This webinar will look at the value of monitoring and evaluation in services responding to child sexual abuse, and set out some core principles. It will include explanation of key terms such as ‘data’, ‘outputs’ and ‘outcomes’, ways to develop outcomes and outcome measures for this group of services and methods for gathering data to evidence organisations’ activities (and their impact). A framework for thinking about this work will be described, including the use of Theory of Change model that allows for group discussion of aims and activities, and provides a visual representation of these. Learning from service users is a key part of this process, and we will consider issues in co-producing frameworks, and in how results are collected and shared. Our publication measuring your effectiveness - CSA Centre could also be useful for you.
