Walker Information operates two call centers in the U.S. and Canada with 150 stations equipped with Tel-ATHENA^TM CATI (Computer Aided Telephone Interviewing) Systems that allow for complex survey designs with skip patterns and other variation. Walker's telephone interviewers are thoroughly trained in both interviewing and customer service, and they receive additional project-specific training based on client requirements. To ensure quality, Walker maintains a low supervisor-to-interviewer ratio and all booths are equipped with audio-monitoring equipment that can be used by clients for onsite or remote observations.

Walker Information offers its clients the flexibility to call anywhere in North America, Australia, the United Kingdom or France, using English, French, or Spanish speakers to conduct interviews. In addition, Walker provides an incoming toll-free service that allows hard-to-reach respondents to return calls at their convenience.
