In case the winter season does turn, all school closings/delays will be coming through our alert system in RenWeb. It is essential that you keep your cell number, home number and email address current in RenWeb. For instructions, please visit caschools.us/renweb. On this site, you will also find answers to FAQs about the alert service. This will be the first means of communication to families in regards to school closings or delays. You have the option to receive alerts via text message, phone call, email or a combination of these three.
