Mendocino County’s latest school district report cards range from A− to C−. But some districts toward the lower end still earn strong marks for teachers, diversity or college preparation. Apparently, even a report card needs a closer reading.
Niche’s 2027 county listing, its latest available edition, includes nine districts with overall grades. This article examines the lowest grades within that group—not every public district serving the county.
Two districts share the lowest grade, C−, while four receive C+. Because those four tie at the cutoff for a third selection, all six appear below. Within each tied group, districts are presented alphabetically.
Niche’s evaluation combines academic results with teachers, school resources, extracurricular opportunities and family feedback. These are overall letter grades, rather than numerical ranking positions, and test scores alone don’t determine them.
Anderson Valley Unified School District — Overall Niche Grade: C+, tied
For families in Boonville and the surrounding Anderson Valley, the school district is also a place where community investment takes tangible shape.
One example is the district’s announced $4.7 million track and field project, designed to bring an all-weather running track and a soccer and football field to its junior-senior high school. The plans include community access outside school hours.
Anderson Valley receives C+ in Niche’s current county listing. Separately, federal education records for 2024–25 show 382 students and approximately 15 students per full-time-equivalent teacher.
That makes this a small district with a substantial facilities investment to follow. The project doesn’t establish academic success, but it gives families something concrete to examine alongside the grade.
Fort Bragg Unified School District — Overall Niche Grade: C+, tied
Fort Bragg’s most striking contrast is between its overall C+ and its A− for college preparation.
Its 2027 Niche profile also awards B for teachers, while academics receive C+. The coastal district’s category grades offer a more varied picture than the overall letter suggests.
There are specific opportunities behind that college conversation. Fort Bragg High School’s partnership with Mendocino College lets students take college courses that also count toward their high school diploma.
The district says those dual-enrollment courses carry no tuition or fees, and it also offers Advanced Placement classes.
For students ready for that work, access matters. Families should ask which courses are available, who participates and what support helps students complete them.
Laytonville Unified School District — Overall Niche Grade: C+, tied
Small district, broader course options than some readers might expect.
Laytonville Unified receives C+ overall in Niche’s 2027 listing and A− for diversity. The California Department of Education reports 326 students for 2025–26, putting the district on a very different scale from larger county systems.
Its high school’s 2024 School Accountability Report Card describes seven career technical education pathways, alongside advanced classes including physics, chemistry and AP English.
Those offerings deserve a place in the discussion. The useful next question is how students in Laytonville and nearby communities move through those pathways—and whether they leave with skills, credits or qualifications that help after graduation.
Potter Valley Community Unified School District — Overall Niche Grade: C+, tied
Potter Valley’s educational offerings include a school farm, an orchard and a greenhouse. That is a little more specific than the usual promise of “hands-on learning.”
The rural district receives C+ overall, with B for teachers in Niche’s 2027 evaluations.
Its official website describes a student population of roughly 260, along with dual-enrollment college programs, FFA and free after-school programming for transitional kindergarten through eighth grade.
For a district this small, the range of activities is worth exploring. So is the practical question of access: which programs fit a student’s interests, schedule and academic needs?
The overall grade provides one reference point. The farm, college courses and student support services give families more specific things to investigate.
Round Valley Unified School District — Overall Niche Grade: C−, tied
Round Valley shares the lowest overall grade in Niche’s county listing, but its own improvement plan provides a more useful discussion than the letter alone.
The district, based in Covelo, had 447 students in federal 2024–25 records. It receives B for diversity in Niche’s 2027 evaluations.
Its 2025–26 accountability plan identifies reading intervention, credit recovery and college-preparatory course completion as areas of work. It also describes Native language and cultural coursework and dual enrollment with Mendocino College.
Those commitments give families specific questions to bring to the district: Are students receiving the planned help, and what progress is it producing? That is where a broad evaluation becomes a useful local conversation.
Willits Unified School District — Overall Niche Grade: C−, tied
Willits has one of the most uneven report cards in the group.
Its 2027 Niche profile gives academics C− and administration D+, alongside a B for college preparation. That combination points families toward separate questions about academic outcomes, school leadership and opportunities after high school.
The district’s website describes approximately 1,530 students across six schools serving the Willits community.
The administration grade is unfavorable and worth reporting plainly. It is still Niche’s assessment, rather than evidence by itself of a specific management failure.
Families considering the district can use it to guide questions about communication, student support and how concerns are resolved.
Willits and Round Valley remain tied at C− overall; neither sits below the other on that measure.
Read the grade. Then visit the school.
These evaluations compare districts with different enrollment sizes, communities and student needs.
Receiving one of the lowest grades in this county listing does not automatically establish poor statewide performance—or describe what every student experiences.
For families, the best follow-up is specific: examine individual school outcomes, ask about programs and support, and talk with the people who use them.
A letter can start the conversation. It shouldn’t get the last word.
