Following an 'overwhelming majority vote' from its membership, the Institute for the Management of Information Systems (IMIS) has agreed to merge with BCS, the Chartered Institute for IT.
The agreement will see all IMIS professional members transfer into BCS membership.
BCS has said that the two organisations will work jointly to maintain standards and enhance the reputation of the profession "so that it is recognised alongside the more traditional professions of law, engineering etc."
BCS Group Chief Executive David Clarke, MBE, says: "We are delighted to be welcoming IMIS into the BCS group. This is a natural fit and reinforces both of our agendas to promote and represent the IT profession across the globe.
"Today IT is central to society and business, therefore it is important that we establish standards for those currently working in the profession, encourage the next generation to consider IT as a future career choice and raise awareness among the general public of the importance of the profession."
IMIS was established to foster greater understanding of the importance of information systems management, promote higher standards through education and training, and enhance the status of those engaged in the profession. It will now work with BCS to promote wider social and economic progress through the advancement of ICT science and practice.
"In deciding upon this merger we believe that together our organisations will offer the best opportunity for members to continue to meet their academic, professional and career requirements," said Professor Simon Rogerson, Chair, IMIS Council.
"This is a landmark event for the industry. It is a real opportunity to make a positive difference for society in general."
IMIS will be transferred into BCS membership with immediate effect.
BSC's David Clarke added: "BCS is delighted to be working with IMIS to develop an integrated approach which will enable us to collectively meet the needs of members, businesses and the profession much more comprehensively in the future."
BCS recently issued a statement fully supporting Education Secretary Michael Gove's new draft curriculum for GCSE Computing.
