In most of our courses, the pre- and post-assessments for each project are the same exact quiz. Students take the pre-assessment to assess what they know at the beginning of the project and then re-take the same quiz at the end of the project to get a better idea of how much they have learned.
However, we have received feedback that most teachers/users would like these quizzes to be separated so that the attempts are more distinguishable on the quiz reports.
So far, the Illustrator Certification Course assessments have been separated; the Photoshop Certification Course will be done next. Then, we will continue to separate the assessments as each course is updated.
