LaSalle County Illinois Schools Calendar

Roughly two dozen public school districts serve the families of LaSalle County, Illinois, a sprawling county in the Illinois Valley with some of the state’s most varied district structures. Because there is no single countywide school system, there is no single countywide calendar. Each district board adopts its own, so first days, break weeks, and end-of-year dates can differ from one town to the next.
School District Structure in LaSalle County
LaSalle County is a county in the Illinois sense, with Ottawa as the county seat. Its public education system follows the patchwork pattern common in northern Illinois. Elementary districts, high school districts, and a handful of unit districts operate side by side, and each is governed by its own elected Board of Education.
In the Ottawa area, students attend Ottawa Elementary School District 141 and then Ottawa Township High School District 140. Streator has a similar split, with Streator Elementary School District 44 feeding Streator Township High School District 40. In the Illinois Valley cities of La Salle, Peru, and Oglesby, students move through separate elementary districts, including LaSalle Elementary District 122, Peru Elementary District 124, and Oglesby Elementary District 125, before reaching La Salle-Peru Township High School District 120. In the western part of the county, Mendota Community Consolidated School District 289 and Mendota Township High School District 280 serve the Mendota area. Smaller communities such as Seneca, Marseilles, Earlville, Serena, Lostant, Tonica, and Grand Ridge are served by their own districts, including community unit districts and small consolidated elementary districts.
Each district has its own superintendent’s office and a published schedule of regular board meetings, usually monthly and open to the public under the Illinois Open Meetings Act. The LaSalle County Regional Office of Education, led by the Regional Superintendent of Schools, supports these districts with compliance, safety inspections, teacher licensure, and other administrative services. It does not set district calendars. Because many families live in one district for elementary school and another for high school, it is common for siblings to have slightly different calendars.
Much of the county is rural farmland, and the district sizes reflect that. Small rural districts often have more calendar flexibility but fewer transportation resources. The larger Ottawa, Streator, and Illinois Valley districts have more buildings, more bus routes, and more activities to coordinate.
Academic Calendar Structure
Most LaSalle County districts begin the school year in mid-August, with some starting closer to the middle of the month and others in the week before or after, and finish between late May and early June. Exact dates vary by district and by year. Boards typically adopt the following year’s calendar in winter or spring, and the dates are not the same every year, so treat any specific date you see elsewhere with caution until you confirm it with your district.
Most districts in the county use a semester system, with the first semester ending around the winter break in December or in early January and the second semester running through the end of the school year. Some elementary districts use trimesters or quarters for report cards even though the overall year follows a two-semester framework. Your child’s school handbook explains exactly how grading periods are divided.
School day start and end times differ by district and building. Elementary schools commonly start between about 7:45 and 8:30 in the morning and finish mid-afternoon. Middle and junior high schools tend to run at similar hours. The high schools, including those in Ottawa, Streator, La Salle-Peru, and Mendota, usually start between about 7:30 and 8:15 and dismiss in mid-afternoon. Check your own school’s published bell schedule, as these times are adjusted from time to time.
Illinois requires districts to provide at least 176 days of student attendance within a 180-day school term, and each full school day must include at least five clock hours of instruction. LaSalle County districts typically build their calendars with that 180-day term in mind, with attendance days, institute days, and holidays all counted toward it.
School Holidays and Breaks
Calendars adopted by LaSalle County boards share a familiar set of breaks, though the placement and length differ by district:
- Labor Day weekend, with school usually closed on the Monday.
- Fall break or a long weekend in October, which some districts add and others do not.
- Thanksgiving break, typically Wednesday through Friday or a full week.
- Winter break, usually about two weeks around Christmas and New Year’s Day.
- Martin Luther King Jr. Day in January.
- Presidents’ Day in February, though some districts use a different mid-winter day off.
- Spring break, generally in March or early April, often timed with Easter in some years.
- Memorial Day in May.
Illinois law also affects the calendar in a few ways. State law allows or requires a school holiday on Election Day in certain circumstances, and some districts also observe Casimir Pulaski Day or other days the board chooses. Because holidays move each year, always rely on the calendar your district board adopted instead of last year’s version.
Where to Find the Official LaSalle County School Calendar
Since each district is its own legal entity, the right place to look depends on where your child attends school. Start with the website of your district, such as Ottawa District 141, Streator District 44, La Salle-Peru District 120, or Mendota District 289. Most district sites post the calendar under a section labeled “District,” “Parents,” “Families,” or “Community,” and the board-approved version is often a PDF.
Calendars are normally approved at a regular board meeting, and the agenda and minutes for that meeting are posted online as well. If you want to know why a break was moved or a new day was added, those minutes are the best source. Individual schools also keep supplemental calendars for concerts, parent-teacher conferences, fundraisers, field days, and sports, which may not appear on the master district calendar.

