I have created a qualification test for a study that just finished running on mturk. the purpose of the qualification test was to place respondents into one of two groups. The researcher who's running this study wants to make sure that no one who failed the qualification test the first time went back 3 days later and tried to retake it again. What I want to know is if there's any way to see the mturk IDs of those who have taken the qualification test. the 'evaluatequalificationrequests' and 'getqualificationrequests' don't pull up anything on amazon's CLT. Is there a different command I should be looking for or is there another way?
