CBCI indicates success in the BCI Certification Examination but not membership of the BCI. Those people listed here have elected to be included on this register and may have progressed to membership of the BCI but CBCI is not a membership grade.

There are four professional grades of BCI Membership: Associate, Specialist, Member and Fellow. For professional membership, applicants must meet the BCI requirements in terms of knowledge combined with experience in order to be awarded AMBI, SBCI, MBCI or FBCI.

There are also two non-professional membership grades – Student and Affiliate. Neither of these confers the right to use any post-nominal designation.
