Truth Project

The Inquiry's Truth Project focused on providing the opportunity for victims and survivors of child sexual abuse to share their experiences of abuse. It came to a close in October 2021 so that accounts shared could help to inform the Inquiry's Final Report. Here are the final figures for the Truth Project.

Research and Seminars

The Research team brings together, in one place, what is already known about child sexual abuse and finds the gaps in our knowledge. The team supports the Inquiry to ask the right questions of the Institutions it is investigating. It also carries out new research and is responsible for analysing the information the Inquiry receives through the Truth Project.
