Should it be called "preparing" or "prepping" for the PE (Principles and Practice of Engineering) Exam?
If you've studied for the exam and spent hours and hours covering thousands of pages of material - it just might feel more like "prepping" for doomsday more than anything else. The required references for 2019 alone now cover 9 different books, 12 volumes and over 6,500 pages.
This week I'm covering a review of the 2018 exam and some updates to 2019 for the Fire Protection PE Exam.
Discouraging 2018 Results
The overall results from all 241 examinees came in December, and the results were not great.
Pass rates for first-time examinees fell to 56%, the lowest this decade. The pass rate for repeat takers also fell to 28%, the lowest rate since 2015. These results are published annually by NCEES.
4th Toughest Exam for First-Timers
We once again maintain a distinction for having one of the most difficult exams to pass. The 56% pass rate for first time examinees ranks 4th toughest of the 24 different PE disciplines, behind only software, civil (construction), and power systems.
The overall pass rate (first-time and repeat takers combined) isn't much better with fire protection having the 7th most difficult pass rate.
On a related note one of the adjacent fields where some people working in fire protection get their PE is mechanical and architectural. Architectural used to have an overall pass rate above 80%, but that appears to no longer be the case. The Mechanical PE on Thermal & Fluid Systems has an overall pass rate of 60%, higher than fire protection but not by a large degree.
Raw Cut Score about 70%
With the popularity of the Weekly Exam Series (a 20-week series of mini-exams for Fire Protection PE examinees), I've gathered significantly better analytics on the difficulty of the actual exam and how well studying translates to passing the exam.
We're now able to better estimate the raw cut score (the percentage of questions correct to pass the exam), and how the difficulty of the Weekly Exams compares to the actual exam.
From the 2018 exam, we've estimated an overall raw cut score of 69-70%.
MeyerFire User Pass Rates
The statistic I love and get asked about more than anything is what the pass rates are for people buying the PE Prep Guide and what the pass rates are for people doing the Weekly Exams.
In short, it is very difficult to calculate this value now that the Prep Guide has become so popular. Consider this - on the 2018 exam over 2 out of every 3 examinees had the 2018 edition in their hand when they took the exam. Many who didn't have the 2018 edition brought a copy of the 2017.
In concept, if nearly everyone has a copy of the book on the actual exam, then it becomes more of a prerequisite to taking the exam than it does a boost only to the person using it. Where I have found differentiation, though, is between examinees who get a copy, study early, and study thoroughly. Somewhat obviously - the best prepared tend to do better on the actual exam.
As for pass rates of the Weekly Exam - I'm trying hard to get those exact values. If you used the Weekly Exam Series in 2018, I would be very grateful to hear from you and how the test went.

Changes to the 2019 PE Exam
Once again the exam writers can't help but make tweaks between each edition of the PE Exam. While published articles as old as five years ago suggested a narrowing of required references down to just the NFPA and SFPE handbooks, the actual exam references have done anything but condense.
For 2019, there's a few notable changes from the 2018 Exam (as published by SFPE):
Here's the year to year changes, with edition, additions or subtracted changes highlighted.
The 2019 PE Prep Guide Release
Fortunately this year, SFPE released the required references earlier than in years past. As a result the 2019 PE Prep Guide, which usually would ship in June, will ship earlier. At this time I'm estimating a mid-may shipment of these editions for anyone who pre-orders a copy. Of course if you'd rather get a copy in your hands now, we still have the 2018 edition available.
Weekly Exam Prep Series
Back for a third year the Weekly Exam Prep Series will kick off June 3rd. If you're looking to get as much regular practice as is available anywhere in a fun exam-simulated pace, then this is for you. See where you rank and get access to over 400 questions with the Weekly Exams. Learn more about the Weekly Exam Prep Series here.
2019 vs. 2020 Exam
Big changes are ahead for the 2020 exam. Not only will the Fire Protection PE Exam transition to a computer-based exam, but the legacy of bringing in volumes and volumes of references will go away as well. As we understand it today, there will be a single, condensed reference book with formulas and charts that can be used on the exam - and that's it. It'll be a different delivery, different problem types, and a different reference.
It'll be a big change and without a doubt make 2020 examinees feel like guinea pigs in the sense of trying out something new to everyone involved (examinees, the exam writers, and prep material producers). That could be intimidating or could be an opportunity depending upon how you look at it.

I'm working on a project and need your very brief help. The link below has a four quick questions that take only 30 seconds to answer. It'll be a huge help for me on this project and in improving the site going forward.
If you already completed this from the post from Monday's Daily Forum post, thank you!! There's no need to fill it out again. I cannot tell you how thankful I am for the feedback and input thus far.
As a thank you for completing the survey I'm doing a drawing for a 1-Year Toolkit Subscription and a Free Copy of the 2018 PE Prep Guide (it's great as a reference book). This drawing is free and no purchase is required. Answer the four questions here:
Looking for an opportunity to turn a basic concept into a controversial one on a project? Great! This week I'm exploring the quick-response remote area reduction that's provided in NFPA 13.
Suppress Early, Suppress Less
The concept behind reducing the calculated hydraulically remote area in a fire sprinkler system is entirely based on fighting a smaller fire earlier in the development of the fire.
There's a handful of factors that contribute to the timing of sprinkler response (a good future discussion), which include the thermal sensitivity, sprinkler temperature rating, distance of sprinklers relative to the ceiling, sprinkler spacing, ceiling height, and dynamics of the fire itself.
The reduction in the hydraulically remote area is based upon comparative tests of quick-response against standard-response spray sprinklers. According to the NFPA 13 handbook, the tests demonstrated that the earlier the water is applied to the fire, the smaller the fire and ultimately the less number of sprinklers needed to activate.
Not Universally Accepted
While the remote area reduction has been included in NFPA 13 for years, it's not universally accepted. Many engineer specifications don't allow the reduction, and design standards for major organizations such as the Department of Defense (UFC 3-600-01) don't permit it either.
Why not accept the remote area reduction, if NFPA 13 includes it? Like other elements in hydraulic design for fire sprinkler systems, not using the remote area reduction provides an additional safety factor to the system.
Additionally, since the quantity of sprinklers relates to the quantity of water flowing in the system, main sizes are directly impacted by using or not using the quick response area reduction. Building owners may opt to not want to reduce the remote area to preserve reasonable (larger) main sizes and give themselves flexibility on building modifications and sprinkler system changes in the future.

This quick calculator is in part a checklist of prerequisites to reduce the remote area on a fire sprinkler system, in part a method of showing your work, and in part a quick calculator on determining your final remote area size. Don't see it below? Give it a try here.

A little earlier than this time last year I wrote an article covering how NFPA 13 addresses sprinkler protection underneath canopies, overhangs, and exterior projections on buildings. It ended up as one of my favorites and I've had good feedback on it as well.
With the big changes in re-organization to the 2019 Edition of NFPA 13, it is only appropriate to make a few updates to the flowchart and get it in your hands so you can do what you do best.
Here's a link to the original article in full. If you haven't read it, it might be worth a few minutes here:
Sprinkler protection for canopies & overhangs are an important part of the overall protection scheme for a building.
