Trinity County California Schools Calendar

About 1,500 students attend public schools in Trinity County, one of California’s most sparsely populated counties, spread across a handful of small districts in the Trinity Alps, the Hayfork Valley, and the remote southern end of the county near Mad River. Mountain roads, heavy winter weather, and wildfire seasons shape the school year here more than in most California counties, and each district’s board sets its own calendar. Families in Weaverville, Hayfork, Lewiston, Junction City, and Mad River should confirm dates with their own district.

School District Structure in Trinity County

Trinity County is served by a small number of unified and elementary districts, with no city school systems. Trinity Alps Unified School District serves Weaverville and surrounding communities from kindergarten through twelfth grade. Mountain Valley Unified School District serves Hayfork and the Hyampom area. Southern Trinity Joint Unified School District serves the Mad River and Zenia area in the county’s south. Several small, single-campus elementary districts also operate, including Douglas City, Junction City, Burnt Ranch, and Lewiston, and their students may continue to high school in a neighboring district.

Each district is governed by a locally elected board, titled Board of Trustees or Board of Education depending on the district, and boards usually meet monthly with agendas posted ahead of time. The Trinity County Office of Education in Weaverville is led by an elected County Superintendent of Schools. It does not set district calendars, but it reviews budgets, runs county-operated programs, and provides training and administrative support that very small districts could not afford on their own.

Trinity County is entirely rural. Weaverville, the county seat, is the largest community, and others are separated by winding mountain highways such as Highway 299 and Highway 3. Long bus routes, tiny enrollments, and difficult winter travel all limit how much flexibility districts have when building a calendar.

For families comparing nearby counties, the Trinity County schools calendar resources from the county office of education link to each local district, and the Tehama County schools calendar guide shows how a neighboring valley county to the east organizes its own, much larger group of districts.

Academic Calendar Structure

Most Trinity County districts open in mid-August and close in late May or early June. Boards typically adopt the next year’s calendar in the spring, often after discussion with local teachers’ associations. Since the 2026-27 school year is already underway, each district’s current calendar has been posted and can be confirmed now.

Most districts use two semesters, with the fall term ending in December or early January and the spring term continuing through the end of the year. Elementary report cards are often issued by trimester, while the high schools use semester grades with progress reports in between. Because of the county’s size, some small schools may blend grade levels in a single classroom, which affects how reporting is organized.

California requires at least 175 instructional days, and most districts schedule close to 180. State law also sets minimum instructional minutes: 36,000 for kindergarten, 50,400 for grades one through three, 54,000 for grades four through eight, and 64,800 for grades nine through twelve. Districts that fall short can lose state funding. Small districts sometimes adjust daily schedules or calendar structure to meet the totals while managing long bus rides and winter conditions, so ask your district whether it uses any alternative weekly schedule.

Bell schedules vary by campus. Elementary schools commonly begin between 8:00 and 8:30 a.m. California’s start-time law covers most middle and high schools but exempts rural districts, which includes Trinity County, so start times follow local needs and bus logistics. Confirm your school’s schedule with the campus office.

School Holidays and Breaks

Trinity County districts generally observe the following, though dates and the number of days off vary:

• Labor Day, the first Monday of September
• Veterans Day, November 11 or the nearest weekday
• Thanksgiving Break, usually Wednesday through Friday, sometimes the full week
• Winter Break, typically about two weeks around Christmas and New Year’s Day
• Martin Luther King Jr. Day, the third Monday of January
• Presidents’ Day, with some districts closing for the full week
• Spring Break, often one week in late March or April
• Memorial Day, the last Monday of May

A fall break is not standard in the county, though a district may add a short pause. Exact dates change every year, so use your district’s adopted calendar rather than a neighboring district’s.

How to Find the Official Trinity County School Calendar

There is no single countywide calendar, so start with your district’s website. Trinity Alps Unified, Mountain Valley Unified, Southern Trinity Joint Unified, and the small elementary districts each post adopted calendars, usually as PDFs under sections labeled “District,” “Parents,” or “Community.” Because some small districts have simple websites, the front office or the Trinity County Office of Education can help if you cannot find a calendar online.

Boards typically adopt next year’s calendar at a spring meeting, with public agendas and minutes. Individual schools may publish supplemental calendars for back-to-school nights, parent conferences, testing, assemblies, and athletics, often through the school’s page, social media, or a parent communication app.

