Parents are asked to contact the attendance office at their childs school to report excused absences. All weather-related tardies will be automatically excused Wednesday."A later statement from DPS said, "We are very concerned about the severely cold weather. Nevertheless, we expect road and traffic conditions tomorrow to have improved to the point to allow for buses to be fully operational, for our students to go to and from school safely, and for schools to be open to serve our students."Should parents decide that they want to keep their students home due to a safety concern related to the weather, those students will be given excused absences. We do not second-guess our parents when it comes to their childrens safety."See our updated list of closures here.To sign up to get a text alert when your child's school closes, just go to our text alerts page.
