 Gray 's Inn and the other three Inns of Court remain the only bodies legally allowed to call a barrister to the Bar , allowing him or her to practise in England and Wales . Although the Inn was previously a disciplinary and teaching body , these functions are now shared between the four Inns , with the Bar Standards Board ( a division of the General Council of the Bar ) acting as a disciplinary body and the Inns of Court and Bar Educational Trust providing education . The Inn remains a collegiate self @-@ governing , unincorporated association of its members , providing within its precincts library , dining , residential and office accommodation ( chambers ) , along with a chapel . Members of the Bar from other Inns may use these facilities to some extent .
