The ADCS EHE survey was  published recently and can be found  here

The survey was completed by 126 LA's (83%) and whilst it is disappointing  25 LA's (17%) did not respond this represents the most accurate count of EHE. AEWM will continue to push for compulsory registration as it remains committed to supporting all children, it is simply not good enough to only estimate around 81000 children are EHE. This of course is probably an under estimate as it does not take into account those children who have never attended school and parents are not legally bound to inform their LA.
