Butte County California Schools Calendar

Fourteen school districts share responsibility for educating roughly 30,000 public school students in this northern Sacramento Valley county, so the first day of school, the length of winter break, and even the weeks off in spring can differ from one town to the next. Chico, Oroville, Paradise, and Gridley each run their own schedules, and the county has also had to plan around wildfire and flood emergencies that most California counties rarely face. This guide explains how those calendars are built and where to find the one that applies to your child.

School District Structure in Butte County

Butte County stretches from the flat farmland of the Sacramento Valley around Gridley, Biggs, and Durham up into the Sierra foothills near Paradise, Magalia, Bangor, and Feather Falls, with Oroville as the county seat and Chico as the largest city. Education is organized into independent districts, each with its own elected governing board, plus the Butte County Office of Education in Oroville, which supports the districts and runs countywide programs.

The largest is Chico Unified School District, which serves the Chico area and surrounding communities. Paradise Unified School District serves Paradise and the foothill ridge. Gridley Unified, Biggs Unified, and Durham Unified are unified districts that cover their communities from kindergarten through high school. The Oroville area is served by a split system: Oroville City Elementary, Thermalito Union Elementary, and Palermo Union Elementary teach the younger grades, while Oroville Union High School District serves high school students from those feeder districts. Smaller rural elementary districts include Bangor Union Elementary, Feather Falls Union Elementary, Golden Feather Union Elementary, Manzanita Elementary, and Pioneer Union Elementary.

This matters because a family in Oroville may have a child in an elementary district and another in the high school district, and each follows a separate calendar. Each board holds public meetings on a regular schedule and posts agendas on its district website. Butte County is a mix of urban and suburban areas around Chico, small agricultural towns in the valley, and rural mountain communities, and those differences affect bus routes, staffing, and how much flexibility each district has when designing its year.

Academic Calendar Structure

Most Butte County districts begin school in mid-August and finish in late May or early June, though start dates differ by district and by year. Boards generally adopt the next year’s calendar in the winter or spring, sometimes approving two years at once. Because the elementary and high school districts in the Oroville area adopt separate calendars, they often try to coordinate start dates and major breaks, but it is not guaranteed.

Students follow two semesters in most schools, with the fall semester ending near winter break or in January. Elementary schools commonly issue report cards by trimester or by semester, depending on the district, and middle and high schools use semesters with progress reports. Check your school’s grading calendar for exact dates.

California requires 180 instructional days and sets minimum instructional minutes by grade: 36,000 for kindergarten, 50,400 for grades 1 through 3, 54,000 for grades 4 through 8, and 64,800 for grades 9 through 12. Butte County districts design their calendars to meet those requirements. Bell schedules vary widely. Elementary schools generally begin in the early morning and end in mid-afternoon, and some high schools have adjusted start times in recent years. Rural districts may start slightly earlier to match long bus routes, so confirm times with your school.

School Holidays and Breaks

Butte County districts observe the standard California school holidays, though each board decides which days to include:

• Labor Day in early September
• Veterans Day in November
• Thanksgiving break, usually several days
• Winter break, typically about two weeks around Christmas and New Year’s Day
• Martin Luther King Jr. Day in January
• Presidents’ Day in February, sometimes with a longer winter break
• Spring break, usually one week in late March or April
• Memorial Day

Some districts also observe Cesar Chavez Day or Indigenous Peoples’ Day. Because Chico is home to California State University, Chico, and Butte College serves the county, some families also pay attention to the college calendars, but K-12 schools follow their own. Dates change each year, so rely on the adopted calendar rather than last year’s.

How to Find the Official Butte County School Calendar

There is no single countywide calendar, so find your district first. Each district publishes its board-adopted calendar on its own website, usually under sections for the district, parents, families, or calendar, often as a downloadable PDF. If you are unsure which district serves your address, contact the Butte County Office of Education in Oroville or call the district offices directly.

Individual schools post their own event calendars for back-to-school nights, concerts, sports, and fundraisers. If you have children in different districts, such as an elementary student in Thermalito and a high schooler in the Oroville Union High School District, keep both calendars handy, since days off may not match.

Families comparing how small foothill counties handle scheduling can look at the Amador County schools calendar, which has a single district, and then return to the Butte County schools calendar for the multi-district picture in the northern Sacramento Valley.

