The purposes of this study were: to identify indicators of an effective unit program in Virginia and to test the indicators identified to ascertain their usefulness as an extension program evaluation instrument. Fifty (50) extension agents participated in this study which used a modified Delphi research technique. Three (3) probes were sent to the agents and a field trial was conducted in fifty-four (54) extension units (nine (9) units for each extension district) by the district chairpersons. Probe I requested study participants to submit one-liners which were indicators of an effective unit program. These statements were categorized and synthesized into thirty-eight indicators for probe II. The second probe asked the participants to indicate the extent of agreement or disagreement with the items, thus ranking the indicators according to importance to program quality. Probe III utilized the results of previous probes and ascertained the strength of each indicator. / M.S.
