Wiltshire is committed to meeting the needs of children and young people with special educational needs and disabilities (SEND) and needing Alternative Provision (AP) living within the local area. This document is Part 1 of a population needs assessment focused on children and young people with SEND aged 0-25 years. The findings will inform robust decision making, set the strategic direction to improve outcomes for children and young people with SEND and their families in Wiltshire, and provide guidance for Part 2 of the needs assessment and ideas for future insight reports.
