A Student code does not provide full access to ABCmouse from home.
Please note that the ABCmouse Teacher account used at school is a separate and different account from a paid Family subscription at home. The limited-access Student code will give a child access to all the lessons assigned by the teacher.
Applying a Student code to an existing account does not overwrite a paid subscription. If a family already has a paid Family subscription, the regular billing will continue.
If families do not have a paid Family subscription, they can upgrade to a paid full-access subscription to ABCmouse, but they are not required to do so to access the lessons assigned by the teacher.
