As a private school, we do not use the standard DfE SEN flag/types (i.e. E, K, N etc). We have our own types and we managed them in Pupil Registers by creating the different flag/types in Configuration > Manage Sections > SEN > Register > Register Flag > Manage Items.
We have a couple of 3rd party tools that sync our iSAMS data via Wonde. Sadly, our customized SEN flags/types could not be displayed in these tools.
Please allow Wonde to pull customized SEN flags/data.
