**Abstract**

The neurodiversity paradigm is reshaping how we understand, use language, interpret and undertake research, and support autistic people and those with related neurodevelopmental differences across the lifespan. Multi-disciplinary teams are seeking new ways to operationalise deficit focussed diagnostic criteria, to reflect the preferences of autistic people and the wider neurodiversity movement. In this chapter, we explore what the neurodiversity paradigm could mean in practice and how to reconcile the position that autism is a difference not a deficit and therefore individuals do not need to be "fixed" or "cured," with the continued importance of timely diagnosis and the very real impact on participation, engagement, and wellbeing of autistic individuals and their families, within the environments of home, education, community, employment, and care. We present work underway to move from "single condition" pathways to neurodevelopmental pathways and new approaches which consider co-occurring conditions in a single process, involve autistic people as partners and value differences.
