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:
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.

I have not had experience working in a building or project registered in GBCI,I want to see am i eligible to register for LEED O+M Exam?
Digital Marketing Manager, U.S. Green Building Council
Hi Mostafa, proof of project experience is not a requirement to register for the LEED AP O+M exam. However, LEED project experience competency is assessed within the exam.
Facility and Operations Manager, UUSC
Can you please tell me a little more about taking the exam itself. For instance, is it a moderated exam? Are reference materials allowed? Are all questions multiple choice? And one of the reference links above is about certification fees; it isn't intended that people memorize values/rates/etc from the charts is it? thank you.
Digital Marketing Manager, U.S. Green Building Council
Hi Ethan, the Candidate Handbook is a great resource to find answers for your questions. In the meantime, here are some answers: 1) The exam is on a computer, so it's not moderated. 2) Reference materials are not allowed. 3) All all questions are multiple choice. 4) You should be familiar with the certification fees. Good luck!
Sr. Marketing Manager, Veritiv
The first 2 links go to the BD+C candidate handbook, not the O+M handbook.
