Colusa County California Schools Calendar

Four school districts operate wholly inside this Sacramento Valley county, and two more cross its borders, so no single calendar covers every student. Together the districts serve roughly 3,500 to 4,000 students in a farming region of rice, almonds, tomatoes and walnuts. Because agriculture, heat, tule fog and wildfire smoke shape the school year, the details below are specific to Colusa County rather than a generic California schedule.

School District Structure in Colusa County

Colusa is a county, not a parish or borough. Public education here is split among several independent districts, each with its own elected governing board and calendar.

• Colusa Unified School District serves the city of Colusa, the county seat, with Colusa High, George T. Egling Middle School, a primary school and an alternative high school and home program.
• Maxwell Unified School District serves Maxwell with an elementary, a middle school and Maxwell Senior High.
• Pierce Joint Unified School District serves Arbuckle, College City and Grand Island. Its campuses include Arbuckle Elementary, Grand Island Elementary, Lloyd G. Johnson Junior High, Pierce High and Arbuckle Alternative High.
• Williams Unified School District serves Williams, with Williams Primary, Williams Upper Elementary, Williams Junior/Senior High and Mid Valley High, a continuation school.
• Princeton Joint Unified School District and Stony Creek Joint Unified School District serve the Princeton area and the Stonyford foothills. Check which district draws your address, since boundaries cross into neighboring Glenn County.
• Colusa County Office of Education (CCOE), headquartered in Williams, is led by an elected County Superintendent of Schools. It runs S. William Abel Academy, a county community school, along with adult education and special education services. CCOE does not set the calendar for the unified districts.

Each district’s governing body is a Board of Trustees (or Governing Board), which adopts the calendar at a public meeting. Meetings are generally monthly, and agendas are posted ahead of time on district websites. This is a small, rural county, so families often have one or two schools per community and bus routes can be long.

Academic Calendar Structure

Colusa County districts typically start in early to mid-August and end in late May or early June. Exact start and end dates change each year and differ by district, so I have not listed specific dates. Calendars are generally adopted in the spring for the following school year.

• Semesters: Most schools use two semesters, with the first ending in December or January. High schools generally issue semester grades, and elementary schools may report by trimester or quarter.
• Instructional days: California requires 180 instructional days per year and minimum annual instructional minutes that vary by grade level. Districts that fall short can lose funding, so they build in some flexibility.
• School day times: Elementary schools usually start around 8:00 a.m. and finish in the early afternoon, with middle and high school days running later. Times vary by campus and by bus route, so check your school’s bell schedule.

Harvest-season staffing and seasonal family work influence attendance in the fall, and many families rely on district calendars to plan around it.

School Holidays and Breaks

Each board sets its own schedule, but typical observances include:

• Labor Day in early September
• Veterans Day (November 11) and a Thanksgiving break of several days
• Winter break of roughly two weeks around Christmas and New Year’s Day
• Martin Luther King Jr. Day in January
• Presidents’ Day, sometimes extended into a long weekend
• Spring break, usually one week in late March or April
• Memorial Day in late May

Some districts also observe Cesar Chavez Day or a mid-semester break. Dates shift annually, and districts do not always align with each other, so confirm with the district website before planning travel.

Families comparing foothill and valley counties may want to look at the Calaveras County schools calendar and the Colusa County schools calendar. Both are largely rural, with several independent districts, but they differ in geography and local conditions, so confirm dates with the specific district you use.

How to Find the Official Calendar

Because several districts operate here, start with the website of the district that serves your child’s school. Look under “District,” “Parents” or “Community” for the adopted PDF. Calendars are usually approved at a spring board meeting, and agendas are posted beforehand. Individual schools may post supplemental calendars for sports, events and activities. If you are unsure which district serves your address, CCOE can help, and your child’s school office can confirm.

Early Release Days, Teacher Workdays and Professional Development

Teachers typically report a few days before students in August for planning and training. During the year, districts may schedule staff development days when students are out and early release days so teachers can collaborate. California sets some required staff training topics, which districts fit into these days. Families are usually notified through the school calendar, text or email alerts and social media. Many Colusa County families speak Spanish at home, and districts often provide notices in both English and Spanish.

Emergency Closures and Weather Days

Closures in Colusa County are driven by conditions specific to the valley and foothills:

• Wildfire smoke and fire: Smoke can drift into the valley from fires in the Coast Range and Mendocino National Forest, and the Stonyford area has been affected by large fires.
• Heat: Late-summer heat can lead to schedule changes or modified outdoor activity.
• Tule fog: Dense winter fog can delay buses, particularly on rural roads.
• Storms and flooding: Heavy winter rain can affect roads and some rural attendance areas.
• Power outages: Planned or emergency shutoffs can close campuses.

The district superintendent makes the call, usually after consulting transportation staff, local agencies and weather or air-quality information. Families are notified by automated phone, text and email systems, district websites and social media. Local outlets such as the Colusa Sun-Herald and Sacramento and Chico television stations may also carry news, but confirm with your own district. California does not automatically require makeup days for every closure. Districts meet the 180-day rule through calendar flexibility, added days or state waivers in emergencies.

Graduation and End-of-Year Schedule

High schools hold final exams in the last weeks of spring. Graduation for Colusa, Maxwell, Pierce and Williams high schools generally takes place in late May or early June, often at the school’s own stadium or gym. Elementary and middle schools hold promotion ceremonies near the last day. Report cards are issued at term ends, and most districts offer an online parent portal for grades.

Back-to-School and Registration

Re-enrollment for returning students typically opens in spring, and new student registration continues through summer. Families commonly need:

• Proof of residency, such as a utility bill or lease
• Immunization records
• A birth certificate or other proof of age
• Prior school records, if transferring

Registration is handled at the district office, the school site or online, depending on the district. Supply lists are usually posted on school websites in late summer, and many schools hold orientation or meet-the-teacher nights before the first day.

Special Programs and Calendar Implications

S. William Abel Academy and the continuation schools, such as Mid Valley High in Williams, Arbuckle Alternative High and Colusa’s alternative high school, may use different bell times or calendars. Colusa also has a home-based alternative program. Dual enrollment for high school students generally follows the calendar of the college involved, which can differ from the K-12 schedule. Preschool and early childhood programs often have separate calendars, and some districts offer independent study options. Ask each program directly.

Athletics and Extracurricular Context

High school sports are governed by the California Interscholastic Federation (CIF), and Colusa County schools compete in the CIF Northern Section. Colusa, Pierce, Maxwell and Williams high schools play in various Northern Section leagues, so schedules vary by school. Athletic calendars are separate from the academic calendar, and practices and games may fall near finals or breaks.

State Requirements and California Law

The California Department of Education sets the 180-day minimum and annual instructional minutes by grade, and local boards design calendars within those limits. The state also controls waivers for emergency closures and sets some required staff training. Within those rules, each Colusa County board has latitude over start dates, breaks and early release days.
