How Parkway C-2 calls a snow day

How families hear

By phone call, text message, email, the district website, social media, local TV, radio and the district app.

“Notify families and staff using automated phone calls, text, and email notifications.”
Closings & Emergencies

A 2 hour delay

On a delay morning every school starts 2 hours late.

“On a snow schedule, all schools open two hours later than normal. Bus stop pick-up times are two hours later, and employees report to school two hours later than usual.”
Delay schedule

Remote learning days

Parkway C-2 has remote learning days in its winter plan.

“If we use three snow days this year, the fourth day would be a virtual learning day for students in grades 3-12. Students in early childhood and grades K-2 will complete a learning packet.”

The Missouri rule

How Missouri counts a lost day

Missouri requires at least 1,044 hours of actual pupil attendance, plus 36 make-up hours built into the calendar for bad weather. A district must make up the first 36 weather hours and half of any hours beyond that, but never more than 60 make-up hours in total; anything past that is excused.
