not the AP-only pathway or A–G completion rate. The California figure is CDE's statewide CCI student cohort, not an average of SchoolScope's comparable high schools or the SchoolScope school-rank pool.

Source: UC admissions by source school. Dated fall first-year UC applicants, admitted students, and enrollees. GPA is each group's mean weighted, capped high-school GPA for 10th/11th-grade college-preparatory courses. SchoolScope leaves GPA unavailable when several CEEB codes contribute rather than combining their means. UC blanks counts under 5 applicants or under 3 admits or enrollees, shown here as “under 5” or “under 3”; — means unavailable, and a reported zero remains zero. A + marks a partial SchoolScope sum of observed counts, not a complete total; missing contributions may be zero. No admit rate is computed here. Complete, matching counts can support a historical descriptive rate, but do not establish a school's effect or predict individual chances. Series shown from 2016.

How the California mean was selected

SchoolScope starts with its selected California finance records, not every NCES California district. For FY 2020–21, it calculates an unweighted mean of NCES F-33 current expense per pupil. District records contribute once, regardless of enrollment. The calculation keeps records with positive per-pupil current expense, enrollment over 100, CCD agency type 1, and a recorded district name; it excludes names ending in County Office of Education, Department of Education, or Superintendent of Schools. This is a SchoolScope calculation, not a state-published spending average.

These shares are our arithmetic: each group’s dollars divided by the $237,610,873 total of the groups shown, rounded to whole percents by largest remainder so they add up to 100. Dollar amounts are rounded to the nearest dollar, so they can differ from the total by a dollar. SchoolScope groups district-level CDE SACS UserGL actuals from Fund 01, using operating objects 1000–5999 and excluding retiree benefits, food and community services, facilities acquisition, other outgo, and nonagency goals. These shares use that filtered total; they do not exactly break down CDE's official current expense per ADA above. The school-level ESSA figure uses a separate source.
