Candidates who fail the LEED exam may retake the exams as many times as they like, however they are limited to a maximum of three times per year.

If a LEED AP candidate fails the Tier II, the LEED AP exam, but passes the Tier I, LEED Green Associate exam, they do not have to retake the LEED Green Associate exam again, they only have to retake the Tier II specialty exam for LEED AP that they failed.

The exams are multiple-choice and computer-based. The first part will be the core knowledge exam (taken by Tier I, LEED Green Associates) about green building and general knowledge about the LEED Rating System.

The second part, the LEED AP Tier II specialty exam, will be focused on the specialty area of the track you choose (i.e. LEED ID+C, LEED BD+C, LEED for Homes, etc.)
