Schools calendars provide families with a snapshot of the entire year.
Holidays breaks, the first day of school and professional development days vary school by school, so it’s a great idea to keep it handy. If no emergency days are used, the last day of school will be May 21, 2024; if all emergency days are used, the school year will end May 29. Here is the 2023-24 school calendar as approved by Community High School District No. 155’s school board.
Here are a few key dates you’ll want to bookmark:
