The process of evaluation is research. By addressing the efficacy of programs, policies, or our own interventions in our real life practice, we are conducting research about our own work. An example might be a social worker giving before and after surveys at the beginning of treatment, and then at the end, in order to compare client outcomes from beginning to end of treatment. The information gathered in the survey may show a pattern over time of where that treatment plan was effective, where it was not so effective, and what trends there are when it is used in many cases. Research is so important and beneficial to social work as the importance of the evaluation stage is to a social worker in their practice, as it is the gathering of information relevant to our practice which we can use to refine our interventions.
