What document assists recruiters in defining criteria for test participants?

The Recruitment Screener is a crucial tool used by recruiters to define the specific criteria for selecting test participants for usability studies or user research. This document outlines the essential characteristics that potential participants must possess to ensure they fit the target user profile for the study. By establishing clear qualifications, such as demographics, experience, and relevant behaviors, the Recruitment Screener helps ensure that the participants recruited will provide meaningful insights relevant to the design objectives.

The importance of this document lies in its ability to streamline the recruitment process, making it more efficient by focusing only on candidates who meet the established criteria. This ensures that the results of the usability testing are valid and can be generalized to the intended user group, ultimately leading to more effective design solutions.

In contrast, while a Participant Tracker is useful for managing and tracking the participants who have been recruited, it does not define the criteria for selection. Similarly, a Usability Test Script is focused on guiding the testing process itself and does not pertain to participant selection. Meanwhile, a Project Plan outlines the overall project strategy and timeline, which is not directly related to the specifics of participant recruitment. Thus, the Recruitment Screener stands out as the document specifically designed to assist recruiters in defining the necessary criteria for test participants.
