Bonneville County Idaho Schools Calendar

Bonneville County, Idaho is served by three school districts in the upper Snake River valley, with Idaho Falls District 91 and Bonneville Joint District 93 together enrolling most of the county’s roughly 25,000 public school students. What sets the calendar apart is a large, fast-growing eastern Idaho hub where a city district, a suburban district, and a small rural neighbor each adopt their own schedule under the same state rules.

School District Structure in Bonneville County

Bonneville County sits in eastern Idaho, with Idaho Falls as the county seat and the region’s largest city. Public education is divided among independent districts, each governed by a locally elected Board of Trustees and led by a superintendent.

• Idaho Falls School District No. 91, based in Idaho Falls, serves the city’s core with Idaho Falls High School, Skyline High School, and a range of elementary and middle schools, along with the Compass Academy charter school.
• Bonneville Joint School District No. 93, based in Idaho Falls, serves the fast-growing areas around Ammon, Iona, Ucon, and the surrounding countryside, with Bonneville High School, Thunder Ridge High School, and Hillcrest-area campuses.
• Swan Valley Elementary, a small school in the upper Snake River valley near the Wyoming line, falls under Bonneville Joint School District No. 93 and serves a very rural community.
• Public charter schools in the Idaho Falls area, including Idaho Arts Charter-related programs and others, operate under their own boards and set their own calendars within state requirements.

Each board meets on a regular monthly schedule, with agendas and minutes posted on the district websites. Because the districts are independent, start dates, break weeks, and last days of school can differ even for families who live a few miles apart.

Families who move around Idaho often compare how different parts of the state schedule the year. The Bonner county schools calendar shows how a lakeside district and its smaller neighbor in the northern Panhandle plan around heavy snow and tourism, while the Bonneville county schools calendar shows how a city district and a growing suburban district in eastern Idaho each set their own breaks and start dates. Reading both explains why a school year in Sandpoint may not line up with one in Idaho Falls or Ammon.

Bonneville County is a mix of urban, suburban, and rural communities. Idaho Falls is the urban core, Ammon and Iona are growing suburbs, and Swan Valley and the Ririe area are small and spread out. Proximity to the Idaho National Laboratory shapes the local workforce and draws families who relocate for work, which affects enrollment, boundaries, and bus routes.

Academic Calendar Structure

Bonneville County districts generally begin the school year in mid to late August, with teachers reporting a few days earlier, and finish in late May. 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 middle and high schools 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.

School day hours are set locally. Elementary, middle, and high schools in Idaho Falls and Ammon run on different bell schedules, and times can shift as districts add schools or adjust boundaries. Check your school’s website or office for current times.

School Holidays and Breaks

Bonneville 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

Some districts add a fall break in October or extra days around parent-teacher conferences. These dates shift annually, so confirm them against the adopted calendar.

How to Find the Official Bonneville County School Calendar

There is no single Bonneville County calendar, so start with the district that serves your address. Idaho Falls School District 91 and Bonneville Joint School District 93 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 Bonneville 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 schools use regular 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 Falls sits at roughly 4,700 feet, and snow, ice, and wind with blowing and drifting snow are common from November through March, with hazards on Interstate 15, U.S. Highway 20, U.S. Highway 26, and rural roads toward Swan Valley and Ririe. 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.

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 eastern Idaho media such as KIFI (Channel 8), KIDK (Channel 3), and KPVI (Channel 6), along with local radio and the Post Register.

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 Idaho Falls, Skyline, Bonneville, and Thunder Ridge generally occur in late May, often at larger venues such as the Mountain America Center in Idaho Falls or on school grounds, 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 in both major districts. 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. Families relocating for work at the Idaho National Laboratory should confirm which district serves their new address before registering. 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

Both major districts offer alternative and specialty options, including career-technical programs, and public charter schools set their own calendars. Idaho Digital Learning Alliance offers online courses statewide, and some districts run their own virtual options with different timelines. Dual credit is available through Eastern Idaho Technical College, Idaho State University’s Idaho Falls campus, and other Idaho colleges, and college terms do not always match the high school calendar. Pre-kindergarten and early learning programs vary by district and often follow separate enrollment processes and calendars, 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). Bonneville County schools compete in conferences by classification, and seasons are divided into fall, winter, and spring. Playoffs may overlap with exams or graduation, and travel to away games can mean early dismissals, so athletes and families should check team schedules alongside the academic calendar.

State-Level Calendar Requirements and How Idaho Law Governs Bonneville 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. Districts such as Idaho Falls and Bonneville Joint have flexibility to set start and end dates, build in breaks, and choose their schedules, as long as minimum hours are met. Charter schools follow the same hour requirements while setting their own calendars. For questions about state requirements, contact the Idaho State Department of Education.
