Boise County Idaho Schools Calendar

Boise County, Idaho is served by a single small school district based in Idaho City, and its roughly 1,000 students are spread across a mountainous county of old mining towns and forested basins. What sets the calendar apart is a rural district that serves very different communities, from Idaho City and Garden Valley to Horseshoe Bend and Lowman, all under one locally elected board.

School District Structure in Boise County

Boise County sits in the mountains of southwestern Idaho, northeast of the Treasure Valley, with Idaho City as the county seat. It is a different place from the city of Boise, which lies in neighboring Ada County, and the two should not be confused. Public education here is handled by two districts, each governed by a locally elected Board of Trustees and led by a superintendent.

• Basin School District No. 72, based in Idaho City, serves Idaho City, Placerville, Centerville, and the Boise Basin, with Basin Elementary School and Basin High School.
• Garden Valley School District No. 71, based in Garden Valley, serves Garden Valley, Crouch, and the South Fork of the Payette River corridor, with Garden Valley School.
• Horseshoe Bend School District No. 73, based in Horseshoe Bend, serves Horseshoe Bend and the lower Payette River area, including parts of the county’s western edge.

Each board meets on a regular monthly schedule, with agendas and minutes available through the district offices and websites. Because the districts are independent, start dates, break weeks, and last days of school can differ even though the communities are only a short drive apart on State Highways 21, 55, and 17.

Families who move around Idaho often compare how different parts of the state schedule the year. The Blaine county schools calendar shows how a single resort-valley district builds one shared schedule around ski season and seasonal employment, while the Boise county schools calendar shows how several small mountain districts each set their own start dates, breaks, and bus plans around heavy winter weather and long, winding roads. Reading both explains why a school year in Hailey may not line up with one in Idaho City or Garden Valley.

Boise County is rural and forested, with very small communities, a low population density, and long travel distances. Many residents commute to the Treasure Valley for work, which shapes bus routes, early dismissal needs, and how much flexibility each district has.

Academic Calendar Structure

Boise County districts generally begin the school year in mid to late August, with teachers reporting a few days earlier, and finish in late May or early June. Exact dates change each year and vary by district, so use the calendar adopted by the district that serves your address. Boards usually approve the next year’s calendar in the winter or spring.

Schools typically divide the year into two semesters, with the first ending around winter break. Elementary grades often report progress in trimesters or quarters, while secondary students use semester grades with quarterly checkpoints. Idaho sets minimum instructional time in hours rather than days, and districts build calendars that meet or exceed those hours. Some rural Idaho districts adjust the length of the school week, so confirm the weekly schedule with your district.

School day hours are set locally. Schools in Idaho City, Garden Valley, and Horseshoe Bend run on different bell schedules, and times can shift to fit long bus routes. Check your school’s website or office for current times.

School Holidays and Breaks

Boise County districts observe a familiar set of breaks, with timing that varies by year and district:

• Labor Day in early September
• Thanksgiving break around Thanksgiving Day
• Winter break of about two weeks around Christmas and New Year’s Day
• Martin Luther King Jr. Day, observed in Idaho as Martin Luther King Jr.-Idaho Human Rights Day
• Presidents’ Day in February
• Spring break, typically in late March or early April
• Memorial Day in late May

Districts may add a fall break or long weekends around hunting season or local events. These dates shift annually, so confirm them against the adopted calendar.

How to Find the Official Boise County School Calendar

There is no single Boise County calendar, so start with the district that serves your address. Basin, Garden Valley, and Horseshoe Bend School Districts each post their calendars on their district websites, usually under sections labeled “District,” “Parents,” or “Community,” often as a PDF. The district offices can also provide a copy.

Boards of Trustees typically adopt the next year’s calendar at a public meeting in the winter or spring, and the minutes record the vote. Individual schools also keep supplemental calendars for athletics, concerts, testing windows, and open houses, so check your child’s school page as well.

Early Release Days, Teacher Workdays, and Professional Development

Teachers in Boise County report before students for planning and training, and several days during the year are set aside for professional development, parent-teacher conferences, or grade reporting when students do not attend. Some districts use early release or late start days for teacher collaboration. Schedules are communicated through district calendars, school newsletters, and parent messaging tools.

Families with children in more than one district or at more than one school level should check each calendar, since schedules do not always match.

Emergency Closures and Weather Days

Winter weather is the main cause of closures. Idaho City sits at about 3,900 feet and Garden Valley is in a deep river canyon, and snow, ice, and freezing temperatures are common from November through March, with hazards on State Highway 21 over Mores Creek Summit and on State Highway 55 along the Payette River. Each superintendent decides whether to delay, close, or reroute buses, usually early in the morning after checking road conditions with transportation staff and highway crews. Summer wildfire danger and smoke can also affect schools, as the area has seen several large fires.

Because Idaho measures instructional time in hours, districts can often absorb a few lost days, though policies differ and some build in buffer time or extend the calendar. Announcements go out through district websites, social media, and automated calls and texts, and through Boise stations such as KTVB, KIVI, and KBOI, along with local radio and community pages.

Graduation and End-of-Year Schedule

Final exams for secondary students usually take place in the last week or two of the second semester. High school graduations at Basin High School and nearby schools generally occur in late May, often in school gymnasiums, and are major community events. Elementary schools typically hold promotion or recognition events in the final week.

Report cards and grades are available through each district’s parent portal, and families usually receive login information at enrollment.

Back-to-School and Registration Information

Registration is handled through the school serving your address or the district office, with online options varying by district. Re-enrollment typically opens in the spring, and new families can register throughout the year.

Typical required documents include:

• Proof of residency, such as a lease, mortgage statement, or utility bill
• A birth certificate or other proof of age
• Immunization records or an exemption form, as allowed under Idaho law
• Records or a transfer form from the previous school

Children must generally be five years old by September 1 to enter kindergarten. Supply lists are usually posted in July or August, and schools often hold open houses or meet-the-teacher events shortly before classes begin.

Special Programs and Their Calendar Implications

With small districts, specialty programs are limited, and students often use online and dual credit options. Idaho Digital Learning Alliance offers online courses statewide and is a common supplement for rural students. Dual credit is available through Idaho colleges and universities, including the College of Western Idaho and Boise State University, and college terms do not always match the high school calendar. Alternative or charter options may be available in neighboring Treasure Valley areas, and pre-kindergarten availability varies, so ask the district directly.

Athletics and Extracurricular Calendar Context

High school athletics in Idaho are governed by the Idaho High School Activities Association (IHSAA). Boise County schools compete in smaller classifications, and long travel distances to away games can mean early dismissals. Seasons are divided into fall, winter, and spring, and playoffs may overlap with exams or graduation, so athletes and families should check team schedules alongside the academic calendar.

State-Level Calendar Requirements and How Idaho Law Governs Boise County

The Idaho State Department of Education and the State Board of Education set minimum instructional time requirements in hours, which differ by grade level, and local boards of trustees decide how to meet them. The Basin, Garden Valley, and Horseshoe Bend districts have flexibility to set start and end dates, build in breaks, and choose their schedules, as long as minimum hours are met. For questions about state requirements, contact the Idaho State Department of Education.
