Jefferson County Illinois Schools Calendar

Roughly 6,000 students attend public schools in the Mount Vernon area and the surrounding villages of southern Illinois, and they do so across more than half a dozen separate school districts rather than one countywide system. That structure means no single calendar applies to every family, and start dates, breaks, and early release days can differ from one district to the next. This guide explains how those calendars are built, who sets them, and where to find the version that applies to your child.

School District Structure in Jefferson County

Jefferson County, Illinois, has its county seat in Mount Vernon, and its public education is split among several independent districts, each with its own elected board of education and superintendent. Illinois does not run schools through a county board, so no county office sets one calendar for everyone.

The largest pairing is in Mount Vernon itself. Mount Vernon School District 80 serves students in the elementary and middle grades, and Mount Vernon Township High School District 201 serves grades nine through twelve. Outside the city, smaller districts serve rural communities and towns. These include Bethel School District 82, Opdyke-Belle-Rive Community Consolidated School District 5, Waltonville Community Unit School District 1, Rome Community Consolidated School District 2, Summersville School District 79, and Field Community Consolidated School District 3. Webber Township High School District 204 in Bluford serves high school students from several of the smaller elementary districts in the southern and eastern parts of the county. A few districts that serve parts of neighboring counties also reach into Jefferson County, so families near the county line should confirm which district their address belongs to.

Each board is a locally elected body that meets on a regular schedule, usually monthly, with agendas posted publicly in advance under the Illinois Open Meetings Act. The superintendent’s office in each district handles day-to-day administration. At the state level, the regional office of education that serves Jefferson County supports compliance, teacher licensure, and truancy services, and the Illinois State Board of Education (ISBE) oversees all of them.

Jefferson County is a mix of a small city and farmland. Mount Vernon is the main population center, and many of the other districts are small, rural, and sometimes single-building operations. That affects calendars in practical ways. Rural districts with long bus routes may be more cautious about weather closures, and small districts often share staff, which can influence in-service scheduling.

Academic Calendar Structure

Schools in Jefferson County generally start in mid-August, which is typical for southern Illinois and earlier than most districts in the northern part of the state. The school year usually ends in late May or the first days of June, depending on how many weather days were used. Exact first and last days differ by district and by year, and I am not listing specific dates here because each board adopts its own calendar. Most boards approve the next year’s calendar between winter and late spring, so families can usually see the new year’s dates well before the summer begins.

The year is usually organized around two semesters, with the first ending near winter break in December or just after the holiday return in January. At the high school level, Mount Vernon Township High School operates on semesters with quarter-based progress reporting. Elementary and middle grade districts often report by quarter or trimester. Check your child’s school for the specific grading periods, since they determine report card timing and when interim progress reports go home.

Illinois law requires a minimum of 176 student attendance days each year, and ISBE expects districts to schedule a standard 180-day term, with the difference covering days that may be lost to emergencies. Districts also must meet daily clock-hour requirements for instruction. Districts in Jefferson County typically build calendars with 176 or more student days and add flexibility for emergency closures.

Bell schedules vary by building. As a general pattern, elementary schools in the area start between about 7:45 and 8:30 a.m. and dismiss in mid-afternoon. Middle schools run on similar hours, and high schools commonly begin in the 7:30 to 8:15 a.m. range and end between 3:00 and 3:30 p.m. Because the districts set times independently, a family with children in two districts, such as a student in a rural elementary school feeding into a township high school, may be coordinating two different schedules.

School Holidays and Breaks

Most Jefferson County districts observe a recognizable set of holidays and breaks, though each board sets its own.

• Labor Day: the first Monday of September, with no school.
• Fall break or Columbus Day/Indigenous Peoples’ Day: some districts include a short break or a single day off in October.
• Election Day: Illinois law makes general election days a school holiday statewide, so districts schedule it off in November of even-numbered years.
• Veterans Day: observed by some districts, with ceremonies in others.
• Thanksgiving Break: usually the Wednesday through Friday of Thanksgiving week, and sometimes the full week.
• Winter Break: typically about two weeks spanning Christmas and New Year’s Day.
• Martin Luther King Jr. Day: a no-school day on the third Monday of January.
• Lincoln’s Birthday or Presidents’ Day: Illinois recognizes Lincoln’s Birthday on February 12, and many districts schedule a day off around Presidents’ Day in February.
• Spring Break: usually one week in March or early April, often near Easter.
• Memorial Day: the last Monday of May.

Dates move each year, so treat this list as a pattern rather than a schedule. For the exact dates, use the calendar the district’s board has adopted for the current year.

Here is a quick way to compare calendars if your family or relatives span the region: our Jefferson County schools calendar page tracks the pattern for this area, while the Jasper County schools calendar page covers a county elsewhere in southern Illinois, which is useful if you are moving between counties or have a child splitting time between households.

