ExploreAbout this exam
LEED AP Interior Design + Construction (LEED AP ID+C) is a professional credential for people who design, build and deliver commercial interiors. GBCI, which administers LEED credentials, describes a LEED professional credential as a way to demonstrate proficiency in today's sustainable design, construction and operations standards and to show knowledge and credibility to employers and clients. The specialty is aimed at interior designers, architects, contractors, facility professionals and sustainability consultants working on tenant fit-outs, renovations and interior projects. Candidates are expected to know the rating system category by category - LEED process, integrative strategies, location and transportation, sustainable sites, water efficiency, energy and atmosphere, materials and resources, indoor environmental quality, innovation, and project surroundings and public outreach - and to understand how credits are documented and verified on a real project. The rating system itself is in transition: USGBC states that LEED v5 is currently available for BD+C, ID+C and O+M, and GBCI states that registration closes on June 30, 2026, at 11:59 PM ET for most LEED v4 and LEED v4.1 commercial rating systems. Prepare using the LEED credit library, USGBC courses and events, and the official GBCI credentialing pages.
What you'll study
About LEED AP ID+C preparation
How many questions are on the LEED AP ID+C exam, and how long do I get?
The permitted source material does not state an item count or time limit for this exam, so none is given here. Item counts and timing are set by GBCI and are published on the credentialing pages at gbci.org; confirm the current figures there before you book a test appointment rather than relying on older study guides.
What score do I need to pass, and what does the exam cost?
Neither a passing score nor a fee is stated in the source material used for this page, so both are left unspecified. GBCI sets and publishes exam pricing and scoring on its credentialing pages. Check gbci.org, or submit an inquiry through the Help Center, for the figures in force on your test date.
Which LEED version does the exam cover?
USGBC states that LEED v5 is currently available for BD+C, ID+C and O+M, and GBCI states that registration closes on June 30, 2026, at 11:59 PM ET for most LEED v4 and LEED v4.1 commercial rating systems. The source does not publish an exam blueprint aligned to a specific version, so confirm credit-version scope with GBCI.
Do I need to earn LEED Green Associate before LEED AP ID+C?
GBCI lists LEED Green Associate and LEED AP with specialty as separate credentials, and the source material does not state a prerequisite relationship or an eligibility requirement for the AP specialty. Treat any prerequisite claim you see elsewhere as unverified and confirm eligibility directly with GBCI before scheduling.
How difficult is the exam, and how long should I study?
The source gives no difficulty rating or recommended study hours. Because the exam tests applied credit knowledge rather than definitions, most candidates need enough time to work through each credit category in the LEED credit library and practice mapping project documentation to credit requirements. Plan study time around your existing LEED experience.
What is the best study order?
Start with LEED process and integrative strategies, since they frame how credits are pursued and documented. Then work through the technical categories - location and transportation, sustainable sites, water efficiency, energy and atmosphere, materials and resources, and indoor environmental quality - and finish with innovation and project surroundings and public outreach. Use USGBC on-demand courses and live events to reinforce each category.
What are the most common ways candidates fail?
Typical failure modes are memorizing credit titles without understanding documentation requirements, ignoring prerequisites, and studying from outdated third-party summaries after a rating system transition. Given the LEED v5 rollout and the LEED v4/v4.1 registration close on June 30, 2026, at 11:59 PM ET, always study from the current LEED credit library.
Can I retake the exam if I fail, and how soon?
The source material does not describe a retake policy, waiting period or attempt limit for this credential, so no retake terms are stated here. Retake rules are administered by GBCI; review the credentialing pages at gbci.org or contact the Help Center for the current policy before you re-register.
Does the credential expire or need renewal?
GBCI references credential renewal deadlines and directs people facing one to submit an inquiry, which indicates renewal is required, but the source does not state a validity period or continuing education requirement. Confirm your specific renewal cycle and deadline through your GBCI account or the Help Center.
How should I prepare if my project is registering under LEED v4.1 rather than v5?
GBCI states registration closes on June 30, 2026, at 11:59 PM ET for most LEED v4 and LEED v4.1 commercial rating systems, so plan your registration date carefully. Study the credit library for the version your project will actually use, and note that USGBC states LEED v5 is currently available for BD+C, ID+C and O+M.
