What button must an active reviewer press to begin coding documents in an Active Learning project?

To begin coding documents in an Active Learning project, the active reviewer must press the "Start Review" button. This is a crucial first step in the workflow that transitions the user from preparation to the active reviewing and coding phase.

By selecting this option, the reviewer initiates the review process, allowing them to access and evaluate the documents assigned to them in the context of the project. This action not only signifies the start of their engagement with the documents but also ensures that the system tracks their actions for effective monitoring and analytics.

Other options, such as "Check Out Batch," "My Assigned Documents," and "Start Coding," do not represent the initial action required to begin the coding process. Instead, they may relate to managing batches of documents or accessing documents that have been assigned but do not directly initiate the active coding phase, which is critical for the project's progress.
