CECOS is the Naval Civil Engineering Corps Officers School, which offers classroom and online training in civil and environmental topics. CECOSWeb (this website) is the home of CECOS interservice and interagency training. You can learn more about CECOS at our navy.mil home page.

Use the CECOSWeb home page to find training modules available on this site. Click on a module title to start that training. If login is required and you are not yet logged in, you will be forced to log in at that time. If you don't already have an account, you can create one for free at that time.

Once you have registered, there is no need to re-register when you want to take a different course. CECOSWeb will keep track of many of the courses you take. (However, some courses do not require login, and do not track usage even if you are logged in.) Occasionally, you may be required to provide additional information about yourself (beyond what you provided during your initial registration) before being allowed to take a particular course. Please see our Privacy Policy to learn how we handle your personal information.

Using the red navigation bar to the left, you can (if you are logged in) go to My Account to update the information you gave when you registered, and to reprint certificates of completion for courses you have completed.
