Educators and Assistants can have access to several rooms, and it is the responsibility of the users with the 

"Management" profile to define the rooms to which each educator has access. 


See this article to see how the Manager configures which rooms each Educator/Assistant can access

From the moment you have access to several rooms you just need to select which room you want to access directly on the main screen:

By choosing a room, the app will be contextualized and will only show the children in the selected room.

If you belong to several classrooms you can choose the option "All" to access all the children at the same time :-)
