As the parent of a child recognised as autistic as a pre-teen or teen, it can often feel difficult to find the answers you need. Children who make it to late primary/early secondary age before being picked up by the system tend to present with traits that are harder to spot, meaning it can be harder to engage professionals in the diagnostic process and gather the necessary support. This handbook is tailored to support parents with older children or teenagers who are at the identification stage, walking them through the basics in an engaging and accessible manner. It addresses key challenges for this age group, including co-occurring conditions, puberty, and safeguarding, as well as looking to the future, advising on schooling options and beyond. Designed to help parents become fully informed and ensure a nurturing and positive environment for our autistic young people, this is a guide with a focus on difference - not deficit.
