Pilot Testing

Once you've developed your data collection tool(s), you'll want to pilot test your instrument(s) before you begin formal data collection activities. Pilot testing helps to:

  • Gauge how long the interview, survey, or focus group will take.

  • Identify issues that may need to be addressed when training data collectors, such as asking the questions in a standardized way.

  • Ensure instructions and questions are clear to the respondents.

You do not need to pilot test your instruments with a large number of people, but your pilot testers should be representative of your sample (or at least familiar with the perspective of the respondents) so that you are getting an accurate sense of how someone will actually respond to your questions. Typically, you will ask pilot testers to respond to your questions and then provide you with feedback about their experience (e.g., clarity, appropriateness of length). You may obtain feedback in a variety of ways, such as by having respondents make marks on a written copy of a survey (e.g., indicating unclear questions, missing response options, etc.), or discussing the instrument after they have gone through it. If there are certain items that you are particularly concerned about, be sure to flag these ahead of time so you can ask your pilot testers about these specific questions, too.

Once you've completed pilot testing and have made any necessary adjustments to your instrument(s), you are ready to begin data collection. Do not use the data you collected in the pilot test unless the respondents are part of your sample and you have not significantly changed the data collection instrument.
