Shiftleading Staff

Shift Leaders at work

The University of Wisconsin Survey Center retains a highly trained and professional interviewing staff. Before hiring an interviewer the UWSC conducts a personal interview, thoroughly checks the candidate's references, performs a mock interview, and administers a typing competency test. Only those who perform well in all areas are considered for the interviewing position. Besides a multi-day training period immediately after hiring, all interviewers attend study-specific briefings before a new project begins to ensure the interviewer is well prepared to deal with issues and answer questions from respondents pertaining to the study when they call. Interviewers are also monitored monthly by a Shift Leader to ensure high quality data collection.

Shift Leaders are generally promoted from the current interviewing staff and represent the best skills in communication, supervision,interviewing, instructing, and motivating. Shift leaders are responsible for the day-to-day operations of the Survey Center as well as maintaining a highly positive and professional work environment.
