    I realize the first post to this thread has probably been certified a long time ago, but I help write questions for the NEBB exams so I've got a bit of insight. I can't go into details of the exams, but I can confirm that the tests are now done through Kryterion testing sites, or paper tests at NEBB seminars. Candidates that review and understand the material in the recommended reading material will likely be fine. I couldn't share the pass percentage even if I knew, but I think it's safe to say most failures are the result of the candidate either not preparing or suffering from test anxiety.

    Brent you are correct I was certified a long time ago. I think the written test when I took it was appropriate to determine understanding of the fundamentals. I have stressed on this site many times the importance of knowing and thoroughly understanding the fundamentals. If you don't know the fundamentals and how they apply all you are is a hood holder and have no business having a certification. Some think the intent of the test is to limit the number of people that get certified. I don't think that is remotely true. I don't think the practical exam is necessary. There are so many DDC balance programs it is possible to test on one the candidate has never seen. I assume the practical includes balance of DDC controlled VAV'S. The control contractors only share the bare essentials with balancers and it takes a while to learn everything you need to know.
    I'm retired but am glad you posted and glad to hear the test has been improved.

    I've known some of the men who helped write the early exams, and while they were really knowledgeable, they would occasionally get the answers to their own questions wrong because they're human and there wasn't much of a review process. The gentlemen proctoring my practical exam is still involved in the business, so I'll be respectful, but I think it's fair to say that it could've been done better. Whether or not the testing format is better now is probably debatable, but without a doubt the questions are better reviewed and have clear answers.

    I think the practical exam is very difficult to structure. I only remember one of the questions on the written exam that didn't have a correct answer when I took it. The answer was as simple as it gets. Elevations were given on piping before and after a pump and they were looking for static head on the pump. It was a simple addition problem and a review before issuing the test would have almost certainly caught it. I was also certified in S&V. The annual test at one point got way above taking readings. The time it took to answer the questions got ridiculous. I wrote NEBB and told them that and warned that the tests were encouraging giving advise and we shouldn't be doing that. Surprisingly enough they agreed and modified the tests.

    One of the writers of the early exam presented me with a question that went something like the following, although in diagram rather than description: There's an open water tank that measures 10' diameter and 10' tall. The tank is filled with 8' of water. What's the pressure at the bottom of the tank?

    Of course, 8' seems like the obvious answer, but he calculated the volume of water, how much it weighed, then divided that by the area of the bottom of the tank and came up with answer that wasn't 8'. I mean, the math idea was right, just a mistake made in rounding or one of the steps due to over-complication. Anyway, it's part of the reason I was happy to volunteer with question writing.

    Thanks for that Brent. I was never able to figure out why the question I referred was on the test and even more wondered how come the answer was wrong. I would never have figured that out.
