One more thing to know

In grade 11, spring 2026, 10% of students tested in math scored Advanced, against 16% across California. Advanced is the top of the state’s four levels.

Each bar is Golden Valley’s place among 1,498 California public high schools we score. Our calculation from California Department of Education records, updated October 15, 2026.

How to read these bars, and their sources

A place counts the schools out of 100 with a lower figure. The dashed line is the middle. Test results are from spring 2025, grade 11, the latest year with a high school Scope Score. That year the state called these levels Met or exceeded and Exceeded. Attendance counts students who missed 10% or more of school days; fewer is better, so a higher place means fewer such students.

How the group is chosen

The group is every California public high school we score where 36% to 48% of students qualified for free or reduced-price meals in 2024–25. That is within 6 points of Golden Valley’s share. The count includes Golden Valley. Typical means the median: half are higher and half are lower. Schools differ in more than family income, and no score is changed for it. Our calculation from California Department of Education records: state tests (CAASPP), spring 2025, and school meal eligibility, 2024–25.

Over time

Have results changed?

Results in both subjects were similar to 2025. English went from 65% to 62% and math from 29% to 27%.

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.

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 221 of 516 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.

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.

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.

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.
