GBCI works rigorously to maintain quality control on the project certification through global green building standards set and annually reviewed by our board members. GBCI credentialing programs are developed, delivered and maintained using best practices in test development. Since 2011, GBCI’s LEED credentialing programs have been ANSI-accredited under the ISO/IEC 17024:2012, Conformity assessment – General requirements for bodies operating certification of persons.

The quality and rigor of project certification is maintained through standards viewable in fully documented manuals available to the public. These standards are internationally renowned to follow best practices that allow GBCI to be transparent and open to feedback.

As an independent certifying and credentialing agency, GBCI has managed the certification of more than 3 billion square feet of real estate and the credentialing of nearly 190,000 green building professionals (a number that is almost equivalent to the number of architects in the U.S.).
