There are two entities involved with the LEED Accreditation process: USGBC and
Prometric Testing Centers.
You will register and pay for the exam at USGBC.org. Then they will provide a link
to the contracted testing company which is called Prometric. Prometric is a testing
organization that handles most major national and global certification exams and
they are the exclusive provider for USGBC's LEED examinations. There are Prometric
test centers in almost every major city - the easiest way to determine your closest
testing center is to visit maps.google.com and run a search for Prometric with your
zip code.
The LEED Green Associate and LEED AP exams are given on an on-demand basis, meaning
when you contact Prometric to schedule your exam, you book your exam date relative
to when they have availability on one of their computers. While the scheduling
process is extremely flexible, there is a strict limit of three (3) attempts per 1
year exam application period. The year starts from the date of your approved
application. In the event that an application expires, candidates will need to wait
90 days prior to resubmitting their application again.
