Costa Mesa High — Rating & test scores

The 2024–25 Scope Score, in the current-formula row below, uses the state’s college-or-career readiness measure, 2024–25. No verified earlier Scope Scores are available here.

Chronic absence and suspension are CDE’s all-students school rates for each year.

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. “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; here that is grades 7 and 8. SchoolScope does not use these CDE figures in its Scope Score.

Two reported school years only; no intervening-year result is implied. Source: CDE school-level chronic absenteeism by student group.

These source periods and populations differ: graduation uses an adjusted cohort, while A–G completion and college-going use separately reported groups. The rates are shown individually, without a shared performance tier.

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.

Source: UC admissions by source school. Dated fall first-year UC applicants, admitted students, and enrollees. Campus totals are not interchangeable with Universitywide; students can apply to several campuses. Universitywide is separately reported; never derive it by adding campus rows. Universitywide applicant and admit counts are unduplicated. 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; these records do not establish a school's effect or predict individual chances.

Authorization ≠ a section running this year — the Ledger records what the school may teach, not seat counts.

These counts aren’t part of the Scope Score. “Not reported” means the federal record has no value for that item; it isn’t a zero. Enrollment counts add the male and female students the survey reports.

263 students who finished high school, class of 2023 · state-reported college-going rate 83% · % column is computed by SchoolScope (count ÷ all who finished high school; CDE calls them completers), not a CDE-native rate · an unavailable or suppressed cell is marked as missing; a reported zero remains distinct · source: CDE 12-mo CGR, 2023 cohort (the newest published), National Student Clearinghouse match — a different, older vintage than the fall 2025 UC admissions rows above.
