UPDATE:
KCTC believes they have corrected the issue. If you have any issues calling the main school numbers and not getting through from this point forward, please call the main District number (319-653-1100), select one of the schools, and report the issue. It is helpful if we know the number you are calling from, which of the school phone numbers you called, and the approximate time you experienced the issue.
Thank you for your patience and understanding.
