Based on feedback from respondents and government agencies, the Census Bureau identified topics on the American Community Survey (ACS) that may require changes or additions. To evaluate these potential changes, new or modified questions are pretested using cognitive testing methods before being added to the actual survey. As part of the 2016 Content Test, the Census Bureau contracted with Westat to conduct cognitive testing of potential questions related to the following topics: 

• Hispanic origin and race
• Telephone service
• Computer and Internet use
• Health insurance
• Cohabitation / domestic partnership
• Commuting mode
• Time of arrival at work
• Number of weeks worked
• Class of worker
• Industry and occupation
• Retirement income

From June 17 through August 8, 2014, Westat conducted 208 cognitive interviews for Round 1 testing, and from October 24 through November 20, 2014, Westat conducted 120 cognitive interviews for Round 2 testing. This report summarizes the results from these two rounds of  cognitive testing.
