What are you already putting in place within your college ministry to successfully assess its impact later on this semester?
Evaluation may take place after-the-fact, but preparing for evaluation before-the-fact might make the after-the-fact happen better. To do this, we may just have to get to thinking: What will I be looking for? How am I going to get that info? Can I evaluate along-the-way (mid-semester, mid-week, mid-event, mid-retreat) and adjust? Who will help me evaluate? Whose assessment – while not unimportant – might not matter as much?
(The first step of good evaluation, of course, is figuring out what purposes you’re aiming for in the first place.)
