Evaluations sometimes report on how clients hear about programs, as well as their reasons for participating (or not). They report on:
- how programs are promoting themselves
- which promotions are reaching clients
- why clients participate
- what makes it more difficult for them to participate and/or
- why they don't participate.
To do this, evaluations tend to use existing documents or data on the promotions being used as well as participant surveys and interviews with key stakeholders.
