Every year around the world, people spend a lot of time and money on campaigns to help children and young people stay safe on the internet. This investment is important because the online world can be a risky place, despite its many benefits. Online bullying and online grooming, for example, are far too common.

But how can we assess whether internet safety campaigns are making a difference? How do we know what are the best ways to educate and support children and young people to make good choices and stay safe online?

These questions are crucial, and evaluation is key to answering them. Evaluation helps us to understand more clearly how to improve what we are doing. Evaluation acts as a quality check and, when done well, it can help to solve problems and inform our decision making.
