Direct AnswerThe SCV runs a two-layer, five-district system: the William S. Hart Union High School District serves grades 7–12 valley-wide (Valencia, West Ranch, Saugus, Hart, Canyon, Golden Valley, and Castaic high schools), layered over four elementary districts — Newhall School District (Newhall/Valencia south, including Stevenson Ranch), Saugus Union (Saugus/Valencia north), Sulphur Springs Union (Canyon Country east), and Castaic Union (Castaic, K-8). Every SCV address pairs one elementary district with the Hart District; the pairing — not just the high school — is what buyers should verify per address.

The two layers, mapped

How to verify any address

Two lookups, always: the elementary district's own boundary locator AND the Hart District's zone map — because the layers don't share boundaries, and a Saugus Union address can feed Valencia High while a Newhall SD address feeds West Ranch. Brian runs both checks on every SCV search; mislabeled listings are routine on village seams.

Frequently asked questions

How many school districts serve Santa Clarita?

Does Castaic have its own school district?

Castaic Union School District serves K-8; high schoolers attend Castaic High School, which is part of the Hart District. (There is no separate "Castaic" high-school district.)

Which elementary district is most sought-after?

Newhall School District (Stevenson Ranch/Valencia south) carries the strongest reputation premium; Saugus Union's top zones compete closely. Verify the specific school, not just the district.
