The LEED-AP-ID-C exam is the official USGBC exam behind USGBC LEED AP Interior Design + Construction (LEED AP ID+C) V4 — passing it earns you the USGBC LEED certification, a credential positioned at the Professional Speciality level. It is built for candidates who want to validate the skills measured by USGBC LEED AP Interior Design + Construction (LEED AP ID+C) V4. Depending on your track, the exam is also linked to the LEED Green Associate certification, so one pass can move you toward more than one USGBC credential.

The LEED-AP-ID-C exam presents 100 questions to be completed within 120 minutes. That pace leaves little room for second-guessing: read each question carefully on the first pass, flag the ones you want to revisit, and keep moving instead of stalling on a single item. Before exam day, run at least one full timed session in the TestSimulate desktop or online test engine with a comparable question load — a steady rhythm under the clock is a trainable skill, and it is often what separates a pass from a near miss.

To pass the LEED-AP-ID-C exam you need 170 out of 200, and the official registration fee is USD 350 (specialty only) / USD 550 (combined with Green Associate). Keep in mind that a failed attempt means paying that fee again in full — retakes are not discounted. Given the cost, self-test before you book: if you can score comfortably above the passing mark on two or three consecutive timed TestSimulate practice tests, your budget is far better spent on the exam itself than on a retake.

Must hold an active LEED Green Associate credential to take the specialty exam (or register for combined exam). Because USGBC revises its certification programs from time to time, treat this as a starting point rather than the final word. Confirm the current eligibility requirements on the official USGBC exam page before you register.
