While the U.S. Green Building Council handles the development of the LEED Rating System and offers LEED-based education programs, the LEED Professional Accreditation program is independently administered under the Green Building Certification Institute to allow for balanced, objective management of the credential. GBCI manages all aspects of the LEED Professional Accreditation program including exam development, registration, and delivery. This separation into two organizational entities brings the credentialing program closer toward meeting standards for programmatic excellence put forth by ANSI/ISO/IEC 17024.
There are several versions of the exam which correspond to the various versions of the LEED system, including LEED-NC (New Construction and Major Renovation), LEED-EB (Existing Building) and LEED-CI (Commercial Interior). The exam is open to all individuals interested in the LEED green building rating system. A LEED AP is generally recognized as an expert in the field of sustainable design. The exam is formatted in a computerized multiple choice format with instant scoring after completion. Many study resources exist for exam candidates from the U.S. Green Building Council, USGBC chapters and other authors. The exam costs $300 for employees of national member companies of the USGBC and $400 for everyone else. The LEED Accredited Professional Exam (LEED AP) consists of 80 questions, and is scored on a scale of 125 to 200, with a score of 170 required to pass.
