Each level is scored on its own scale — elementary, middle, and high are never ranked against each other.

Stage 1 of 3

The elementary years

The elementary schools sit at the state line (37.1 vs 38.9) — the 18-point school-to-school spread is where the choice lives.

0100
Strong Solid Developing Needs Support district avg state avg

5 elementary schools span 18 points around an average of 37.1.

The strength

Willow Elementary is the strongest option at 47/100 — 34.3% of its students exceed the state standard.

The catch

What these numbers can't see: class sizes, arts, teacher turnover, how a hallway feels at 8 a.m. Strong scores are the start of the question, not the answer.

Stage 2 of 3

The middle years

One middle school: Oak Knoll Alternative at 26/100 — the whole story at this level is one campus.

0100

One dot, one school — there is no spread to read at this level.

The strength

Oak Knoll Alternative is the strongest option at 26/100 — 6.3% of its students exceed the state standard.

The catch

The level sits 12.3 points below the state line.

Stage 3 of 3

The high school years

The path ends on a single bet: Charter Oak High at 52, then a 34-point drop to the next of 2 high schools.

0100

34 points separate the strongest and weakest of these 2 high schools — the average hides more than it tells.

1 continuation/alternative school not plotted — it ranks within its own class, not on this statewide axis.

The strength

Charter Oak High is the strongest option at 52/100 — 17.9% of its students exceed the state standard.

The catch

39.4% of students are chronically absent (state: 23.1%) — chronic means missing 10% or more of the school year. Whatever the scores say, ask each school what it is doing about attendance.

What it means for your family

If you're choosing a neighborhood

Compare schools at your child’s level before deciding on an address. The strongest attendance-zone candidate is Willow Elementary at 47/100 — confirm the exact boundary with the district before the house.

If you already live here

No charters or magnets among the ranked schools here, so the main lever is an intra-district transfer — California districts run them on their own windows and criteria. If your zoned school sits low in the appendix below, ask the district office for this year's dates.

If your kid is enrolled now

A band is a position, not a prophecy — a school's number can move without your kid's experience moving with it. Ask your school two questions: what happens for a kid who arrives behind, and what the classroom looks like for one who arrives ahead.

Top scorers at each level — not necessarily one zoned sequence. Confirm feeder patterns and enrollment zones with the district, and visit before you decide.

What this page can't see: whether a campus feels safe and glad at 8 a.m. If a path above looks workable, the next step is a visit.

Frequently asked questions

How many schools are listed in Charter Oak Unified?
This SchoolScope directory lists 8 public schools in Charter Oak Unified with 2024–25 reporting records. This is directory coverage, not a complete campus inventory. Each school appears under its primary reporting level; a K–8 or K–12 campus may serve additional grades.
Which schools have the highest scores in Charter Oak Unified?
Among comprehensive public schools listed here, the highest Scope Score at each primary reporting level is: Elementary: Willow Elementary (47/100). Middle: Oak Knoll Alternative (26/100). High: Charter Oak High (52/100). These are separate level rankings, not a single cross-level league table. A score does not establish fit or enrollment eligibility. See the methodology.
Can I compare elementary, middle, and high schools directly?
Compare schools at the same level and within the same enrollment group. Scope Score formulas and available measures differ by level. The plots show comprehensive public schools separately for each level; individual profiles explain their comparison group.
Does living in Charter Oak Unified guarantee a particular school?
A district outline does not establish assignment to an individual school. Attendance boundaries, programs, permits, and available space can affect enrollment. Confirm the requirements directly with the district.
What does a SchoolScope pattern mean?
Archetypes summarize patterns in publicly reported academic and school-climate measures. They describe reported results, not a school’s quality or a child’s fit. Open the school profile for reporting years, missing measures, and questions to ask. Read how the patterns are defined.
Where do these results come from?
The underlying public data comes from the California Department of Education, including CAASPP reporting for 2024–25. Scope Scores and archetypes are SchoolScope calculations, not official CDE ratings. View CDE data and SchoolScope’s methodology and limitations.
