Posttest Only
A posttest only approach asks participants to walk through a similar reflective exercise as the retrospective pre/post-test but only asks for one response. This approach is typically used for shorter-engagements and activities. It minimizes the survey onus on the participant in addition to the analysis required on the back end.

Follow-Up
Extension educators are expected to follow up with their participants to understand how their educational efforts influence practices and behaviors. These follow up surveys may also be structured to collect impact data centered on changes to social, economic and environmental conditions. The example below provides an example of a set of questions focused on making progress towards a set of practices. While the questions below are specific to agriculture, you can use the overarching framework and simply switch on the practices to match your program context.
As a result of this Extension training, have you made any progress with regard to the following practices? Yes No
Applying conservation tillage practices?
Following a crop rotation?
Following minimum tillage practices?
Using crop residue as a ground cover?
Using cover crops?
