waiting list
Also called NHS waiting list for assessment. That is the name used in diagnostic manuals and on most official paperwork.
The queue for a specialist assessment once your referral has been accepted. Waits for autism and ADHD assessments are long in much of the UK.
Applies across the UK
Being on a waiting list means the service has accepted your child and is working towards an appointment. It does not mean anything is happening in the meantime, which is the hard part.
The NHS is direct about the length. On autism Autism Autism is a difference in how the brain develops. It shapes how an autistic child sees and experiences the world, how they communicate, and how they respond to things like noise, light and touch. Read the full definition of Autism : "If your referral referral When a professional passes your child on to a specialist team for assessment or treatment. A GP, school or health visitor can usually make one. Read the full definition of referral is accepted it can take a few months or longer to get an assessment." On ADHD: "waiting times vary and your child may have to wait several months or years for an ADHD assessment."
Two things are worth holding onto. First, support at school is based on your child's needs, not on a diagnosis, so it does not have to wait for the appointment. Second, contacting the service for an update is normal and keeps your details and your child's file current. If your child's needs get worse while you wait, tell the GP GP Your family doctor. For many families the GP is the first person to talk to, and the person who refers your child on to a specialist. Read the full definition of GP and the school rather than sitting on it.
Waiting lists exist across the UK. The specific waiting time rules differ by nation: England's general NHS maximum waiting time standard, for example, applies only to services commissioned by the NHS in England.
Across the UK
- NHS maximum waiting time standards (England) : The NHS guide to waiting times states the standards and the associated right to ask for a different provider "only applies to services commissioned by the NHS in England". Whether that standard covers a given neurodevelopmental assessment service is a local question, so it is not asserted in the body text.
