More than 37,000 people have become LEED APs since US GREEN BUILDING COUNCIL launched the professional accreditation exam in 2001. LEED APs work in every sector of the building industry, and are recognized experts in green building practices and principles and the LEED Rating System.
USGBC offers the following exam tracks for earning the LEED AP credential:
LEED for New Construction, version 2.2

You do not need to pass more than one exam track in order to become a LEED Accredited Professional. All LEED APs are eligible to earn one point towards certification under ID/IU Credit 2 by serving as a principal participant on a project team regardless of which exam track was achieved.
