How to conduct a telephone survey
Introduce the survey to each respondent.
At the beginning of each phone call you are expected to introduce yourself and the survey company, describe the topic of the survey and explain the demographics of the survey.
It's helpful to use dynamic language in your introduction.
Instead of " are you interested in taking a survey? " you might say something like " this is a very important survey designed to directly impact the services and programs available to your family. " tell each survey respondent how their contact information was obtained.
