The Boulder Valley School District is closed Friday but says they expect high school athletic practices and competitions to take place as scheduled. However, the morning care programs and kindergarten enrichment will be canceled.

Superintendent Dr. Jan Marie DeLay of the RE-1 Valley School District says the district understands and respects their teachers' ability to walk out, but added, "However, we regret this action is taking place during the school day and impacting students."

Denver Public Schools, the state’s largest school district, is canceling all classes on April 27 due to the protest. Until late Monday night, the district said they were just having a short day.

Aurora Public Schools says students will still be able to participate in extracurricular activities.

These announcements come the same week that dozens of teachers held a rally at the Colorado State Capitol that led Englewood Schools to cancel class for the day.
