To help policy makers and programme managers improve evaluation and think practically about how they can get it embedded at programme design stage, we have provided a number of case studies across our policy areas. Below we offer one example of where transport policy intervention has been evaluated for its impact on local economic growth in particular. (Read about our approach to this policy here).
Each evaluation case study has met our minimum standard of evidence, which means it (at least) compares what changed for the areas that benefited from an intervention with what changed over the same time frame for otherwise comparable areas that didn’t benefit, or that received a different type of intervention.
The case study uses a statistical approach to achieve this comparison. It tries to ‘strip out’ the impact of the other factors that could have affected outcomes in both the beneficiary group and the comparator group.
Evaluation need not be a very technical exercise and it can be helpful to borrow from the approaches adopted in existing studies. Read more about how to evaluate, and why we think it can be helpful to plagiarise in our How to Evaluate series. You can also read up on a number of different evaluation methods in our scoring guide to help you both judge other evaluations, and make a decision about which method to use.
This study examines the impact of road construction schemes carried out in Britain between 1998 and 2007. Read more
