During its second meeting held in 2004, the IRHA Board of Directors decided to formalise the membership to the Alliance; as this would build a stronger organisation and create a sense of belonging to a worldwide network.


Following this, the IRHA Secretariat introduced a small membership fee. The fee was kept low as the real purpose of this action is not financial, but for the institutional strengthening of the RWH movement. By keeping the fee low and by choosing, for most of the categories, a single entrance rather than annual fee, it enables anyone to become a Member.


For more information on becoming a Member, including details on the different categories of membership, what is expected from our Members and the advantages Members can benefit from, please read our Membership Charter.