Early Release Days, Teacher Workdays, and Professional Development

Teachers generally return a few days before students in August for classroom preparation and training. During the year, districts schedule professional development days when students stay home, along with early release or minimum days. Small districts sometimes cluster these days to allow staff to travel to training in Redding or Eureka, which can be a long drive from Trinity County.

Districts notify families through websites, automated calls, texts, social media, and parent apps. Check the calendar at the start of each semester, especially if you commute to jobs outside the county. California requires staff development days through the Education Code and bargaining agreements, and districts often use them for curriculum, safety, and state-mandated training.

Emergency Closures and Weather Days

Trinity County has real winter weather. Snow and ice on mountain roads can close or delay schools, particularly at higher elevations around Weaverville, Trinity Center, and along Highway 3 toward Hayfork. Superintendents make closure and delay decisions, usually after checking road conditions early in the morning, often with input from bus drivers and Caltrans reports, and decisions typically focus on whether buses can run safely on the district’s longest and steepest routes.

Wildfire is the other major disruption. The county has dealt with repeated large fires, including the 2021 Monument Fire, and smoke and road closures can affect school operations for days or weeks. In severe cases, districts may close schools, move to indoor-only activity, or adjust schedules.

California districts must still meet minimum instructional days and minutes, so closures may require makeup days or use of built-in margin, and districts can request a state waiver in qualifying emergencies.

Families are notified through automated calls, texts, emails, district websites, and social media. Local sources include the weekly Trinity Journal, along with regional stations in Redding and Chico such as KRCR and KHSL. Because cell coverage is limited in parts of the county, make sure the school has multiple ways to reach you and ask how the district handles families without reliable service.

Graduation and End-of-Year Schedule

High school final exams usually fall in the last week or two of the spring semester. Graduation ceremonies for Trinity High School in Weaverville, Hayfork High, and Southern Trinity High typically take place in late May or early June, and are often community events held in school gyms or on school grounds. With classes of modest size, ceremonies are usually well attended by the surrounding community.

Elementary and middle schools usually hold promotion ceremonies in the final week. Report cards are distributed in the last days of school or posted to the district’s student information portal. Because internet access can be limited in remote areas, families without reliable service can ask the school office for printed copies.

Back-to-School and Registration Information

Enrollment and re-enrollment generally open in the spring for the following year, and new-student registration continues through summer and the school year. Transitional kindergarten is now open to all four-year-olds in California, so families with younger children should ask their district about age cutoffs and available sites.

To register, families generally need:

• Proof of residency, such as a utility bill or lease
• The child’s birth certificate or other proof of age
• Immunization records, as required for school entry under California law
• Prior school records or transcripts, when transferring

Registration is handled through school offices or district enrollment processes. Because some families live far from town, ask whether you can start the process by phone or email. Supply lists are usually posted in July or early August, and many campuses hold back-to-school nights or meet-the-teacher events near the start of school.

Special Programs and Their Calendar Implications

With such small enrollments, Trinity County has few magnet or specialty programs, but some programs follow separate calendars. Dual enrollment and early college classes through regional community colleges follow the college calendar, which differs from the district’s. Alternative and continuation programs, including those coordinated through the Trinity County Office of Education, may use different start dates, shorter days, or independent study schedules. State and district preschool programs and transitional kindergarten may run on separate calendars from the K-12 schedule. Independent study and virtual options are especially valuable in a county with long travel distances. Year-round calendars are uncommon, so ask your district directly.

Athletics and Extracurricular Calendar Context

High school athletics in Trinity County are governed by the California Interscholastic Federation (CIF), and local schools compete in the CIF Northern Section. CIF and the section set season dates, eligibility rules, and playoff schedules, not school districts. Away games can involve very long drives across mountain highways, so schedules sometimes affect school days, early dismissals, and winter weather planning. Practices and games may overlap with breaks and finals, so athletes should check with coaches and athletic directors.

State-Level Calendar Requirements and How California Law Governs Trinity County

The California Department of Education oversees statewide requirements, and the State Board of Education sets policy. The Education Code establishes the 175-day minimum and the instructional minute requirements described above. Within those rules, districts keep local control over start dates, breaks, and bell times, which allows Trinity County districts to design calendars around winter road conditions, fire season, and long bus routes, subject to board approval and collective bargaining.
