Entrepreneurship Education: A road to success intervention (strategy, measure, etc.), linked to the global/general objectives of 3 the intervention. For the purpose of this study, the use of the term 8impact9 was not restricted to 8global impact9. In line with the definition above, it was often used to refer to immediate results and intermediate outcomes. Impact measurement An impact measurement was taken to be evidence from a study or a research project which shows that initiative 8A9 is a cause of the change measured on 8B9. This study draws evidence from several examples of impact measurement. The key requirement was that the studies were able to establish a causal link so that the impact (measured change) was clearly linked to a specific intervention. A considerable amount of time might have passed between an action (e.g. founding a company or becoming self-employed) and an educational activity. Other contextual and structural factors (family history, economic framework conditions) and other drivers of entrepreneurship outside of the educational system all have the potential to generate impact as well. Yet, robust and credible causal linkages between an intervention and specific changes need to have been established for the evidence to have been cited. 3 This definition was inspired by the guide 8Evaluating EU activities 3 A practical guide for the Commission services. 4
