What Elementary and Middle Schools Serve the Mill Creek Area and Are They Part of the Everett or Mukilteo School District

Mill Creek is served by two separate school districts: Mukilteo School District and Everett School District. This split is not unusual for Snohomish County, where city incorporation boundaries and school district boundaries were drawn at different times and for different purposes. The result is that two homes on the same block can sometimes feed into different districts, and two homes that look identical in listing photos can have entirely different school assignments.

How the District Boundary Runs Through the City

The general dividing line runs roughly along Bothell-Everett Highway (Highway 527) and 35th Avenue SE, though the boundary has irregular segments that jog around specific subdivisions. Homes in the western and central portions of Mill Creek, including most of the neighborhoods surrounding the Mill Creek Town Center, tend to fall within Mukilteo School District. Homes in the eastern and northeastern portions of the city, particularly those closer to the Everett city limits, are more commonly assigned to Everett School District.

These are generalizations, not guarantees. The boundary has enough irregular segments that you cannot rely on a neighborhood name or a ZIP code to determine your district. Mill Creek's 98012 ZIP code, for example, includes addresses in both Mukilteo and Everett school districts. The only reliable method is to run the specific property address through each district's official address lookup tool, which both districts provide on their websites.

Why Your Street Address Is the Only Thing That Matters

Real estate listings on the MLS and on consumer portals do not always display the school assignment correctly. Some listings populate the school field automatically from a ZIP code or a neighborhood polygon, both of which can be wrong for edge-of-boundary addresses. If school assignment matters to your decision, treat any school name you see on a listing as a starting point for your own verification, not a confirmed fact.

This is especially relevant in Mill Creek because the city has grown significantly since the 1990s. Newer subdivisions built in the 2000s and 2010s along the eastern edges of the city were annexed into Mill Creek after the original district boundaries were established, and their school assignments sometimes surprise buyers who assumed the entire city fed into one district.

2. Elementary and Middle Schools in the Mukilteo School District Serving Mill Creek

The Mukilteo School District serves the majority of Mill Creek's residential neighborhoods. The district is headquartered in Everett but draws its name from the city of Mukilteo to the west. It operates dozens of schools across a large geographic footprint that includes Mukilteo, Lynnwood, Edmonds, and a substantial portion of Mill Creek.

Elementary Schools on the Mukilteo Side

Several elementary schools within or directly adjacent to Mill Creek serve Mukilteo-assigned addresses. Serene Lake Elementary is located inside Mill Creek's city limits on 35th Avenue SE and serves a wide swath of central Mill Creek. Fairmount Elementary, also within the city, serves neighborhoods in the northwestern quadrant. Discovery Elementary sits near the Mill Creek boundary and draws students from both Mill Creek and adjacent unincorporated areas. Olivia Park Elementary serves portions of Mill Creek closer to the Lynnwood and Mountlake Terrace edges of the district.

Elementary attendance boundaries within Mukilteo School District are redrawn periodically as enrollment shifts. The district last completed a boundary adjustment process in 2023, which moved some Mill Creek addresses from one elementary school to another. If you are looking at a home that was last sold several years ago, the elementary school listed on older documents may no longer be the assigned school. Always verify with the district directly.

Middle Schools on the Mukilteo Side

Middle school assignments in Mukilteo School District for Mill Creek addresses generally feed into Harbour Pointe Middle School or Explorer Middle School. Harbour Pointe Middle School is located in Mukilteo itself, roughly 10 to 12 miles from central Mill Creek via I-5 and Highway 525. Explorer Middle School is in Everett, closer to the northern portions of the district. Which middle school a student attends depends on which elementary school they came from, so the path is elementary assignment first, then middle school assignment follows from there.

Kamiak High School in Mukilteo and Mariner High School in Everett are the two high schools that most Mukilteo-assigned Mill Creek students feed into, depending on their middle school pathway. While this article focuses on elementary and middle schools, it is worth knowing the full pipeline so you can ask the district the right questions when you call to confirm your address assignment.

3. Elementary and Middle Schools in the Everett School District Serving Mill Creek

Everett School District serves the eastern portion of Mill Creek, where the city's newer subdivisions blend toward the Everett city boundary. The district is one of the larger districts in Washington State by enrollment and operates schools across Everett and into the surrounding unincorporated areas of Snohomish County.

Elementary Schools on the Everett Side

Mill Creek addresses assigned to Everett School District most commonly feed into Penny Creek Elementary or Cathcart Elementary. Penny Creek Elementary is located within Mill Creek's city limits, on the eastern side of the city near the Penny Creek greenbelt trail system. Cathcart Elementary is just outside the city boundary in unincorporated Snohomish County but serves some Mill Creek addresses in the northeastern corner of the city. Silver Lake Elementary in Everett also serves a smaller number of Mill Creek addresses near the city's northeastern edge.

