FAQ What is LEED? LEED stands for Leadership in Energy and Environmental Design. This is a rating system developed by the United States Green Building Council to encourage sustainable design, construction and building operation practices. Points are earned that relate to sustainability, and levels are achieved and awarded to projects that earn the required number of points.
What is the LEED AP exam? This is an exam that will test your knowledge of one of the following rating systems: LEED NC , LEED CI or LEED EB.
What do AP, NC, CI, EB, and CS stand for? AP = Accredited Professional, the title you'll earn once you have passed the LEED AP exam.
What do I need to do in order to prepare for the exam? See the section on “Tips and Tricks” for this information.
Do you need to take all three exams to earn a LEED AP title? No, any one of the three will give you that status.
How is the exam scored? This is taken from the USGBC Professional Accreditation Handbook: “Examination raw scores are converted to a scaled score that ranges from a low of 125 to a high of 200 with a passing score set to 170. The scaled score is reported in the score report that received at the test site following completion of your exam. Note that the scaled score is neither the number of items correct nor percentage correct. Raw scores are converted to scaled score much like the conversion of height from inches to centimeters. USGBC reports scaled scores so that candidates know that a passing score of 170 is required to pass on each exam. In this way, confusion about what is required to become a LEED AP is avoided.” This seems a little cryptic, but here is the interpretation by LEEDsource: Point scale of 125 to 200 = 75 points available. 80 questions means each questions is worth (75/80) .9375 points. Minimum 45 points required to pass (125 + 45 = 170). 48 questions must be answered correctly to pass, or 60%. Another speculation is that 5 questions are dropped, possibly at random, leaving 75 questions that count for 1 point each. This means: Point scale of 125 to 200 = 75 points available. Minimum 45 points required to pass (125 + 45 = 170). In order to guarantee a pass 50 questions must be answered correctly, in case the 5 questions that are dropped are amongst the correctly answered questions. 50 / 80 = 62.5% LEEDsource recommends that you strive to achieve at least 75% on any practice or mock exams.
