School Closings / Delays

When inclement weather occurs, school closings or delayed openings will be announced on television channels NBC (5) AND ABC (8), either the evening before, or between the hours of 6:00 AM and 7:00 AM. E-mail notification will be made via FACTS Family Portal and announcements will be posted on the homepage of the school website, and on the school's social media accounts.

In most cases, St. Mark Catholic School will follow the same closing or delayed opening schedule as the Plano Independent School District (PISD).
