The definition of ?disability? under the Equality Act 2010
In the Act, a person has a disability if:
-they have a physical or mental impairment
-the impairment has a substantial and long-term adverse effect on their ability to perform normal day-to-day activities
For the purposes of the Act, these words have the following meanings:
-'substantial' means more than minor or trivial
-'long-term' means that the effect of the impairment has lasted or is likely to last for at least twelve months (there are special rules covering recurring or fluctuating conditions)
-'normal day-to-day activities' include everyday things like eating, washing, walking and going shopping
-People who have had a disability in the past that meets this definition are also protected by the Act.
Progressive conditions considered to be a disability:
There are additional provisions relating to people with progressive conditions. People with HIV, cancer or multiple sclerosis are protected by the Act from the point of diagnosis. People with some visual impairments are automatically deemed to be disabled.

It may be worth quoting the above definitions of disability in your correspondence to the head, in case (s)he needs reminding of the definitions of disability that they as a school are legally bound to recognise and adhere to.
It's best to clear up any confusion on the school's part about what constitutes a disability before your disabled child attends their school.
