To be eligiblefor the LEED Green Associate credential, you must have previous experience supporting a project registered for LEED certification, working in a sustainable field of work, or attending an education program that addresses green building principles. Only one of these criteria is required to be met to demonstrate eligibility. The LEED Green Associate exam is a 2-hour exam. The LEED Green Associate exam is neither a prerequisite nor an eligibility requirement for the LEED AP or any other GBCI exam.
- 175. To be eligiblefor the LEED AP credential, you must have previous experience with a project registered for LEED certification within three years of your application submittal date. This work experience must be documented in the form of a letter of attestation from a supervisor, client, or project manager and must describe your involvement on the LEED Project as a consultant, contracted worker, member of the LEED project team, LEED Homes Provider, LEED Reviewer, LEED for Homes Green Rater, or staff member of a Certifying Body (CB). The LEED AP is a 4-hour exam comprised of two parts: the LEED Green Associate and LEED AP specialty exams. (If you are enrolling or currently hold an active LEED Green Associate or LEED AP credential, you are exempt from the first part.) If you wish to take the exam in two 2-hour sessions, you may first apply for and earn the LEED Green Associate and then apply for the LEED AP including demonstrating eligibility and paying the applicable fees.

Green Building: WashingtonBill Requires LEED Certification For Sales and Use Tax Deferral A bill was introduced in the Washington State Legislature yesterday that will require LEED certification for sales and use tax deferral on select construction projects. If this bill (SB 6598) becomes law, projects will have to achieve a certain level of LEED certification to qualify for deferral of sales and use tax on materials and other components of the work. The higher the project's LEED certification, the greater the amount of sales and use tax that's deferred. This chart identifies the percentage of sales and use tax each level of certification will deliver: LEED Certification Level Percentage of Sales and Use Tax Deferred Platinum 100% Gold 75% Silver 50% Less Than Silver 25%