Early Release Days, Teacher Workdays, and Professional Development

Teachers in Butte County typically report a few days before students for planning and training. California allows districts to count up to three staff development days toward the 180-day requirement, and many Butte County districts schedule pupil-free days during the year for training and collaboration.

Districts also use early release or minimum days, often weekly or monthly, so teachers can plan together. These are listed on the calendar and announced through school newsletters, automated calls and texts, and parent apps. State-required staff training, including mandated reporter and safety topics, is usually completed during these workdays or online. With so many separate districts, the number and timing of these days can differ from one town to another.

Emergency Closures and Weather Days

Butte County has faced emergencies that shape how schools think about closures. Wildfire is the biggest concern. The 2018 Camp Fire devastated Paradise and nearby foothill communities and changed the school landscape there, and smoke from fires in the county or the region can lead to closures or indoor-only days across the valley. In 2017, concerns about the Oroville Dam spillway led to evacuations that affected schools. Summer heat, winter storms, flooding, and power shutoffs during high-wind events can also interrupt school.

Closure decisions are made by each district’s superintendent, working with local fire and emergency officials, road crews, and air quality data. California does not build weather makeup days into the calendar, and closures that drop a district below 180 days can affect funding, so districts generally try to stay open when conditions are safe and may seek relief from the state after major disasters.

Families are notified by the district’s automated call, text, and email system, the district website, and social media. Local stations including KHSL CBS 12 and KRCR ABC 7, along with local newspapers such as the Chico Enterprise-Record, the Oroville Mercury-Register, and the Paradise Post, carry closing news during major events. Keep your contact information current with your school office so alerts reach you quickly.

Graduation and End-of-Year Schedule

High school finals typically happen in the last week before winter break or in January and again in late May or early June. Seniors often finish earlier than underclassmen.

Graduation ceremonies at Butte County high schools, including those in Chico, Oroville, Paradise, Gridley, Biggs, and Durham, take place in late May or early June, usually at campus stadiums or gyms, with larger schools sometimes using larger venues. Elementary and middle schools often hold promotion or recognition events in the final week. Report cards are distributed at the end of each grading period, and families can view grades and attendance through the district’s online student portal. Your school office can help with login questions.

Back-to-School and Registration Information

Enrollment varies by district. Larger districts such as Chico Unified and Paradise Unified typically open registration in the spring for the following year and offer online options, while smaller rural districts may ask families to contact the school or district office directly. Kindergarten students generally must be five on or before September 1, and transitional kindergarten is available under state law for younger children.

Typical documents include:

• Proof of residency, such as a lease or utility bill
• Proof of the child’s age, such as a birth certificate
• Immunization records, which California requires for school entry
• Prior school records, if transferring

Supply lists are usually posted on school websites in the summer, and many schools host back-to-school nights or meet-the-teacher events in August or early in the year, which appear on the school calendar. Families who move within the county may need to enroll in a different district, so ask about interdistrict transfer options if you want your child to stay put.

Special Programs and Their Calendar Implications

Butte County has a range of programs that may follow different schedules. Chico Unified offers alternative and choice schools, and several districts run independent study or online options for families who want flexibility. The Butte County Office of Education operates special education and alternative education programs with their own calendars. High school students can take dual enrollment courses through Butte College, and those classes follow the college calendar rather than the high school’s. Preschool, transitional kindergarten, and state preschool programs may use different hours or start dates. Charter schools in the county, including those authorized by local districts, set their own calendars and may start earlier or end later. Confirm with the specific program if your child is enrolled outside a standard classroom.

Athletics and Extracurricular Calendar Context

High school sports in California are governed by the California Interscholastic Federation. Most Butte County schools compete in the CIF Northern Section, which sets season dates, eligibility, and playoffs. Athletic schedules are separate from the academic calendar but linked to it: fall football and volleyball begin soon after school opens, winter sports continue around holidays, and spring playoffs can extend into the final weeks of school. Practices may continue during some breaks, and exam weeks can limit scheduling. Each school’s athletics page lists current dates.

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

The California Department of Education and the State Board of Education set the framework for school calendars in Butte County. State law establishes the 180-day expectation, the minimum instructional minutes by grade, and the rules for staff development days and minimum days. Each local board then chooses start and end dates, break placement, and early release patterns within those limits and in consultation with the educators who work under negotiated agreements. In a county with this many districts, that means the same state rules produce a variety of local calendars.
