The USGBC LEED AP Operations + Maintenance (exam code LEED-AP-O-M) is the exam you pass to earn the LEED AP Operations + Maintenance (LEED AP O+M) certification, a credential at the Professional level. It is also connected with related credentials such as LEED Green Associate. If you are mapping out a certification path with USGBC, this exam is a milestone worth planning around.

The LEED-AP-O-M exam includes 100 questions, and you have 120 minutes to complete them. With that many questions on the clock, pacing is part of the challenge: divide your time into rough blocks as you go, and flag the items that stall you so you can circle back at the end instead of burning minutes on a single question. A week or two before your exam date, sit at least one full timed session in the Lead2Passed test engine under the same time limit, so the pace feels familiar rather than frantic on the day.

You need 170 (scaled score out of 200) to pass the LEED-AP-O-M exam, and the official registration fee is USD 550 (non-member), USD 400 (USGBC member) - approximate. That fee is due again in full for every retake, which makes thorough preparation the cheaper investment by far. Before you book your seat, test yourself with the Lead2Passed practice questions until you are scoring comfortably above the passing mark on a consistent basis — it is the simplest way to avoid paying for the same exam twice.

No formal prerequisite required; LEED Green Associate credential is recommended before taking the exam.

Eligibility rules can be adjusted by USGBC over time, so before you register, confirm the current requirements on the official exam page: view the official LEED-AP-O-M exam information.
