The Student/Coach relationships feature allows users to nominate a coach, who then receives access to otherwise hidden stats, such as the students' per problem mistake moves, play versus computer stats, tagging stats and FIDE rating estimates. Coaches can also edit their students' preferences, including assigning custom problem sets to students. Coaches have a new tab on their stats page showing a list of their students, and a summary of recent student accuracy. Coaches are also able to download problem history for their students, and can use the new problem history filtering on their students' problem attempts.
