Former grades - Associate and Incorporated

The Associate (ACIOB) and Incorporated (ICIOB) grades closed to new members on 1 July 2015. 

This revision was made following consultation with members and the wider industry when a grade review identified a lack of clarity across the built environment sector about what ACIOB and ICIOB represented.

These grades were intended to be stepping stones towards Chartered status. However, our data has since suggested that many ACIOB and ICIOB members are already well qualified to progress to Chartered membership.

What does this mean for me as an ACIOB or ICIOB member?

For current ACIOB and ICIOB members, your status will remain unchanged until June 2025.

CIOB offers various tailored pathways for ACIOB and ICIOB members to become Chartered, including a time-limited Accreditation of Prior Experiential Learning (APEL) pathway to Chartership (available until 2024). APEL will rigorously assess your practical experience and knowledge in lieu of a Level 6 qualification.

You will still retain all membership benefits you have been entitled to. 

Why become a Chartered Member of CIOB?

Achieving Chartered status means your skills, capabilities and experience can clearly be recognised by others. It becomes easier to get involved in projects, and it will help you win tenders that make a big difference to your career.

Progressing to Chartered Membership enhances your membership in several ways:

  • It benchmarks your skills against other Chartered Professions
  • You can stand for Governance positions, and have your say by gaining voting rights
  • Chartered Professionals are, on average, £152,000 better off throughout their careers
  • Studies show that your employability will see a 9% increase as a Chartered Professional

My employee holds ACIOB or ICIOB. What does this mean?

Associate membership (ACIOB) was often awarded to those in a management position for a couple of years with an academic qualification comparable to a HNC or other Level 4 qualification.

The Incorporated (ICIOB) grade was one step above Associate and was intended for experienced managers with the equivalent of a foundation degree, HND or Level 5 qualification.