How to Find the Official Jefferson County School Calendar

Because there is no countywide calendar, begin with your child’s own district. Each of the districts named above maintains a website, and the board-adopted calendar is usually posted as a PDF under a heading such as “District,” “Parents,” “Families,” or “Community.” The Mount Vernon districts and Webber Township High School tend to have the most complete online calendar pages, while some of the smallest districts post a simple PDF on the home page or in the board documents area.

Calendars are normally adopted at a regular board meeting in the winter or spring for the next school year, and the meeting packet or minutes will show the vote. If you cannot find the document, call the district office. Staff there can email or mail a copy.

Individual schools may also keep supplemental calendars for concerts, parent-teacher conferences, field days, athletics, and picture days. These are separate from the board calendar, and they are more likely to change during the year, so check the school’s page or app periodically.

Early Release Days, Teacher Workdays, and Professional Development

Students do not attend every day on the district calendar. Teachers typically report a few days before students in August for workdays and orientation. During the year, districts schedule institute days and school improvement days, which are no-attendance days used for training. Illinois requires certain recurring training for school staff, such as mandated reporter and other safety-related training, and districts fit these in during institute days or through shorter sessions.

Some Jefferson County districts also use early release days for staff collaboration or professional development. When these occur, they are listed on the district calendar, and families are reminded through the district’s messaging system, backpack notices, or social media. Plan for the earlier dismissal time on those dates, particularly if your child rides a bus, because bus routes run earlier as well.

Emergency Closures and Weather Days

Southern Illinois gets ice storms, occasional snow, severe thunderstorms, and tornado threats, and each of these can disrupt school. Closure decisions are made by the superintendent of each district, usually in the early morning after checking road conditions with the county highway department and local officials. Rural districts with long gravel or secondary road routes sometimes close or delay when Mount Vernon’s streets are fine, so a closure in one district does not mean closure in another.

Districts tell families through automated phone, text, and email alerts, website banners, and social media posts. Local media carry announcements as well. Radio station WMIX in Mount Vernon is a traditional source for closings, and regional television stations such as KFVS 12, WSIL, and St. Louis stations report closings across the area. The Mount Vernon Register-News also covers school news. Make sure your contact information is current in the district’s student information system so you receive alerts.

When days are lost, districts generally use emergency days built into the calendar or extend the school year at the end. In Illinois, a board can apply for a state waiver or use remote or e-learning days in some circumstances, depending on board policy, so a snow or ice day may not always mean a make-up day in June. Check your district’s board policy for how it handles this.

Graduation and End-of-Year Schedule

Final exams at the high school level generally fall in the last week of the first semester in December or January and again in the last days of May. Mount Vernon Township High School and Webber Township High School hold commencement ceremonies in May, often on a weekend, and the schools announce the date and venue on their websites and social media. Elementary and middle school districts typically hold promotion or recognition ceremonies for eighth graders and sometimes for kindergarten or fifth grade in the final weeks.

Report cards go home at the end of each grading period, and most districts offer a parent portal in their student information system for checking grades. Contact your child’s school office for login help.

Back-to-School and Registration Information

Enrollment generally opens in the spring for returning students and continues through the summer for new families. Online registration is increasingly common, though some small districts still handle enrollment in person at the school or central office.

Typical Illinois requirements include:

• Proof of residency, such as a lease, mortgage, or utility bill.
• A certified copy of the child’s birth certificate.
• Immunization records and, for certain grades, a physical exam and dental exam as required by the state. Illinois requires health and eye exam documentation for specified grade levels.
• Prior school records for transfer students.

Supply lists are usually posted on district or school websites in July, and many schools hold open houses or meet-the-teacher evenings in the week before classes start. Check the school calendar for the date.

Special Programs and Their Calendar Implications

Pre-K programs, including those funded through Illinois’ Preschool for All, may run shorter days or a different schedule than K-12 classes. High school students can take dual credit courses through Rend Lake College, in nearby Ina, and college classes follow the college’s calendar, which differs from the high school’s for start dates, breaks, and finals. Career and technical education offerings may also run on separate schedules or include transportation to and from another campus. Students in alternative education or online options should confirm calendars with the program directly, since they may not follow the regular building schedule.

Athletics and Extracurricular Calendar Context

High school sports and activities are governed by the Illinois High School Association (IHSA), which sets season start dates, practice limits, and postseason tournaments. Local athletic schedules are set by individual schools and their conferences, and they often continue during parts of breaks, for example holiday basketball tournaments in late December. State playoff schedules can also run past the school’s last day of classes, so keep an eye on the athletic calendar as well.

State-Level Calendar Requirements and How Illinois Law Governs Jefferson County

The Illinois School Code sets the minimum attendance days, daily instructional hours, and required holidays. ISBE enforces those standards and reviews district compliance, and local boards then decide how to meet them. Boards cannot shorten the year below the legal minimum, and they must observe legally required holidays such as Election Day. Beyond that, local boards have wide discretion to set the start date, breaks, and in-service days, which explains why neighboring Jefferson County districts can look different from each other.
