Other systems have a filter that you can add data fields into the gradebook so you can filter such things as language, ethnicity, EAL. otherwise you have to match up all these extra fields which is time consuming and not necessary when all the data is available with in the system. Currently you can only add form and SEN, so the feature is available it just needs someone to add more options to this feature.
We are targeting the addition of a built in EAL field to Student Registers. Once added we will then be reviewing the possibility of adding these fields to Gradebooks.
