The CTOS web campus provides DHS/FEMA certified courses regarding radiological and nuclear Weapons of Mass Destruction topics to our nation's emergency responders. Some courses are for entry-level understanding and are designed to help students prepare for additional CTOS instructor led training. Other courses are designed as refresher training for those that have already completed an instructor led class taught by CTOS.


All CTOS courses are offered at no cost. Access to the web campus is available 24 hours a day, 7 days a week to registered users, other benefits include the ability to study at your own pace, earn continuing education credits, and print completion certificates from your account.


If you are having difficulty accessing the web campus, and need assistance send an email to support@k2share.com or call 877-612-HELP (4357). The Help Desk hours are 7:00am - 7:00pm (CST) Weekdays.
