This guide provides evaluators interested in new methods with a framework for determining the feasibility, utility, and effectiveness of the methods in field settings. To accomplish this intent, the body of this guide contains discussions of five checklists. Three of the checklists are to be used before a trial to determine the feasibility of one or more methods, and during and after a trial to determine the method's utility and effectiveness. An additional checklist lists factors related to ideal field trial conditions; deviations from these ideal conditions suggest the limitations that may be imposed on a method in a particular field trial. A final checklist contains an outline for recording the conditions and results of a field test. A brief summary of 27 method trials and an updated catalog of 38 new evaluation methods are appended.
