2-Hour Delayed Start Days

Charleston CUSD#1 may run a delayed start schedule for all schools on severe weather
days. The delayed start schedule provides the flexibility to begin school two hours later
than normal, allowing times for roads to be cleared and temperatures to rise. This
alternative eliminiates a situation where severe weather in the early morning leads to a
decision to close schools for an entire day when it is not warranted. This can be
everything from road conditions to freezing temperatures possibly even combined with
the early morning darkness which makes traveling by school bus challenging. Please
remember that parents should have a plan in place for "delayed starts". On
delayed start schedule days, buses will arrive at the scheduled pick-up points two
hours later than regularly-scheduled time. In the event a delayed start schedule is
utilized, school schedules will be adjusted as provided.
