The emergence of a new, naturalistic, paradigm of inquiry has led to a demand for rigorous criteria that meet traditional standards of inquiry. Two sets are suggested, one of which, the "trustworthiness" criteria, parallels conventional criteria, while the second, "authenticity" criteria, is implied directly by new paradigm…

The user-oriented and utilization-focused evaluation design of the two-year Caribbean Agricultural Extension Project, funded by Aid to International Development, is reviewed. The evaluation scope, stakeholders, evaluation team credibility, official approval of evaluation, and confidence in the evaluation process are addressed, within a…

The nine articles of this theme issue provide overviews of legislative program evaluation and demonstrate the tensions caused by the conflict between utility and rigor in such evaluations.
