Please see the below from the Archdiocese:
Following the announcement of a stay-at-home order by local government officials, the Archdiocese of St. Louis is extending the closure of all archdiocesan elementary and high schools—including all grades pre-K through 12—through Wednesday, April 22. Pending continuing updates and guidance from local and state government and health officials, we have preliminary plans to permit teachers to return on Thursday, April 23, and students to return on Monday, April 27.
Archbishop Robert J. Carlson has told school administrators that the closing of our schools is the best path forward to help mitigate the spread of the COVID-19 virus in our area. All archdiocesan schools are providing distance-learning programming to students and families for the duration of the closures.
