Four illustrative evaluation models were developed to provide a structure for assessing the feasibility of conducting an evaluation of DHHS programs managed under self-governance. These illustrative models range from comprehensive examination of a wide range of issues to a limited examination of targeted priority issues to very limited examination of issues using aggregate reporting data. In addition, the illustrative evaluation models for a new DHHS demonstration program are presented separately from the illustrative evaluation model for existing DHHS health programs that are currently compacted by Tribes.
Each of the four illustrative evaluation models are described in detail in Appendix D to this report, with respect to underlying assumptions, research questions to be examined, comparison group strategies, and data necessary for the evaluation approach. Below, each of these models is briefly described and feasibility considerations are discussed.
