ExploreAbout this exam
The LEED AP Operations + Maintenance (LEED AP O+M) credential is a LEED professional specialty credential listed by the U.S. Green Building Council under "LEED AP with specialty." It is aimed at professionals whose work is the ongoing performance of existing buildings rather than design and construction: facilities and property managers, building engineers and operators, sustainability and energy managers, commissioning providers, and consultants who support existing-building certification and recertification. Because the credential sits on the operations side of LEED, preparation should center on how a building's measured performance is tracked, documented, and improved over time - energy and water benchmarking and metering, commissioning and audits, purchasing and waste streams, green cleaning and indoor air quality management, site and transportation performance, and light pollution. Expect heavy emphasis on performance periods, data quality, prerequisites, and recertification, and on the Arc platform as the tool through which operational data is submitted. Two practical cautions for anyone preparing now: the official LEED AP O+M credential pages at usgbc.org and gbci.org returned "Page not found" when checked on 2026-11-06, so confirm exam logistics and eligibility directly with USGBC/GBCI before booking; and LEED v5 is stated to be "Currently available for BD+C, ID+C, and O+M," so v5 O+M content may appear. Study the current LEED O+M rating system text, the credit library, and Arc guidance, and practice reading performance data rather than memorizing credit numbers.
What you'll study
About LEED AP O+M preparation
Which LEED rating system version should I study for the O+M exam?
Plan for LEED v5 O+M. USGBC's site states LEED v5 is "Currently available for BD+C, ID+C, and O+M," and v4.1 and v4 remain linked in the site navigation. Confirm the version your exam appointment targets with USGBC/GBCI, since the official credential page was unavailable when checked on 2026-11-06.
Where do I find the official exam format, fee, and passing score?
Only from USGBC and GBCI directly. The pages at usgbc.org/credentials/leed-ap-om and gbci.org/leed-ap-operations-maintenance both returned "Page not found" on 2026-11-06, so no item count, time limit, fee, or passing score could be verified. Use the USGBC Help Center or contact form before you register.
How hard is the LEED AP O+M exam compared with LEED Green Associate?
Expect it to demand more applied judgment. Green Associate tests vocabulary and credit intent; O+M tests whether you can run a performance period - choosing baselines, judging data completeness, handling exceptions, and documenting prerequisites. Candidates who only memorize credit thresholds usually struggle with data-interpretation and documentation-sequence items.
In what order should I study the O+M domains?
Start with rating system fundamentals and the Arc/performance-period documentation domain together, because every other topic depends on how data is collected and submitted. Then take energy, water, and materials and resources as a performance block, followed by indoor environmental quality and site/transportation. Finish with credential process and professional conduct, which is largely recall.
What trips up candidates most on O+M?
Three recurring failure modes: treating prerequisites as optional or interchangeable with credits; confusing design-phase documentation with ongoing operational tracking; and answering from memory of an older rating system version instead of the current text. A fourth is ignoring recertification and performance-period mechanics until late in study.
How much does the exam cost and how long is the appointment?
Not verified. Neither official source page was reachable on 2026-11-06, so fee and duration are unconfirmed here rather than guessed. Check the USGBC Help Center or your GBCI account for current pricing, member discounts, and appointment length before scheduling.
If I fail, how soon can I retake it?
The retake policy could not be confirmed from the retrieved sources, which returned "Page not found." Do not rely on secondhand figures. Confirm waiting periods and any re-registration fees with USGBC/GBCI support when you book, and budget for a possible second attempt in your study timeline.
Does the credential expire, and what keeps it active?
The validity period and renewal requirements were not verifiable from the retrieved pages, so treat any specific number you hear as unconfirmed. Ask USGBC/GBCI what continuing education and reporting cycle applies, and note that the site advises submitting an inquiry if you need help meeting a credential renewal deadline.
What is Arc and why does it matter for O+M?
The USGBC site describes "The Arc plaform" as supporting "exciting new certification capabilities alongside new resources" for LEED v5, and links project registration through an Arc address. For O+M candidates, expect questions on submitting operational performance data and on how measured performance, not design intent, drives certification.
Can I claim this page is official exam prep?
No. This is independent study material and is not affiliated with or endorsed by USGBC or GBCI. LEED and the credential names are their marks. Always cross-check logistics, rating system versions, and policy details against USGBC/GBCI primary sources before your exam appointment.
