School Closing and Schedule Changes

School buildings and campuses are closed to all teachers, staff and students except operations and other staff members working to clear campuses of snow or other weather conditions. 

All community activities scheduled for before, during and/or after school in school buildings or on campuses are canceled. 

All community activities scheduled in school buildings in the evening (including Community School, college classes, and community athletic programs) are also canceled. 

• If school is delayed for one or two hours, please add one or two hours to your normal bus pick up time or normal school start time to determine the delayed start time of school. 

  • High School Regular Operating Hours: 7:25 a.m.-2:30 p.m.

  • Middle School Regular Operating Hours: 7:25 a.m.-2:30 p.m.

  • Elementary School Regular Operating Hours:

    • "A" Schools: 8:35 a.m.-3:15 p.m.

    • "B" Schools: 8:50 a.m.-3:30 p.m.

    • "C" Schools: 9:05 a.m.-3:45 p.m.

    • See the section below for which schools are A, B, or C
       

• Full-day kindergarten pioneer schools will follow the same schedule as grades 1-6 students at their school. 
   

• See the section below for the delayed opening schedules for half-day kindergarten students.
   

• For MBIT: If CBSD and MBIT have a two-hour delay, AM MBIT students do not attend MBIT. They should take their normal transportation to their high school and report to study hall until third block begins. Alternatively, they may provide their own transportation to school to arrive in time for third block.

Occasionally, schools need to close early due to weather, emergencies, or planned afternoon teacher in-services. In cases of forecasted inclement weather, parents should be alert to the possibility of an early dismissal and have established and shared plans with their children. The district may need to dismiss schools early for up to one half hour without formal notice. 

In the event of an early closing due to a weather emergency, the middle schools and high schools will be dismissed first, followed by the elementary schools. At the elementary level, all "A" schools will be dismissed first, followed by the "B" schools, followed by the "C" schools as the busses become available. 

The standard early dismissal schedule is: 

• High School: 10:40 a.m. 

• Middle School: 10:45 a.m. 

• Elementary School: 11:55 a.m. ("A" schools); 12:10 p.m. ("B" schools); 12:25 p.m. ("C" schools) 

Parents are discouraged from picking up students at school during a weather closing until after bus dismissal. Too many buses, walkers and cars affect the safety of all students during dismissal procedures. 

Many Home and School associations in the schools coordinate a "snow chain" to call parents in the event of a closing, late start, or early dismissal. Snow chains, however, are only courtesy calls. 

During a weather-related emergency, schools will follow the instructions and contacts listed on the emergency contact information on file in the Parent Portal. If the information for your family needs to be updated, please contact your school office. (Please do not call the school to request any changes during a weather-related emergency situation.) 

Please understand that in inclement weather conditions our bus drivers are expected to use extreme caution to get our students home safely, and delays can be common. 

If there are any make-up dates required due to school closures, these will often take place following the last scheduled day of school. Graduation for the Class of 2027 at all CB high schools is scheduled for Thursday, June 10, 2026, with the exact times to be announced.
