Your QuickSchools account supports multiple languages as a built-in option that comes with all subscriptions. Individual users are able to set the language for their own login with the "Language" link in the the footer of their portal:
Each school can also set the default language for all users in their account. This screen is available to school administrators on the “Settings” > “School Profile” page. Simply click the "Change" button in the "Default Language" section:
If you have any questions, including/especially if you’d like us to support a new language that is not listed, do let us know.
