This case study highlights how we collected and analyzed qualitative and quantitative data (mixed methods) to learn more about the landscape of leadership centers and their role in leader development. We used a concurrent triangulation data collection method. Qualitative data were coded from center websites using a deductive thematic approach. Quantitative data were collected through an online survey of the center directors. The case study shows how to select a sample, given limited resources, that will allow findings to be generalized to the population of interest. In addition, it presents how to use a center (not a person) as a unit of analysis. The case study also illustrates the importance of coding protocols for archival data, website pages in this case. Finally, the case study highlights how mixed methods is a useful approach to confirm findings collected in different ways. Using both methods enabled us to make conclusions about the leadership framework of the 69 leadership centers studied.
