Direct AnswerThe Santa Clarita Valley runs a two-layer school system: the William S. Hart Union High School District serves grades 7–12 valley-wide (high schools include Valencia, West Ranch, Saugus, Hart, Canyon, and Golden Valley), while elementary grades are served by separate districts — Newhall, Saugus Union, Castaic Union, and Sulphur Springs Union. Which high school a home feeds is one of the strongest pricing variables in SCV: West Ranch and Valencia zones carry premiums over the valley median (~$850,000, June 2026).
Quick AnswerThe William S. Hart Union High School District serves grades 7–12 across the entire Santa Clarita Valley — seven comprehensive high schools layered over four separate elementary districts. The high-school zone a home feeds (West Ranch and Valencia carry the premiums) is one of the strongest pricing variables in SCV.

Two layers, not one district

SCV school shopping confuses buyers because no single district covers K-12. Elementary assignment comes from one of four K-6 districts (Newhall, Saugus Union, Castaic Union, Sulphur Springs Union); junior high and high school come from the Hart District. A Valencia address might pair Newhall District elementary with Valencia High; a Saugus address pairs Saugus Union elementary with Saugus High. Always check both layers.

How zone strategy plays out

Cross-shopping West Ranch vs Valencia vs Saugus zones is the most common SCV buyer conversation. The honest math: the same floor plan can differ $75K–$150K across high-school zones. If schools drive your move, set the zone first and the village second — Brian maps every SCV search by Hart District boundary before the first showing.

Frequently asked questions

Which SCV high school zone is most expensive?

Use the Hart District's boundary lookup plus the relevant elementary district's locator, then confirm with the schools. Boundaries shift with enrollment.