Everett School District's attendance zones are also subject to periodic revision. The district uses an online school finder tool at the Everett School District website where you can enter a street address and receive the assigned elementary, middle, and high school. This is the most reliable source for Everett-side addresses and takes less than two minutes to use.

Middle Schools on the Everett Side

Mill Creek students in Everett School District typically feed into Eisenhower Middle School or Voyager Middle School for grades 6 through 8. Eisenhower Middle School is located in Everett proper, approximately 5 to 7 miles from the eastern edge of Mill Creek depending on the specific address. Voyager Middle School is also in Everett and serves a portion of the district's southwestern attendance zones, which include some Mill Creek neighborhoods.

The high school destination for most Everett-assigned Mill Creek students is Henry M. Jackson High School, which is located within Mill Creek's city limits on 171st Street SE. Jackson High is one of the larger high schools in Snohomish County and draws from both Everett School District and, for open enrollment purposes, students from surrounding areas. Its location inside Mill Creek makes it a visible part of the community regardless of which district a family is assigned to.

4. How to Confirm Which District and School Serves a Specific Mill Creek Address

The only way to know for certain which elementary and middle schools serve a Mill Creek address is to run that address through the official district tools. Neither a ZIP code, a neighborhood name, nor a listing description is sufficient. Both Mukilteo School District and Everett School District publish address lookup tools on their official websites, and both are updated when boundary changes take effect.

Use the Official District Locator Tools

To confirm a Mukilteo-side address, visit the Mukilteo School District website at mukilteoschools.org and use the school finder feature under the enrollment section. For an Everett-side address, go to everettsd.org and use the address lookup tool in the enrollment or schools section. Both tools return the assigned elementary, middle, and high school for any address within the district. If an address does not return a result in one district's tool, try the other district's tool, as that will tell you which side of the boundary the property sits on.

You can also call each district's enrollment office directly. Mukilteo School District's enrollment office can be reached at their main district number, and Everett School District has a dedicated enrollment line. Staff can confirm the assigned school for any address and can also tell you whether the property is close enough to a boundary that a future redistricting could affect the assignment.

What to Ask During a Home Search

When you are actively touring homes in Mill Creek, there are a few specific questions worth asking before you fall in love with a property. First, ask which school district serves the address, not which neighborhood it is in. Second, ask for the specific elementary and middle school assignment, not just the district name. Third, if the home is within a few blocks of a major road like 35th Avenue SE or Bothell-Everett Highway, ask whether the address has ever been subject to a boundary review.

If you are working with Agnes Austria of Pellego during your Mill Creek home search, she can help you identify which district a specific listing falls in and flag addresses that sit near the boundary line. Understanding the school assignment before you write an offer is much easier than discovering a mismatch after you are under contract.

5. Researching School Information on Your Own Terms

Once you know which schools serve a specific Mill Creek address, you will likely want to research those schools for yourself. The programs, services, and priorities that matter most vary from one family to the next. The most reliable approach is to go directly to official data sources and then supplement that with your own visits and conversations with current school community members.

Official State and District Sources

The Washington State Office of Superintendent of Public Instruction (OSPI) publishes annual report cards for every public school in the state at reportcard.ospi.k12.wa.us. These report cards include state assessment results, graduation rates, enrollment demographics, teacher qualification data, and chronic absenteeism rates. The data is reported at the individual school level, so you can look up Serene Lake Elementary, Penny Creek Elementary, or any other Mill Creek-area school directly. The OSPI report card is the most authoritative source for Washington school data because it comes from the agency that collects and audits the numbers.

Both Mukilteo School District and Everett School District also publish their own annual reports and strategic plans on their websites. These documents describe each district's goals, programs, and performance trends over time. They are useful for understanding the district's direction and priorities beyond what a single year of test scores can show.

Third-Party Data Sites and What They Actually Show

Third-party sites aggregate publicly available school data and present it in formats that are easier to scan than government report cards. Sites like GreatSchools compile state test scores, student-to-teacher ratios, and parent reviews for schools serving the Mill Creek area. These sites can be a useful starting point for finding which schools exist and what state data says about them, but they are a supplement to official sources, not a replacement.

Ratings on third-party sites are typically derived from a narrow set of metrics, most often standardized test proficiency rates. Those metrics do not capture program variety, extracurricular offerings, special education services, dual-language programs, or the day-to-day experience of students and teachers. Use the ratings as a way to locate the raw data, then go read the raw data yourself at OSPI before drawing conclusions.

Visiting the school in person, attending a school tour if one is offered, and speaking with parents in the Mill Creek community are all steps that no website can replicate. Mill Creek has an active community presence through its parks, the Town Center, and neighborhood associations, and local parents are generally willing to share their firsthand experiences with the schools their children attend. That kind of on-the-ground insight is worth more than any numerical rating.
