How do I re-allocate children into different classes on the analysis site?

There are two ways you can do this:

If it is just a few pupils, you can do this by going to the ‘Pupil list’ tab then click ‘edit’. That way you are able to change the pupil’s class from the dropdown.

If it is a significant number of pupils, then simply head to the ‘Classes’ tab, find the class you would like to move pupils to, then ‘Edit class members’. Select the pupils then click ‘Add’.
