Blackboard allows instructors to make come changes to a quiz once it has been deployed, without erasing the scores of students who have already taken it. To make such changes, locate the quiz through the Control Panel in whichever content area you have placed. Click the Modify button, then click the Modify the test link. You will be presented with this warning:
You are about to modify an assessment that students have already taken. Only textual changes to existing fields are allowed, for example to correct a typo or reword a confusing question. Note that after you make textual changes, existing assessment attempts (tests that students have already taken) will show the new text, not the original text.
- Do not change the number of points for a question.
- Do not add or remove questions.
- Do not add or remove answers or feedback.
- Do not change settings.
- Do not change attached files
If you need to make any changes other than textual changes, you should create a new assessment. Any changes other than textual changes to existing fields will invalidate existing assessment attempts and could corrupt the entire assessment and its Gradebook entries.
Click the Continue button at the bottom, then, when presented with the Test Canvas, click the Modify button.
