During the afternoon of Friday, December 20, we will be conducting a test of our emergency mass notification system. During the test of this system, called Alertus, will activate both the emergency beacons across campus and the associated app that some have downloaded. While we will change the alert notification language to explicitly reflect the fact that it is a test, we want to let you know in advance so that you will not be surprised by any notice you may receive or activity you may observe on campus. If you have any questions, please be in touch with Michael McSorley at michael_mcsorley@concordacademy.org.
