We frequently get questions about whether quiz questions can be copied from one assessment to another within Schoology. Unfortunately, that is not specifically a capability in Schoology. However, there are other options for people looking to use questions on multiple assessments: Item Banks.
An item bank in Schoology allows teachers to store questions in centralized repositories. You can then pull these questions into any assessment from that point forward. You can also use this to create quizzes with a random selection of questions in a question bank to allow for multiple versions of quizzes.

As always, we invite you to reach out to me (firstname.lastname@example.org) or Amy (email@example.com) for help and advice in this or any other technology integrations!
