I recently passed the US Green Building Council LEED AP O and M exam, and the Materials and Resources section felt very policy driven compared to design exams. Focusing on purchasing and waste stream tracking, plus the intent behind each credit, made the questions much more straightforward.

I recently passed the LEED AP O and M exam, and indoor environmental quality questions felt subtle since several answers sound reasonable until you read the intent carefully. I slowed down, looked for the operational angle, and eliminated options that were design focused rather than maintenance focused.

Materials and Resources questions often ask you to identify acceptable documentation for recycled content, regional materials, or EPDs and to determine whether a product qualifies under the credit requirements, those scenario questions can hinge on subtle definitions. Get comfortable with MR credit language, product category rules, chain of custody types, and waste diversion documentation, and I succeeded on the exam after targeted practice.

I managed to pass the LEED AP O plus M exam, and water efficiency was more detailed than I expected, especially around ongoing performance versus one time upgrades. What helped was tying each credit back to what you would actually measure and verify in a building.

Indoor Environmental Quality questions frequently test nuances like ventilation rate compliance, VOC source control, and sequence-of-operations for HVAC during occupant complaints, and I saw items that required distinguishing testing protocols from policy requirements. Study ASHRAE 62.1 ventilation concepts, common IEQ measurement thresholds, and the documentation that proves compliance, which helped me pass the exam.

Energy and Atmosphere can throw calculation and trade-off questions that ask you to compare baseline versus proposed energy use or pick the most impactful commissioning measure, I had to work through a couple of whole-building energy modeling style scenarios on the exam. Focus on ASHRAE 90.1 basics, commissioning fundamentals, and how on-site renewables affect credit thresholds, and I passed the exam and thanks Pass4Success for providing good collection of exam questions for preparation in short time.

Free US Green Building Council LEED-AP-O+M Exam Actual Questions

Note: Premium Questions for LEED-AP-O+M were last updated On Sep. 16, 2026 (see below)

Question #1

Which of the following prerequisites or credits has a minimum occupancy requirement?

Reveal Solution Hide Solution
Correct Answer: D

The Indoor Environmental Quality Prerequisite for Minimum Indoor Air Quality Performance has a minimum occupancy requirement to ensure that indoor air quality (IAQ) assessments accurately reflect the conditions experienced by building occupants. This prerequisite focuses on achieving acceptable IAQ within the building by meeting or exceeding local codes or ASHRAE standards, ensuring the health and well-being of the occupants. Reference: The LEED O+M Reference Guide's Indoor Environmental Quality section details the requirements for maintaining minimum IAQ performance, including the importance of considering occupancy levels in IAQ assessments.


Question #2

Which of the following is considered an ongoing purchase for the purpose of calculating Materials and Resources

Credit, Solid Waste Management - Ongoing?

Reveal Solution Hide Solution
Correct Answer: D

Toner cartridges are considered an ongoing purchase, as they are consumable items that are regularly replaced as part of the normal operation and maintenance of the building. The other options are not ongoing purchases, as they are durable goods that are not frequently replaced or disposed of.


LEED v4.1 O+M Guide, page 48

Solid waste management - ongoing, U.S. Green Building Council

Guide to the LEED AP Operations and Maintenance (O+M) Exam, page 157

Question #3

Discussing the project goals to help identify the credits and options that the team should attempt is an example of

Reveal Solution Hide Solution
Correct Answer: C

Developing the LEED Scorecard is the process of selecting the credits and options that align with the project goals and are feasible for the project team to achieve. The LEED Scorecard is a tool that helps track the progress and performance of the project against the LEED rating system requirements. Discussing the project goals is an important step in developing the LEED Scorecard, as it helps the team prioritize the credits and options that bring the most value to the project owner, environment, and community.


Question #4

The project team is attempting to achieve Option 1. Lighting Controls in Indoor Environmental Quality Credit, Interior Lighting. Which of the following is required documentation?

Reveal Solution Hide Solution
Correct Answer: A

The correct answer is A because a table of lighting controls installed is the required documentation for Option 1. Lighting Controls in Indoor Environmental Quality Credit, Interior Lighting, as stated in the LEED v4.1 O+M Reference Guide1. The table must include the type and location of each lighting control device, the controlled lighting power, and the percentage of lighting power controlled by each device1. The other options are incorrect because they are either not required or relevant for this option.


LEED v4.1 O+M Reference Guide, page 251

Guide to the LEED AP Operations and Maintenance (O+M) Exam, page 115

LEED v4 AP O+M Mock Exam, page 84

Question #5

A LEED AP is reviewing construction documents to identify the regularly occupied spaces on a project to ensure that floor area values are utilized consistently across credits. What aspects of each space should the LEED AP consider?

Reveal Solution Hide Solution
Correct Answer: C

When identifying regularly occupied spaces in a project, the LEED AP should consider the maximum number of intended occupants, whether standing or seated, in each space. This is important for ensuring consistency in floor area values across various credits, such as those related to indoor environmental quality or space utilization. The consideration of occupants helps in determining space functionality and occupancy patterns, which are critical for accurate LEED assessments.
