Is there a study guide available for the AP O+M?
Director of LEED Support, Green Building Certification Institute
Thank you for your interest in the LEED O+M exam. Unfortunately, at this time, we do not have a LEED O+M v4 study guide available for purchase. In the meantime, it may be helpful to consult the LEED AP O+M candidate handbook which lists the specific references used to write the exam questions:

Hi there, I just passed my Leed Associate exam a few weeks back. I took it before the June 15th deadline. Now i want to take the O+M exam and was wondering about the questions On the new Leed v4 O+M. Will the 100 questions be about Leed v4 O+M only or will it contain questions from the Newer version of Leed v4 associate test. What should i expect ?
LEED Specialist, U.S. Green Building Council
Please see the Candidate Handbook for the O+M exam, under the Exam Specifications heading ( for information regarding the exam content.

Hi there, I am preparing for the AP O+M exam and was trying to schedule the exam. Two years ago I've passed the Green Associate exam, That time I had to use the resource to register for an exam and prepare proper documentation that I'm eligible to take the exam. Now, I'm trying to register for the AP speciality exam only. My question is, do I have to pay for the exam prior to checking if I'm able to take the exam? Or Green Associate do not have to demonstrate experience and knowledge? One more thing, we get the 'eligibility ID' right after payment, to schedule the exam? I couldn't find those info in candidate handbook. I will appreciate answer. Thank you.
LEED Specialist, U.S. Green Building Council
The experience requirement has been removed, so everyone is eligible for the exams. The Eligibility ID will be provided at the end of your exam sign-up process on You can then use this ID to schedule your exam with Prometric.
Hi there, I see the candidate handbook uploaded but I'm wondering if the O & M study guide is available; I know I had a USGBC study guide for the BD+C 2009 exam and I'm looking for the equivalent resource for EBOM v4.
LEED Specialist, U.S. Green Building Council
Hi Allison - the study guide is not yet available, but is expected to be available in the fall. For more information on what is currently available, please see the study tips article, available here:
