This report provides results of a field pilot that was conducted in an effort to address respondent concerns about the burden associated with the number and type of contact attempts that are made during the Computer Assisted Personal Interviewing (CAPI) operation of the American Community Survey (ACS). This pilot employed a cumulative burden score stopping rule, and was conducted in August 2015 in roughly one quarter of the field geographies in which ACS interviewing was conducted. The results from the pilot will assist in preparing for deployment of the cumulative burden score stopping rule for the nationwide CAPI operations in the late spring of 2016.
