Review results are never auto-shared once they are submitted.
Admins can view all reviews as soon as they have been submitted. Admins can view review drafts during impersonation.
The visibility available to reviewers depends on the Review Cycle Deliverables set by the admin. Reach out to your HR team if you have any specific questions about what will be visible to you in your review cycle.
Review cycle deliverables
Self Reviews are visible to managers as soon as the direct reports submit their self-review if the Review visibility option Managers can see reviews as they're submitted has been enabled.
Peer reviewers can see the reviewee's self-reviews if the Peer Selection option Share the reviewee's self review with their reviewers has been enabled.
Peer Reviews are visible to the reviewee's manager once the peer has submitted them if the Review visibility option Managers can see reviews as they're submitted has been enabled.
Upward Reviews are visible as soon as either the packet sharer, typically the manager's manager or admin, shares the reviews with the manager. The manager will only have visibility into what a direct report has written for the upward review if those responses are shared with them.
Downward Reviews are visible to the direct reports when the reviewee's manager shares the reviews with them. The direct report will only have visibility as soon as they have confirmed the receipt of the packet.
