The United States Green Building Council has developed the Leadership in Energy and Environmental Design Accredited Professional (LEED AP) to give special recognition to those who demonstrate exceptional knowledge and skill in an area of green building and construction. One of these exams is the LEED AP Homes exam.
The LEED AP Homes is divided into two parts, each of which is 100 multiple-choice questions and takes two hours. The entire exam takes about four hours and twenty minutes. Part one of the LEED AP Homes is identical to the Green Associate exam.
It covers the following subjects: synergistic opportunities and the LEED application process; project site factors; water management; project systems and energy impacts; acquisition, installation, and management of project materials; stakeholder involvement in innovation; and project surroundings and public outreach.
The second part of the LEED AP Homes exam, known as the Homes Specialty Exam, covers the following subjects: project site factors; water management; project systems and energy impacts; acquisition, installation, and management of project materials; improvements to the indoor environment; stakeholder involvement in innovation; and project surroundings and public outreach.
The scoring system for LEED AP exams is fairly simple. Raw scores (the number of questions answered correctly) are placed on a scale from 125 to 200. The minimum passing score is 170. The scaled score is reported immediately after the computer-based examination.
If you pass, you will only receive notification of this fact. If you fail, you will receive a detailed score report, so that you can determine the areas in which you need to improve your performance. You can take the LEED AP test up to three times during the one-year period in which your application is active. You only have to retake the sections of the AP exam which you failed; you will not be allowed to retake the part of the exam you passed with a view to getting a higher overall score.
