Elementary schools are scored on their own scale — never ranked against other levels.

The elementary years

41 points separate Sonoma Mountain Elementary (66) from Miwok Valley Elementary Charter (25) — at this level, which school matters more than which district.

Strong Solid Developing Needs Support district avg state avg

41 points separate the strongest and weakest of these 6 elementary schools — the average hides more than it tells.

The strength

Sonoma Mountain Elementary (66/100) holds the Strong band — 50.7% of its students exceed the state standard, against a level average of 25.3%.

The catch

41 points separate the top and bottom elementary schools — the district average won't predict the school in front of you.

What it means for your family

If you're choosing a neighborhood

The 41-point spread means the district average is nearly meaningless for an address decision — the zoned elementary school is the whole decision. The strongest attendance-zone candidate is La Tercera Elementary at 38/100 — confirm the exact boundary with the district before the house.

If you already live here

5 of the 6 ranked schools are charters — enrollment paths that don't depend on your address. If your zoned school sits low in the appendix below, those lotteries and applications are the levers worth the paperwork.

If your kid is enrolled now

A band is a position, not a prophecy — 1 campus here ranks as On the Rise, its returning cohorts gaining more than most schools statewide. Ask your school two questions: what happens for a kid who arrives behind, and what the classroom looks like for one who arrives ahead.

The strongest-scoring campus:

Sonoma Mountain Elementary 91st percentile · StrongScope Score 66/100

The top scorer district-wide — confirm 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.

Which schools have the highest scores in Old Adobe Union?

Among comprehensive public schools listed here, the highest Scope Score at each primary reporting level is: Elementary: Sonoma Mountain Elementary (66/100).

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 Old Adobe Union 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.
