Which School Districts Serve Santa Clarita and How to Research the Public Schools There

Santa Clarita is primarily served by two public school districts: the William S. Hart Union High School District for grades 9 through 12, and the Newhall School District for kindergarten through eighth grade in a large portion of the valley. A third district, Castaic Union School District, serves the Castaic area at the northern edge of the Santa Clarita Valley and covers its own K through 8 students before they feed into Hart for high school.

The structure matters because it is not a single unified district. Elementary and middle school students attend schools governed by their elementary district, while high school is handled separately by Hart. That means a home in Valencia could send younger children to a Newhall School District campus while older students attend a Hart district high school. Understanding both layers is important when you are evaluating a specific address.

William S. Hart Union High School District

The Hart district covers essentially all of the Santa Clarita Valley for high school students. Its campuses include Hart High School in Newhall, Canyon High School in Canyon Country, Golden Valley High School in Newhall, Saugus High School in Saugus, Valencia High School in Valencia, and West Ranch High School in Stevenson Ranch. The district also operates Bowman High School as a continuation campus and several charter and alternative programs. The Hart district office is located in Newhall, and its boundaries extend from Newhall and Stevenson Ranch in the west to Canyon Country in the east and up to Castaic in the north.

Each high school in the Hart district serves a defined attendance zone, and those zones do not perfectly mirror city neighborhood names. A street in northern Valencia, for example, may fall within the West Ranch attendance area rather than Valencia High. The only reliable way to confirm which high school serves a specific address is to use the Hart district's online boundary lookup tool or call the district's enrollment office directly.

Newhall School District

The Newhall School District is the largest elementary district in the valley, serving kindergarten through eighth grade across Valencia, Newhall, Saugus, and parts of Stevenson Ranch. The district operates roughly two dozen campuses, including elementary schools and a set of middle schools. Its administrative office is on Orchard Village Road in Newhall. Students who complete eighth grade in the Newhall district then transition to one of the Hart district high schools based on their home address.

Castaic Union School District

Castaic Union School District serves the Castaic community, which sits at the northern end of the Santa Clarita Valley near Castaic Lake. The district operates Castaic Elementary and Castaic Middle School, among other campuses. High school students from Castaic attend Castaic High School, which is part of the Hart Union district and opened in 2019 to serve the growing population in that corridor. If you are considering a home in the Castaic area, you will be working with Castaic Union for the lower grades and Hart for the upper grades.

2. How District Boundaries Work in Santa Clarita Neighborhoods

School boundaries in Santa Clarita do not follow a simple grid. Two homes on the same street can sometimes feed into different elementary schools, and a move of a few blocks can shift which high school campus a student attends. This is one of the most common surprises for buyers relocating from outside the valley, and it is worth verifying before you make an offer on any specific property.

Valencia and Stevenson Ranch

Valencia is one of the largest communities in Santa Clarita, with a mix of planned neighborhoods, gated communities, and newer construction along the McBean Parkway and Bouquet Canyon Road corridors. Homes here range from townhomes in the mid-$500,000s to single-family homes well above $1 million in communities like Valencia Summit. The elementary schools serving Valencia are part of the Newhall School District, and high school students typically attend Valencia High or West Ranch High depending on which part of Valencia the home sits in.

Stevenson Ranch, which sits just west of the I-5 near the Los Angeles County line, also falls within the Newhall School District for elementary and middle grades. West Ranch High School, located in Stevenson Ranch on Westridge Parkway, serves most of that community for high school. Homes in Stevenson Ranch tend to be single-family properties built in the 1990s and 2000s, generally priced from the mid-$700,000s into the low $1 million range. You can read more about that community in the Stevenson Ranch real estate market guide on this site.

Canyon Country and Saugus

Canyon Country and Saugus sit on the eastern side of the valley, along the Soledad Canyon Road and Bouquet Canyon Road corridors. These communities tend to have more affordable price points than Valencia, with single-family homes frequently listed in the $600,000 to $850,000 range as of September 2026, though prices vary considerably by street and condition. Elementary and middle school students here are served by the Newhall School District, and high school students typically attend Canyon High or Saugus High within the Hart district.

Newhall and Castaic

The Newhall community, one of the older parts of the Santa Clarita Valley, has a walkable downtown area along Market Street with restaurants, shops, and the Lyons Avenue corridor nearby. Homes here include older Craftsman-style properties, mid-century ranches, and newer infill construction, generally priced from the low $500,000s to the mid-$700,000s. The Newhall School District serves elementary and middle grades, and Hart High School is the local high school campus for much of this area.

Castaic is a growing community north of the main valley, popular with buyers who want newer construction and larger lots near Castaic Lake Regional Park. Homes in Castaic are often newer builds, with many properties constructed after 2010, and prices generally run from the high $600,000s into the $900,000s for larger homes. Castaic Union School District handles K through 8, and Castaic High School, a Hart district campus that opened in 2019, serves high school students.

3. How to Research Santa Clarita Public Schools Using Official Sources

The most reliable way to research public schools in Santa Clarita is to go directly to government and district sources rather than relying on third-party ratings alone. Third-party sites can be a useful starting point for finding campus names and enrollment numbers, but the underlying data comes from official sources that you can access yourself. Going to those sources directly lets you see the full picture rather than a simplified score.

