Assessment and program evaluation require that we look at the results of our assessments. However, stopping there would be futile. We must also follow through and act on the results. We must plan strategies to improve based on those results. That's the purpose of data-driven decision processes. It's okay, however, to say that nothing needs to be changed. In either case we need to assess again at regular intervals. Assessment is an on-going process. So, whether our strategy is to take some action or to leave things as they are, we must not forget to "occasionally look at the results."
