Knox County Schools
Knox County Schools Calendar
The Knox County Schools calendar is established by a Calendar Committee that is made up of teachers, administrators, and district office personnel as well as parent representatives and the KCEA president who provide insight into scheduling needs across the system. Feedback from Regional Teacher and Parent Councils is also gathered early in the process.
Each spring, the Committee meets to consider feedback from regional councils, review draft calendars, and vote on a calendar to recommend to the Board of Education for the next school year. Once approved, the finalized calendar is published.
