Derby seniors walked out of the high school for the last time without even knowing it on March 13.

The Class of 2020 still had a calendar with plenty of events to keep them busy with prom, spring sports and, of course, graduation.

That all ended on March 17.

“Derby Public Schools will be closed for the remainder of this school year,” stated the post from superintendent Heather Bohaty on the district Facebook page.

Many seniors will not be able to play their favorite sport or take classes because of COVID-19. The coronavirus continues to quickly spread through the world, so precautions have been taken to slow its spread by shutting down schools and keeping groups to a 50-person maximum.

“As Kansas we have always done what is necessary to protect our families, this moment is no different,” Gov. Laura Kelly said.

The Class of 2020 will get to ring the bell at some point, though.

“Seniors of 2020 you will ring the bell. I promise you. You will ring the bell,” principal Tim Hamblin wrote on his Twitter account.

More information about how education will continue will be announced over the next few days.
