For 2025–26, the state put Island High (Continuation) in extra targeted support (ATSI), because a student group has stayed behind: low-income students. This is its 4th year in a row.

Any absence or suspension percentage shown here is a SchoolScope model-adjusted scoring input, not a raw CDE-reported school rate. The State column averages these inputs across scored comprehensive California schools at this level.
From 2025–26 reporting, California calls Level 3 Proficient and Level 4 Advanced (formerly Standard Met and Standard Exceeded). “Proficient or Advanced” combines both levels in the 2025–26 results shown here. California's level descriptions.

Current 2025–26 grade results appear above. The 2015–2018 rows were checked against original CDE files; independent re-verification of other stored historical years remains incomplete. The 2015 and 2016 percentages are rounded to whole numbers in the source. “Students with scores” is the rate denominator for that grade, subject and year. A missing result is not zero or a matched cohort.

2025 Scope Score · CDE overall Prepared model · CCI 2025: 16/100. Earlier scores are shown under the legacy model. The score models differ, so their results do not form one trend.
| Measure | Source record |
|---|---|
| This school · CCI overall Prepared | CDE College/Career Indicator · CCI source year 2025 · student group ALL (all students) · all students in the current four-year graduation cohort, plus only Prepared fifth-year graduates from the prior cohort. Overall CCI Prepared rate 2.1% · numerator 1 students classified Prepared · denominator 47 CCI students. |

CDE's overall Prepared rate is this version's 20% high-school college-readiness score factor. The school rate is 1 of 47 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.
| Assessment year | Scope Score | Percentile | Rank | Comparison group |

| 2024 | 16/100 | 16 | #278 | California continuation high schools · 332 schools |
These are retrospective calculations using earlier test results and current school levels and comparison classes. Each year's rank and percentile use that year's measured school group. They do not form a trend across different score models.
The legacy high-school model uses 2024–25 graduation records. Its readiness input uses the 2025 AP pathway share among Prepared students when available; otherwise it uses 2024–25 A-G completion. A reported zero remains zero. These inputs do not describe graduation or readiness in the earlier assessment years. The newer 2026 model instead uses CDE's overall Prepared rate.
Historical ELPAC inputs are absent from these calculations. Missing factor weights are redistributed proportionally among available factors. Adjusted climate values are SchoolScope scoring inputs, distinct from the state’s reported rates.
CDE reported all-students (TA) school rates for 2025 and 2026; the change is 2026 minus 2025 in percentage points.

Each year names its school year end (2026 = 2025–26). “Students with scores” is the subject-specific rate denominator; ELA and Math counts must not be added. The 2015–2018 rows were checked against CDE’s original research files. The 2015 and 2016 files report whole percentages; later rows round to one decimal here. Older stored rows from other years still need independent original-file re-verification. A dash is unavailable, not zero. Before spring 2026, Advanced was reported as Exceeded and proficient or advanced as met or exceeded.
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.

These figures are not directly comparable: school ESSA attributed spending and NCES district current expense use different measures and populations. Their fiscal years are labeled above.
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.
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.
