Updating your personal information in the National Database While the president attempts to record your contact information accurately in the Canadian Ski Patrol National Database System (NDS), it is each patroller's responsibility for making sure their personal information is accurate and up to date. You can find the instructions on how to access the NDS here. Once you are connected to the National Database, click on the View/Edit your personal information link. Review all the fields to make sure they are accurate and up to date. Please note that the photo can only be changed by the zone president. If you want or need it changed, please send them an email.
