The Green Building Certification Institute (GBCI) has announced that three of its LEED Professional Credentials have received American National Standards Institute (ANSI) accreditation under international standard ANSI/ISO/IEC 17024, Conformity Assessment: General Requirements for Bodies Operating Certification of Persons.

GBCI joins a group of 30 other personnel certification bodies in a range of industry sectors to achieve ANSI accreditation since the program’s inception in 2003. ANSI accreditation is designed to increase the integrity, confidence, and mobility of certified professionals.

Accreditation has been granted to the LEED Green Associate, LEED AP Operations+Maintenance, and LEED AP Homes credentials, the first of the LEED credentials to be introduced following the release of the LEED 2009 rating system. GBCI expects to submit the remainder of the LEED Professional Credential suite for accreditation later this year.