Early Release Days, Teacher Workdays, and Professional Development
Not every day on the calendar is a regular student day. Most LaSalle County districts schedule teacher workdays before students return in August, when staff prepare classrooms and attend planning sessions. During the year, districts also set aside school improvement or institute days when students stay home and teachers attend training. Illinois requires certain recurring professional development for educators, and districts often use these days for state-mandated training on topics such as mandated reporting, bloodborne pathogens, and safety.
Early dismissal days are also common, often tied to staff training, parent-teacher conferences, or the days before a holiday break. Districts typically notify families through the calendar, a text or email system, social media, and a note sent home with students. In rural districts that bus many children long distances, early release days require extra coordination so families have time to arrange care. If your child rides the bus, call the district transportation office if you are unsure about pickup times on a short day.
Emergency Closures and Weather Days
Winter weather is the main reason schools close in LaSalle County. Superintendents make the decision, usually early in the morning after consulting road conditions, temperatures, wind chill, and the county highway departments, and sometimes in consultation with neighboring districts. Rural gravel roads and drifting snow across open farmland can make bus routes dangerous even when main roads in Ottawa or Peru are clear, which is why a rural district may close when a city district does not.
Closure announcements typically come through the district’s automated phone and text system, its website and social media pages, and local media. Residents commonly check Illinois Valley radio stations and newspapers, as well as Chicago, Peoria, and Quad Cities area television stations that cover the region.
Illinois districts build emergency days into their calendars and, when those run out, may add days at the end of the year. Illinois law also allows districts to use e-learning days, in which students complete work remotely, as an alternative to making up lost days, if the board has an approved plan in place. Whether your district uses e-learning, a makeup day, or an extended year will be stated in its policies or announced at the time of closure. Tornado season in spring can also lead to early dismissals or delayed starts on severe weather days.
Graduation and End-of-Year Schedule
Final exams for high school students usually take place in the last week or two of the school year, in late May or early June. The high schools, including Ottawa Township, Streator Township, La Salle-Peru, Mendota, and the smaller community unit high schools, typically hold graduation in May, often on a weekend or evening and at the school’s own gym, auditorium, or football field. Rain plans are common, so families should confirm the venue and time with the school a few weeks ahead.
Elementary and junior high schools in the county generally hold promotion, eighth-grade graduation, or end-of-year ceremonies in the final week or so. Report cards are sent home or posted to online parent portals, many of which are powered by student information systems that districts require parents to register for. Contact the school office if you do not have your login.
Back-to-School and Registration Information
Enrollment and re-enrollment for the following school year often open in spring or early summer, and new students are registered through the district office or the individual school, depending on the district. Families new to LaSalle County should expect to provide:
- Proof of residency, such as a lease, utility bill, or mortgage statement.
- The child’s birth certificate.
- Immunization records and a recent physical exam, as required by Illinois for specific grades.
- Proof of any custody arrangements and prior school records, if applicable.
Because attendance is determined by the district where you live, it helps to confirm your address on your district’s website before registering. Supply lists are typically posted on school websites in July. Many schools hold open houses, meet-the-teacher nights, or kindergarten orientation shortly before school starts, and those dates appear on the building calendar.
Special Programs and Their Calendar Implications
Some programs follow a calendar that differs from the standard one. Preschool and early childhood programs, including Illinois’s Preschool for All, may have shorter days or a different start date than the K-12 calendar. Students who take dual credit or college courses through Illinois Valley Community College in Oglesby may be affected by the college’s own academic calendar, which is not the same as their high school’s, so families should check both. Career and technical programs, alternative education programs, and special education services provided through cooperatives may follow the host program’s calendar, and bus schedules can differ as a result. Districts that offer virtual or hybrid options usually keep the district’s calendar but may handle testing and attendance differently.
LaSalle County has no widely known year-round public schools, but a family interested in a program with a modified schedule should ask the district directly.
Athletics and Extracurricular Calendar Context
High school sports and activities in Illinois are governed by the Illinois High School Association (IHSA), which sets the season dates, playoff schedules, and eligibility rules. These schedules run alongside the academic calendar and sometimes cross over breaks. Fall sports begin before the first day of school in August, and winter sports practices continue over winter break. Games and tournaments can also be scheduled around exam weeks, so student athletes should check both the school and team calendars. Junior high athletics are managed by the Illinois Elementary School Association (IESA).
State-Level Calendar Requirements and How Illinois Law Governs LaSalle County
The Illinois State Board of Education (ISBE) sets the minimum standards that LaSalle County districts must meet, and the Illinois School Code sets the 176-attendance-day minimum and the five-clock-hour school day. Boards must adopt a calendar that meets these requirements, and they can add days beyond the minimum if they choose. The state also regulates mandated school holidays, required teacher training, and the use of emergency and e-learning days. Within those limits, each district board has authority over start dates, break lengths, and daily schedules, which is why LaSalle County’s calendars vary even though the legal framework is the same.
