In the carer sign up process, you will be prompted to choose relevant files. Follow the instructions.
The simplest way is to take a photo of the document with your phone and upload it directly to your sign up form.
You can save and come back to your application at any time up to registration. Post registration you can amend your profile at any time except for ID and qualification documentation, which will have to be verified by the Curam carer support team. Contact the team on firstname.lastname@example.org
