This plugin allows only site members to add reviews to the BuddyPress members on the site. But the member can not review itself. And if the visitor is not logged in, the visitor can only see the listing of the reviews but can not review.
The review form allows the members to even rate the member’s profile out of 5 points with multiple review criteria. You can add multiple criteria for review. And you can change the positions of those Criteria. Review form shows on the member’s profile but you can show review form on another page just by shortcode.
This plugin provides the functionality to change review rating type and colours. BuddyPress Member Review plugin adds a widget for display top reviewed member listing.