California Department of Education Data

The California Department of Education publishes enrollment figures, demographic data, program offerings, and test score results for every public school in the state at cde.ca.gov. You can search by school name or district and pull detailed reports. The site also links to each district's Local Control and Accountability Plan, which is a public document that describes what the district is prioritizing, how it is spending its funding, and what goals it has set for students. Reading that document gives you a much more complete picture than any single number.

What the California School Dashboard Measures

The area is served by public schools that fall under the Santa Clarita Valley's school districts, as a plain fact of location.

For general information on local schools, the California Department of Education publishes district and school directory information by zip code. The district's own published materials are a starting point for locating which schools serve a given address.

How to Use the District Websites Directly

Each district in the Santa Clarita Valley maintains its own website with enrollment information, boundary maps, program listings, and contact details. The William S. Hart Union High School District is at hartdistrict.org. The Newhall School District is at newhallschooldistrict.net. The Castaic Union School District is at castaicusd.org. All three sites include boundary lookup tools or contact information for the enrollment office, and calling the enrollment office directly is the fastest way to confirm which school serves a specific home address.

4. Researching Local Schools

When you are researching public schools in Santa Clarita, it is worth looking at program offerings, class sizes, extracurricular activities, and how the school communicates with parents. These are things you can learn from the district website, from school open houses, and from talking to people in the neighborhood.

Enrollment and Program Offerings

The Newhall School District and the Hart district both offer a range of programs beyond standard coursework. The Hart district, for example, operates the Academy of the Canyons, a dual-enrollment program on the College of the Canyons campus in Valencia that allows high school students to earn college credits simultaneously. College of the Canyons itself sits on Valencia Boulevard and is a well-established two-year institution that also offers community education and workforce training programs.

Magnet and Specialized Programs

Several Hart district high schools offer specialized academies and magnet-style pathways in areas such as performing arts, engineering, health sciences, and business. These programs sometimes accept students from outside the standard attendance zone through an application process, so a student living in one attendance area may be able to access a specialized program at a different campus. The district's website lists current program offerings and application windows, and the enrollment office can explain the process.

Asking the Right Questions at Open Houses

When you tour a home in Santa Clarita, it is reasonable to ask the listing agent which elementary school, middle school, and high school serve that specific address. A good agent will know the answer or be able to find it quickly. However, always verify independently through the district website or enrollment office before making a decision based on school boundaries, because boundaries can change and listing information is not always updated in real time.

5. How School District Boundaries Affect Home Values in Santa Clarita

School district boundaries have a measurable effect on buyer demand in Santa Clarita, and that demand influences pricing. Certain attendance zones within the Hart district and the Newhall School District attract more buyer interest than others, which can push prices higher for homes that happen to fall within those boundaries. This is a real market dynamic, not just a perception, and it is one reason why verifying the exact district and school assignment for a specific address matters so much during your search.

Boundary Changes Over Time

Districts in Santa Clarita have adjusted their boundaries over the years as the valley has grown. The opening of Castaic High School in 2019 was a significant example: students who had previously been assigned to other Hart campuses were redistricted to the new school. Similar adjustments happen at the elementary level as new neighborhoods are built and enrollment shifts. If you are making a long-term decision based on a school assignment, it is worth asking the district whether any boundary review is planned in the near future.

Verifying the District Before You Make an Offer

The most reliable method is to take the specific address of the home you are considering and run it through the district's boundary lookup tool. Both the Newhall School District and the Hart Union district have these tools on their websites. If the tool is unclear, a quick call to the enrollment office will give you a definitive answer. Do this before removing contingencies, not after, because a school assignment that does not match your expectations is not something you can change after closing.

6. Private Schools and Charter Options in the Santa Clarita Valley

Beyond the two main public districts, Santa Clarita has a number of private and charter school options that buyers sometimes factor into their search. Charter schools authorized through the Hart district or the Newhall district operate under public funding but with more flexibility in curriculum and structure. These schools typically have their own enrollment processes and may have waitlists, so if a charter campus is part of your plan, reaching out to that school directly as early as possible is advisable.

Private schools in the valley include faith-based campuses and independent college-preparatory schools. These are not governed by the public district boundaries and accept students from across the valley and beyond. If you are considering a private school, the campus location and commute from your prospective home address are worth factoring in, since the Santa Clarita Valley spans a significant geographic area and a school in Newhall may be a 20-minute drive from a home in Castaic.

7. Practical Steps for Buyers Researching Schools in Santa Clarita

Researching public schools in Santa Clarita is straightforward when you use the right sources in the right order. Here is a practical sequence that works well for buyers and relocating households:

Start with the district websites. Go to hartdistrict.org, newhallschooldistrict.net, and castaicusd.org to understand the structure, see the campus list, and access boundary tools. This takes about 30 minutes and gives you a solid foundation.

Run the specific address through the boundary tool. Do this for every address you are seriously considering, not just the neighborhood in general. Boundaries can shift at the street level, and assumptions based on neighborhood names are often wrong.

Check the California School Dashboard. Once you know the specific campus names, look them up at caschooldashboard.org to see how each school is performing across the state's multiple indicators. Look at the full set of indicators, not just one.

Call the enrollment office to confirm. If there is any ambiguity in the boundary tool result, or if you want to ask about upcoming boundary reviews or program availability, a phone call to the district enrollment office is the most reliable step. Staff can confirm the assignment for a specific address and answer questions about the enrollment process.

Visit the campuses. Most schools in the Hart and Newhall districts hold open houses or back-to-school nights that are open to prospective families. Visiting in person gives you a sense of the physical campus, the programs on offer, and the school culture that no data source can replicate.
