Project Overview > How to Select a Tool

Consideration #4:
Level of Evidence

What level of evidence is acceptable? There may be expectations in a workplace regarding the thoroughness with which a situational assessment has been developed. These expectations are usually found in the values or principles of a workplace program. If a workplace requires that a thorough evaluation be completed (i.e., reliability and validity measured), the tools labeled in this catalogue as "recommended" and identified as having been evaluated will be the ones of most interest. However, if other forms of evaluation are acceptable (e.g., process), then tools labeled as "promising" or tools with no evaluation may suffice.

It is also important to understand that if a situational assessment tool is to be adapted (e.g., the questions or methodology changed), then the reliability and validity measures will likely no longer apply, and the tool may not be considered as having had an evaluation completed.
