Our school sometimes has to either split classes or merge them during the school year, due to the student numbers changing dramatically for various reasons. When we have to split classes mid-year, the children would lose access to their Portfolio, so what we've been doing is keeping the students in the same class as they were, and then teachers go between two classes on Toddle instead. We'd love if Toddle would consider making splitting or merging classes something we can do mid-year with the option of transferring the Portfolio's as well.
