Demonstrate your organisation’s positive impact

‘Impact practice’ refers to all the activities you do to demonstrate the positive difference that your organisation makes. It’s about learning how to best serve the people you support.

This means: 

  • planning what difference you want to make
  • collecting the right information to know if you’re achieving your goals
  • assessing what impact you’re having, and
  • learning from the results to improve your work.

It’s becoming increasingly important for voluntary organisations to be able to show the difference they are making and to be able to communicate this effectively to funders, beneficiaries and the public. 


For help in taking the first steps towards measuring, understanding, and improving your impact visit the NPC website which contains a range of tools and clear practical guidance: Starting to measure your impact

The NPC guidance provides:

  • a step-by-step approach you can adopt (called the Cycle of Good Impact Practice)
  • a jargon buster guide
  • a diagnostic tool on what data to collect and how
  • information on the principles that should inform impact practice (the Code of Good Impact Practice)

These resources have been adapted from the Inspiring Impact programme, which ran from 2011 until early 2022 and supported voluntary organisations to improve their impact practice. WCVA was a partner in this programme from 2017.
