They are bound by policy and consensus to grant administrator or bureaucrat access only when doing so reflects the wishes of the community, usually after a successful request at Wikipedia:Requests for adminship. In like fashion, they are expected to exercise judgment in changing usernames, and in granting or removing bot flags on the advice of the Bot Approvals Group. They are expected to be capable judges of consensus, and are expected to explain the reasoning for their actions on request and in a civil manner.
Bureaucrats do not have the technical ability to remove admin rights from users or to grant other levels of access (they cannot assign oversight or checkuser rights). These actions are performed by stewards, a small multilingual group that serves all Wikimedia projects. Additional stewards are elected annually; for more information see Requests for permissions. Changes in user rights by stewards are recorded at Meta:Special:Log/rights.
These are instructions for bureaucrats, regarding bureaucratic actions and processes.
Promotions
Note: Like with Articles for deletion, requests for adminship can be closed by non-bureaucrats in certain cases, for example if the user has withdrawn the request or the outcome is very unlike to be positive (see WP:SNOW). Non-bureaucrats should be very careful in the latter case and only close RfAs when they are not in doubt. In such cases the requesting user should always be asked to consider withdrawal first.
Place the word "Final" before the parenthetic voting results, change "Scheduled to end" to "ended," and update the ending time and date to reflect the current time and date.
If there is a consensus, promote to admin or bureaucrat using Special:Userrights. If present, be sure to remove userrights made redundant by the sysop flag, such as rollback, accountcreator, and ipblock-exempt.
Be sure that the user has no history of abuse and that the request is in the best interest of the project. Check the changing usernames guidelines and use your judgement.
