9 pages, A new method for evaluating the influence of Extension programming involves exploring whether Extension clientele differ from others in knowledge and behavior related to a particular topic. Analysis of South Dakota farm survey data allowed for the assessment of potential impacts of Extension through comparison of knowledge and adoption regarding soil conservation practices among farmers who did and did not use Extension. Results suggest that, controlling for some farmer and farm characteristics, use of Extension is associated with higher levels of knowledge and greater adoption rates. The new evaluation methodology can be used for assessing broad-scale impacts across Extension program areas.
