Youth Justice Board

NPC worked with the Youth Justice Board to provide theory of change guidance and training for youth justice practitioners.


The challenge

We worked with the Youth Justice Board to deliver training to practitioners in the youth justice sector on the value and practice of developing theories of change. YJB commissioned the training to help improve the quality of intervention design and evaluation across the sector, with the longer-term goal that this improved capability would lead to increasing evidence-based practice.

Our approach

We developed a tailored training package and during March and April 2014 delivered nine face-to-face training events to youth justice practitioners across England and Wales. We also held two online seminars, one each in May and June 2014, to target those who were not able to attend the face-to-face training and those who were interested in learning more and asking questions. Overall we had 181 training attendees, with representation from 106 out of 167 Youth Offending Services (63%). 80% of participants said that their expectations were met, 85% rated the event as good or excellent, and 76% said they would use what they had learnt.

We also developed written guidance on theory of change for youth justice practitioners, which was used in the training and then updated with feedback and learning from the events before being shared with the network. The aim of the guidance is to help youth justice practitioners use the theory of change approach to design and evaluate programmes, practice and processes.

The result

The guidance is available here and has already been viewed over 600 times. The online seminars are available via our YouTube channel and have been viewed over 180 times. You can download the slides from the second seminar here.

 Well delivered, interactive and interesting. Theory of change will be helpful in my work.

I feel it has focused me to look at what we do and why we do it, and has given me a tool to help with this.

I am going to implement it straight in to assessments and planning meetings and reviews.

Youth justice practitioners

We are still interested in seeing examples of theories of change that youth justice practitioners have created, and in providing you with feedback. For more information, please email
