Not every Snohomish County school district is bringing home a report card worth putting on the refrigerator.
The latest school district evaluations from Niche reveal some noticeable differences across the county, with several districts earning strong marks while others have considerably more room for improvement.
According to Niche’s 2027 Best School Districts in Snohomish County, the education research and review website evaluated 13 local districts using factors including academics, graduation rates, teacher quality and student and parent feedback.
Overall grades ranged from A− to D+, with some districts receiving particularly low marks in academics and administration.
Three districts — Darrington, Granite Falls and Sultan — received grades among the lowest awarded in the county. Marysville School District also earned a C, tying Sultan’s overall grade.
But there’s more to these report cards than a single letter.
Here’s a closer look at what the numbers reveal.
Sultan School District — Overall Niche Grade: C
Sultan School District might have earned a C overall, but its academic performance tells a somewhat different story.
The district, which serves approximately 2,139 students in Sultan and surrounding communities, received a C+ for academics and a B+ for diversity.
According to Niche’s district profile, 55% of students are proficient in reading, while 39% meet proficiency standards in math.
Its reported graduation rate stands at 82%, with a student-teacher ratio of 19 to 1.
Those figures aren’t exactly a clean sweep, but they’re notably stronger than some of the academic results reported for the other districts examined here.
Where Sultan’s evaluation takes a hit is administration, which received a D. Resources and facilities earned a C−, while teachers received a C.
The contrast illustrates why overall grades don’t always tell the whole story: Sultan performs better in some academic measures than its overall evaluation might suggest.
It’s also worth noting that Marysville School District received the same overall C grade, meaning the two districts are tied at that grade level.
Granite Falls School District — Overall Niche Grade: C−
Granite Falls School District finds itself near the bottom of Snohomish County’s grade distribution, earning an overall C− from Niche.
And some of its academic numbers help explain why.
The district serves approximately 2,355 students and maintains a student-teacher ratio of 18 to 1.
According to Niche’s Granite Falls profile, 40% of students meet reading proficiency standards, while just 27% demonstrate proficiency in math.
The district’s reported graduation rate is 62% — substantially lower than the rates listed for Sultan and Darrington.
Administration received a D−, one of the weakest individual grades among the districts examined.
Academics earned a C−, while teachers received a C.
Still, the district has some brighter spots. Niche awarded Granite Falls a B for diversity and a B− for sports.
Those grades offer a reminder that even districts struggling in certain areas may have strengths that aren’t immediately apparent from their overall evaluations.
Darrington School District — Overall Niche Grade: D+
Of the 13 Snohomish County school districts evaluated by Niche, Darrington received the lowest overall letter grade.
And the academic numbers present some challenges.
Serving approximately 464 students in the Darrington area, the district is considerably smaller than many of its Snohomish County counterparts.
According to Niche’s Darrington profile, 31% of students meet proficiency standards in reading, while 24% demonstrate proficiency in math.
Academics received a C−, as did college preparation. Teachers and administration each earned a C.
But here’s an interesting twist.
Despite its D+ overall grade, Darrington’s reported graduation rate stands at 85% — higher than the rates listed for both Sultan and Granite Falls.
The district also maintains a student-teacher ratio of 15 to 1, the lowest among the three districts examined.
Niche awarded Darrington a B for diversity and another B for food.
Those individual grades don’t erase the district’s academic challenges, but they do provide some perspective on an otherwise disappointing overall evaluation.
How Does Niche Grade School Districts?
A school district’s overall grade involves more than test scores.
According to Niche’s ranking methodology, its evaluations incorporate a variety of factors, including academic performance, graduation rates, college readiness, teacher quality and feedback from students and parents.
The website draws on federal education data, public records and user-submitted reviews to assess schools and districts across the country.
For its 2027 rankings, Niche removed SAT and ACT scores from its ranking calculations, reflecting changes in how standardized admissions tests are used.
Individual district profiles also provide grades for categories such as diversity, administration, athletics, extracurricular activities and resources.
Importantly, those category grades offer additional context and shouldn’t be interpreted as equally weighted components of the overall grade.
The reading and math proficiency figures cited in this article come from Washington’s 2024–25 statewide assessments, as reported by Niche.
What Do These Grades Actually Mean?
A C or D+ might not inspire much confidence at first glance, but evaluating a school district isn’t quite as simple as checking a report card.
Consider the differences among these three districts.
Darrington received the lowest overall grade, yet its reported graduation rate exceeds those of both Granite Falls and Sultan.
Sultan earned a C overall but posted stronger reading and math proficiency results than the other two districts.
And Granite Falls, despite receiving a C−, earned comparatively favorable marks for diversity and athletics.
The figures also reflect districts serving very different communities and student populations, making direct comparisons more complicated than they might initially appear.
For parents, Niche’s evaluations can provide a useful starting point when researching local schools.
But academic programs, individual school performance, student support services and personal experiences deserve consideration, too.
Because when it comes to education, the most important question isn’t necessarily which district has the highest letter grade.
It’s whether a school is giving its students the opportunities and support they need to succeed.
