Feasibility Study for the Evaluation of DHHS Programs That Are or May Be Operated Under Tribal Self-Governance. Trade-offs Between Costs and Usefulness of an Evaluation


With any evaluation, the comprehensiveness, number of sites, types of comparisons, and amount of primary data collection affect costs.  A comprehensive evaluation, with a wide range of issues, a large number of sites, both pre-post and external comparisons, and extensive primary data collection would likely be costly, but also produce reliable and defensible results.  A very limited evaluation, with a few priority issues, a limited number of sites, pre-post comparisons, and minimal primary data collection, would be significantly less costly, but might produce fewer useful findings.
