I can see why parents of children who have SEN would think this includes their children, the first paragraph listed behaviour that can be typical in children with SEND (all the listed behaviours apply to my son)
The second paragraph states that labelling such behaviours is pointless or indeed stigmatising those students who display some or all of these characteristics.
Historically parents who suspected that their children had some kind of SEN and asked for referral for a formal assessment were asked why they were seeking to label and stigmatise their children, they were often told that a diagnosis would not help their children or get their children any support, their fears were not taken seriously and they were fobbed off, added to that parents were initially blamed for their child's behaviour and were forced into parenting courses often with disastrous results for their child.
Unfortunately parents are still being told the same things, still being fobbed off, medical professionals still refer to a diagnosis as a label as do many teachers, senco's, headteachers, social workers, LEA SEND Advisors, Caseworkers etc.
Think about this for a minute; Epilepsy is never called a label, it's a diagnosis, Alzheimer's is never called a label, it's a diagnosis, Down Syndrome is never called a label, it's a diagnosis, Asthma is never called a label, it's a diagnosis, Edwards Syndrome, Patau Syndrome, Prader Willi Syndrome,Treacher Collins Syndrome, Opitz G BBB, HLHS, HRHS, Talipes Equinovarus, Cerebral Palsey and many more are all things that are diagnosed, ergo they are always a diagnosis and always referred to as a diagnosis.
Autism
Asperger's Syndrome
Attention Deficit Hyperactive Disorder
Attention Deficit Disorder
Pathological Demand Avoidance
Rhett Syndrome
Dyslexia
Dyspraxia
Dysgraphia
Dyscalculia
And other things
All these are diagnosed by professional people, ergo they are always a diagnosis and yet all of these are continuously referred to as a label, Why?
A label is something you see on a jam jar, a tin/aluminium can, a label is something you put on your luggage before going on holiday.
The word diagnosis should never be replaced by the word label as it devalues the actual diagnosis.
