The creator of a learning path can define who will approve answers to open questions. The creator will choose between the direct manager of the learning path participant, a specific person in the organization who will be in charge of approvals for the whole step/learning path or both. Learning admins and super admins will always be able to approve all responses.
The learning path creator can also provide reference instructions for the approvers if needed when creating the learning step, so you might see some instructions with your approval task. You will also see whether the user will need approval before continuing to the next step or if they can continue without waiting for approval.
You will find the 'Approval Dashboard' under the Learning module. Once you open it, you will see the tasks that are pending for approval. The tasks will be divided by the name of the task. If you want to see approved, resubmission required, or approval not required tasks, you can find these by filtering these statuses.
Once you select one or all the responses, you will see buttons at the bottom of the page to approve, request re-submission, or unselect.
