Stage 1 of 2

The elementary years

One elementary school: Santa Clarita Valley International at 37/100 — the whole story at this level is one campus.

Strong Solid Developing Needs Support district avg state avg

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

The strength

1 of the 1 elementary schools with measurable cohort evidence meet the stronger cohort-gains threshold — aggregate cohort-change indices above the published threshold.

The catch

3 continuation/alternative schools not plotted — they rank within their own class, not on this statewide axis.

The strength

West Ranch High (81/100) holds the Strong band — 49.8% of its students exceed the state standard, against a level average of 27.4%.

The catch

68 points separate the top and bottom high 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. Every ranked elementary school here is a charter or magnet, so the application matters more than the address — see the next card.

If you already live here

3 of the 13 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 Growth Engine, its aggregate cohort-change indices above the published threshold. 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:

Santa Clarita Valley International 54th percentile · SolidScope Score 37/100West Ranch High 96th percentile · StrongScope Score 81/100

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 William S. Hart Union High?

This SchoolScope directory lists 13 public schools in William S. Hart Union High 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 William S. Hart Union High?

Among comprehensive public schools listed here, the highest Scope Score at each primary reporting level is: Elementary: Santa Clarita Valley International (37/100). High: West Ranch High (81/100). 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 William S. Hart Union High 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.
