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

Stage 1 of 2

The elementary years

The elementary schools average 69.4/100 — 30.6 points above the state average, with 6 of 6 in the Strong band.

0100
Strong Solid Developing Needs Support district avg state avg

6 elementary schools span 24 points around an average of 69.4.

The strength

Alta Vista Elementary (80/100) holds the Strong band — 60.1% of its students exceed the state standard, against a level average of 53.6%. 1 school classifies as Strong All-Around — no weak dimension we measure.

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 2

The middle years

One school defines the top: Union Middle sits 29 points clear of the field — the other 1 middle schools are a different conversation.

2 middle schools span 29 points around an average of 72.7.

The strength

Union Middle (87/100) holds the Strong band — 61.2% of its students exceed the state standard, against a level average of 51.1%.

The catch

29 points separate the top and bottom middle 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

Compare schools at your child’s level before deciding on an address. The strongest attendance-zone candidate is Alta Vista Elementary at 80/100 — 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.

The strongest-scoring run through the district:

Alta Vista Elementary 98th percentile · StrongScope Score 80/100Union Middle 99th percentile · StrongScope Score 87/100

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 Union Elementary?
This SchoolScope directory lists 8 public schools in Union Elementary 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 Union Elementary?
Among comprehensive public schools listed here, the highest Scope Score at each primary reporting level is: Elementary: Alta Vista Elementary (80/100). Middle: Union Middle (87/100). 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 Union Elementary 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.
