Each year, a committee of parents, teachers and administrators meet to develop the district calendar before submitting it to the Board of Education for final approval. Missouri law requires public schools to start no sooner than 14 calendar days before the first Monday in September. In addition, school years are counted in hours instead of days, which gives districts more flexibility in how they manage inclement weather days.
