Next Gen Math recommends using Secure File Transfer Protocol (SFTP) for sending your site's completed roster data template. To receive access to our SFTP Server simply request a username and password from your contact at Next Gen Math.
NOTE
If you are uploading templates for multiple sites be sure to place each set of templates within their own folders named after each site.
NOTE
If you are unsure how to connect to or send files through an SFTP server see How do I connect to an SFTP server with WinSCP?
