Periodically, Louise walks through the room, collecting the non-active numbers and
sorting them by disposition (e.g., ineligible, completion, etc.), and collecting the active numbers
for redistribution. Call-sheets for completed interviews are attached to the hardcopy of the
completed questionnaire. Louise sorts the active numbers by priority, placing the numbers that
need to be called back soonest and are highest priority. Louise ensures that “no answer” call
backs are redistributed among interviewers so that the telephone numbers are tried again in two
hours. If a telephone number has been tried six times without resulting in a completed interview
or a scheduled callback to complete an interview, Louise gives this telephone number a
disposition of “never available” and moves it to the stack of non-active numbers.
