From 2006 to present, the USA IAT was available on the Project Implicit Netherlands website (https://implicit.harvard.edu/implicit/netherlands/selectatest.jsp Click on “Landen” to try it yourself). The USA IAT includes one standard IAT (Good vs. Bad; Netherlands vs. United States), sets of explicit measures on attitudes related to the countries (such as preference for United States and Netherlands etc.), set of demographic questions (age, gender, race, major, political identity, etc.), and debriefing questions about how respondents thought about their IAT score after the task. The study is in Dutch.
From 2006 to the end of 2017, there are 15,621 session IDs created for the USA IAT, and the overall completion rate is around 38.4%. There are 7,091 respondents who completed the standard IAT part of the task, which is 45.4% of the total respondents.
