Here is another O+M Exam prep from USGBC Education partner GBRI. It comes with project experience portion that would be tested on the LEED v4 exam (LEED Project experience is not a requirement anymore for exam eligibility but per GBCI Candidate handbook, project experience competency will be tested on your exam). The exam prep also include FREE access to LEED Green Associate Materials -

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.
