Surveys are created and deployed to students in the same way as Blackboard Tests, however, survey results are anonymous. Surveys in Blackboard are intended to gather opinions from students where they can reply honestly because their anonymity is protected. As a result, when you download survey results, the results will not include any information that identifies each user.
