LEED GA Passing Score: What Is It?


Evan asks: What are the percentiles for LEED Green Associate scores? Where along the curve is the 170 supposed to be? I've read some things about GBCI wanting 70% or 80% of the people to fail, but does this apply to the GA test too?


Hi Evan, thank you for your question.

What is the Passing Score for the GA?

The Green Associate exam is composed of 100 multiple choice questions, which you must answer in a 2-hour timed session.

There are many versions of the exam. This means that there is no set breakdown of how many questions will be asked about each topic covered. Also, questions are at varying levels of difficulty.

As a result of this inherent variability, GBCI converts the raw exam score to a scaled score with the total number of points set at 200. The minimum score is a 125 and the minimum passing score is 170. This translates to a minimum passing score of 85%.

While GBCI does not reveal the exact methodology of scaling the scores, they did tell Tristan Roberts in a BuildingGreen interview that each question is multiplied by a difficulty coefficient. The more difficult the question, the more heavily it is weighted. This means that you are given more points for answering "difficult" questions correctly than "easy" questions.

Green Associate Practice Exam

Taking a practice exam is a great way to get a feel for the Green Associate exam format, scoring and material coverage. offers a free Green Associate practice test, which is a great place to start. also offers a variety of exam prep products that you can purchase, many of which contain practice exams.

To check how you’re doing on a practice exam, first you obviously have to check your answers. Then you calculate your percent correct.

Some practice exams that you can purchase will score the exam for you. In fact, some of them will attempt to replicate GBCI's scaled scoring.

I’ve heard that if you can get approximately 70% of your practice exam answers correct you should be able to pass the exam. Of course, since the minimum passing score on the actual exam is 85%, it would be even better to score 80-85% on the practice exams.

Does GBCI Want Me to Fail?

I'm curious as to where you read that GBCI wants 70-80% of LEED credential candidates to fail. I do not believe that this is true - though I'd be interested to see your source for this information.

Good luck, and I hope this helps!

RE: LEED GA passing score

Hi Haytham,

Yes, you should try to score at least 80-85% on any LEED GA practice exams that you take.

The passing score is 85% or 85 out of 100 questions correct.

Thanks again,
