Almost the entire Santa Clarita Valley feeds one high school district, William S. Hart Union (grades 7-12), valley-wide. Elementary is where it splits: Newhall, Saugus Union, Sulphur Springs Union, or Castaic Union, depending on the neighborhood. Acton and Agua Dulce are the exception, one unified TK-12 district. This page names the district for each city; it does not claim a specific school for a specific address, since attendance boundaries change and the district's own locator is the only source that's always current.

"Split" cities have more than one elementary district serving different parts of town. This table names the district; it never asserts which specific school an address feeds.
The cities that split between two elementary districts
Most of Valencia is Newhall School District or Saugus Union; a small northwest corner is Castaic Union. The majority of Canyon Country is Sulphur Springs Union; parts are Saugus Union. Mostly Newhall School District; northeastern parts fall in Sulphur Springs Union.
Why this page won't tell you "your school"
The only nationwide attendance-boundary dataset is years stale, and pinning a specific school to a specific address that later turns out wrong is both a bad outcome for a buyer and a real liability and fair-housing risk for any site that does it. What's reliable and current is the district itself and its own official locator, linked above for every district. Use the locator with the exact address before you write an offer on schools alone.
