California is CDE’s statewide math row for each grade, counting every student tested there; the comparisons in the chapters combine these rows for their grades, weighted by students tested (our calculation).

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.

Reading screening in kindergarten through grade 2What the law requires, and what to ask

California law requires schools to screen kindergartners through second graders for reading difficulties every year, with some exceptions. You get notice at least 15 days before, results within 45 days, and can opt out in writing.

Kindergartners can’t be screened before the 91st school day; transitional kindergarten isn’t covered.

If screening shows your child may be at risk for reading difficulties, the school must provide supports. That result isn’t a diagnosis, and screening can’t be used to delay a special-education evaluation.

Ask how many K–2 students screening found at risk last year, and how many got extra reading help.

Where these figures come fromEach measure’s source, student group and definition

Graduated in four years: 2024–25 · 129 of 132 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 · 60 of 133 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 · 34 of 129 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.

These records don’t show the school’s effect on admission. A student can apply to several campuses, so campus counts don’t add up to the total. CSU withholds counts under 6; a dash is unavailable. Students who reach CSU from a community college aren’t counted here. Source: CSU High School Success dashboard.

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.

CDE reports scale-score points against the state’s expected score — not a percentage or percentile. The table keeps the group records SchoolScope imported for this school, including rows below our narrative display threshold. Muted rows have fewer than 30 students with a valid growth score. SchoolScope uses that threshold for the shorter narrative view; the reported values stay visible here. “Not categorized” means this imported CDE row has a growth value without a performance category. Long-term English learner counts cover grades 6–8 only (CDE’s rule), so that row is not comparable to the All students row. At least one estimate here is a CDE weighted estimate; that describes how CDE combines years, not a year-over-year trend. A group absent from this table has no imported record shown here. Its absence alone does not establish its size or performance. CDE growth covers grades 4–8. SchoolScope does not use these CDE figures in its Scope Score.

Source notes. CDE reports scale-score points against the state’s expected score for matched students, never a percentage. Among SchoolScope's retained California elementary school records, the median English estimate is +2 and the middle half fall between −5 and +9 scale-score points — the spread is wide, so read the figure against it, not its sign alone. CDE's 2025 Dashboard weighted school estimate uses assessments from 2022–23, 2023–24, and 2024–25; adjacent reporting editions should not be read as independent annual changes. The CDE measure covers grades 4–8, and it is not part of the Scope Score.

AP pathway among CCI Prepared studentsCDE College/Career Indicator · CCI source year 2025 · all students · AP pathway rate 8% · AP-pathway numerator 5 · denominator 60 (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 60 of 133 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 2019.

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 $24,385,452 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.
