Sample LEED AP O+M Readiness practice questions
These sample items mirror the domains in the timed LEED AP O+M Readiness mock. Correct answers and explanations unlock inside the practice session.
Sample 1
A broken irrigation lateral on a corporate campus ran for three weeks before anyone noticed, even though the irrigation zone had its own submeter. That submeter was read by hand once a month. Which change would most shorten the time to detect the next failure?
- A. Replace the clock timer with a weather-based irrigation controller that adjusts run times to local conditions
- B. Keep monthly manual reads but add a quarterly reconciliation of the submeter against the utility's water bills
- C. Log the submeter at short intervals to the building system and alert on flow outside scheduled watering windows
- D. Add a second whole-building meter so the campus total can be cross-checked against the utility's monthly invoices
Sample 2
A property manager is replacing a pest control vendor whose contract was built on routine scheduled spraying. Which selection criterion best aligns the new contract with Integrated Pest Management?
- A. The vendor offering the lowest monthly fee for unlimited scheduled pesticide applications in all areas
- B. A vendor whose technicians each hold state pesticide applicator licenses for every product they apply
- C. A vendor that guarantees a pest-free building by treating every floor on a fixed quarterly cycle
- D. A vendor with a third-party IPM service certification, such as GreenPro, and documented monitoring
Sample 3
Service logs show a technician has topped off the same split system with refrigerant four times in ten months, each time noting 'low charge.' What should the refrigerant management program require?
- A. Continue topping off, as long as each recharge is recorded accurately in the service log
- B. Switch the unit to annual service visits so it is topped off less frequently
- C. Remove the unit from the inventory, since chronic leakers distort the building's leak rate
- D. Locate and repair the leak, verify the repair, and track the unit for recurrence
Sample 4
An owner wants the LEED boundary for an existing office to stop at the building footprint, leaving out the surface parking lot and loading dock that occupants and deliveries rely on, because those areas would hurt site and transportation results. How should the LEED AP advise?
- A. Accept it, since O+M certification covers building systems and site areas are optional for existing buildings
- B. Accept it if the owner submits a CIR first, because boundary choices are approved on a case-by-case basis
- C. Shift the parking and dock into a separate LEED project so the office can certify on its footprint alone
- D. Reject it, because a reasonable boundary includes site areas that support normal building operations
Sample 5
A property manager compiles commute-mode responses from building occupants for Sustainable Transportation Performance. What does the resulting sustainable transportation rate express?
- A. The share of occupant trips made by walking, cycling, transit, and other low-carbon modes
- B. The number of parking spaces provided per 1,000 square feet of gross floor area
- C. The count of transit stops and bike lanes located within walking distance of the entrance
- D. The annual fuel use of owner-operated fleet vehicles divided by building occupancy

What changed in the current exam cycle

- O+M emphasizes performance periods, ongoing reporting, and existing-building operations rather than new-construction design credits.
- Energy and Atmosphere and Indoor Environmental Quality remain the heaviest specialty domains for O+M.
High-yield facts (commonly tested)
- Specialty exam: 100 MCQ in 2 hours; scaled pass 170/200.
- Active LEED Green Associate is required for the specialty-only registration path.
- Study operations performance periods, metering, retro-/monitoring-based commissioning, waste diversion, and IAQ operations — not BD+C design modeling alone.
- Primary v5 reference: LEED v5 Reference Guide for Operations and Maintenance (July 2026 edition); confirm the current handbook for your test date.
