Membership Grades

There are two Chartered grades open for applications: Fellow and Member. For current students there is a Non-Chartered Student grade. Find out more about these Grades here.

Member (MCIOB)

The Chartered Membership grade brings many benefits, including the right to use MCIOB as a post nominal designation. You can also choose between the descriptor of Chartered Construction Manager and Chartered Builder. As a Chartered Member you will have the right to vote and apply to become a Trustee, and thus be able to actively participate in the management of the CIOB.

Chartered Members also enjoy other benefits such as access to over 500 events every year, free CPD resources from the CIOB Academy, complimentary subscription to Construction Manager Magazine* and access to our Library Information Service. Chartered Members can also use the CIOB logo as well as a number of products and services - please click here for more details*.


The non-chartered grade of Applicant is a pre-requisite for all new members who do not hold an existing ACIOB/ICIOB membership, and wish to become Chartered. You must meet the eligibility requirements and be admitted to this grade in order to undertake your next steps to becoming Chartered. The Applicant grade does not provide any entitlement to post-nominals or designations, however by progressing through the most appropriate route to membership, you can gain your Chartered Membership and enjoy all the benefits that come with being MCIOB.

Fellow (FCIOB)

The Fellowship grade is the highest award offered by the CIOB. Our Fellows are amongst the most experienced and knowledgeable professionals in the construction industry, recognised globally for their skills and achievements throughout their career. The associated post nominal, FCIOB, is highly regarded and sought after. Entry to Fellowship is focussed on meeting a unique set of leadership competencies and behaviours at a strategic level, reflecting the highest level of professional competence.

Benchmarked at Level 7 by ENIC and comparable to Master's degree level, Fellowship applications are open to senior professionals with more than 5 years experience of leading an organisation, leading people and contributing to the industry, communities and/or society.

In addition to receiving the benefits of Chartered Membership, becoming a Fellow of the CIOB can bring considerable additional rewards, including employer achievement recognition, career progression, promotion, higher salaries and a wider range of job opportunities.

After retirement, Chartered Members and Fellows can apply for the Retired Grade. Once accepted, new designations can be used: Ret MCIOB for Members and Ret FCIOB for Fellows.


Student membership is our entry point to membership for those who are either studying full-time or part-time, alongside employment. There is no professional review and no post-nominals, so Student membership is not classed as Chartered Membership. It is, however, a great starting point for any students wishing to enter into Chartered Membership in the future.

Student membership gives you instant access to a wealth of resources that will support your transition to a worthwhile career. We welcome students from around the globe and from a wide range of disciplines including construction, architecture, engineering, environment, design conversation and many more.

If you are studying full-time without employment, you can apply for our free student membership. If you are studying and employed, you can apply for our part-time student membership for a small annual fee.

Discontinued grades

The Associate (ACIOB) and Incorporated (ICIOB) grades closed to new members in 2015. They were were intended to be stepping stones towards Chartered status. For current ACIOB and ICIOB members, your status will remain unchanged until June 2025. At this point, we expect that you would have upgraded to Chartered status.

Associate membership was often awarded to those in a management position for a couple of years with an academic qualification comparable to an HNC or other Level 4 qualification. The Incorporated grade was one step above Associate, and was intended for fairly experienced managers with the equivalent of a foundation degree, HND or Level 5 qualification.
