What is an Approach?

Approaches (on this site) refer to an integrated set of options used to do some or all of the tasks involved in evaluation.
For example, we classify ‘Randomized Controlled Trials’ (RCTs) as an approach, which uses a combination of random sampling, control group and standardized indicators and measures.
Evaluation approaches have often been developed to address specific evaluation questions or challenges. For example, the Contribution Analysis approach has been developed to address questions about the feasibility of concluding that an intervention has contributed to an outcome in circumstances where a direct causal relationship is difficult to demonstrate.
