The school calendar is accessible via the Parent Portal (FACTS SIS formerly RenWeb). One of the best features of the calendar is the ability to subscribe and have it synced to your personal calendar. To subscribe, log into FACTS SIS and click on Calendar. Once in the calendar, click on subscribe. There you will be able to select the calendars you would like to subscribe to and get a link to paste in your personal calendar.
Here are links to the PDF versions of the school calendars. The most up to date calendar information will always be through the Parent Portal.
