The Pennsylvania Certificate of Readiness (COR) is an administrative document issued by the Pennsylvania Department of Education to allow public and nonpublic schools to open and operate in compliance with state safety standards. It is a way for school districts to demonstrate that they are adequately prepared to provide a safe and healthy learning environment for students and staff. The COR is designed to ensure compliance with the Pennsylvania Department of Education's safety guidelines, including social distancing protocols, hand hygiene, and the use of masks. There are three types of COR's: the Initial Certificate of Readiness, the Extended Certificate of Readiness, and the Temporary Certificate of Readiness. The Initial Certificate of Readiness is issued to school districts that have demonstrated their compliance with the state's safety standards and are ready to open their doors to students. The Extended Certificate of Readiness is issued to school districts that have been in operation for at least 90 days and have demonstrated their continued compliance with the state's safety standards. The Temporary Certificate of Readiness is issued to school districts that are in need of an extension of their COR due to extenuating circumstances.
