Theresa clear legal definition of SEND in the Code Of Practice:
“A child or young person has SEN if they have a learning difficulty or disability which calls for special educational provision to be made for him or her”
If someone is dyslexic, *and* needs additional provision, then they have SEN.
If someone is EAL they don’t have a learning difficulty at all (unless they do as well, of course). But they need support to access the learning in terms of normal differentiation QFT and reasonable adjustments.
