Hi Jo,
This sounds as though it is being historically pulled through SIMS, and admin just need to update the SIM coding.
Pupils should be coded ‘K’ for SEND support or ‘E’ for EHCP. That is normally what is also requested at the time of the census. All other coding was scrapped before the current SEND CoP.
Hope this helps,
Kate
