After every PE exam, I conduct an online survey with as many PE exam test takers that I can find. I primarily use my website, Engineering Pro Guides and Engineer Boards to find test takers to take the survey. The survey provides insight into an estimated passing score, how well test takers do based on experience and number of hours studied, which areas of the exam are difficult or easy. The raw results of the survey are shown on the link below. This link shows a summary of the results without any pivot chart analysis.
Number of Test Takers vs. Number of Survey Results
The survey is only as good as the number of test takers that take the survey. According to the NCEES website, there were 597 first time takers and 229 repeat takers, with a total of 826 Thermal & Fluids PE Exam test takers on October 2017. The survey had 46 responses or 5.6% of the total test takers. As you go through the results of the survey, please remember that only a small percentage of the test takers took the survey so you should be careful when assigning authority to the results of the survey.
Pass Rates on Survey vs. NCEES
The pass rates on the survey indicate that 89.1% people surveyed passed the exam and 10.9% failed the exam. The NCEES website indicates that 67% of first time test takers passed the exam and 37% of repeat test takers passed the exam. The overall pass rate was 58.7%.
Estimated Cut Score
The estimated cut score is determined by the highest fail score reported on the survey or on the Engineer Boards forum. The highest fail score was 45. This means that the possible passing score was 46. However, based on previous T&F surveys, the highest fail score reported was 53.
Pass Rates vs. Years of Experience
The following graph shows the relationship between passing/failing and the number of years of experience. Based on this graph, it looks like the number of passing test takers increases with years of experience. The number of failing test takers seems to decrease as the number of year experience is decreased. One theory is that with an increase of years of experience, the application type problems should become easier.
Pass Rates vs. Hours Studied
The following graph shows the relationship between passing/failing and the number of study hours. Based on this graph, the number of failing test takers seems to be independent of hours studied. The number of passing test takers seems to increase with hours studied. However, there seems to be a sweet spot at the 201 to 300 hours of studying. The number of passing test takers peaks at the 201 to 300 level and goes down after this point.
On the survey, each person was asked to choose three of their least confident topics. This question provides insight into which of the topics proves to be the most difficult for people. On the survey, test takers struggled with Cooling/Heating, Energy Recovery and Supportive Knowledge. The best insight to take from this information is that if you struggle in these areas, then you should not be too worried, because others struggled and still passed. However, if you want to set yourself apart from the other test takers then you should study these areas more diligently. Especially since these topics have a high amount of problems on the exam.
On the survey, each person was asked to choose three of their most confident topics. This question provides insight into which of the topics proves to be the easiest for people. On the survey, test takers did well in Thermodynamics and Fluid Mechanics. The best insight to take from this information is that if you struggle in these areas, then you SHOULD be worried, because people who passed did really well in these areas. You should study these areas more diligently. Especially since these topics have a high amount of problems on the exam.
