Key features

This is a short report and toolkit  to explore impact assessment tools that could be adapted for different contexts. It is especially targeted to help organisations that work with street-connected children and young people  measure their impact.

The report explores impact assessment after interviewing a range of leaders and monitoring and evaluation experts from across the  street-connected young people sector in different countries. It explores how they define impact, why they measure it, how they measure it, how much time and brain space is given to impact assessment within their organisation and what the barriers are to being able to measure impact.

The toolkit contains 5 tools. For each tool an explanation is provided of what it  is, how you could use it, how you could adapt it and some of its limitations that you need to consider before using it. Alongside this, are some adaptable versions of the tools and examples of how they have been used within organisations that work with street-connected young people  in the UK, Uganda and India, including an audio tour “sense our streets”.

Who is this resource useful for?

  • Advocates for evaluation;
  • Commissioners/managers of evaluation;
  • Evaluators;
  • Those involved in evaluation capacity strengthening​

How have you used or intend on using this resource?

This toolkit is focused on 5 tools to support an  impact assessment  catering for different needs. They have been adapted for use by  smaller organisations working with street-connected children. 

1. Theory of change (exploring your impact framework and how you would get there) 

2. Tree of change (exploring some of the more significant changes your service users have experienced) 

3. Wellbeing – then and now (exploring distance travelled around important indicators) 

4. Wheel of attribution (exploring how much of the change was because of your services) 

5. Turning point poetry (exploring the turning points your service users have experienced)

This toolkit has been adapted and tested with organisations working with street-connected young people in the UK, Uganda and India in 2015 and has case studies included of how they used the tools and what they learnt from using them.

Why would you recommend it to other people?

This is a  toolkit for anyone who is interested in exploring impact assessment with young people in creative ways. 
It  offers all the tools in an adaptable format so they can be easily altered for an organization’s  specific situation.
