Engineering Technologists and Engineers – What is the Difference?

This is the second in a series of articles about the licensure of engineering technologists in the U.S. The first article described the current status of licensure of technologists as professional engineers and indicated that some 17 jurisdictions do not provide a pathway for technologists to become licensed, while the balance of the jurisdictions do, generally requiring additional years of engineering experience, averaging about six years. Licensure as a professional engineer requires a technologist to pass both the FE and PE examinations, which address a technical engineering body of knowledge, and not necessarily an engineering technology body of knowledge. This article will describe the differences between educational accreditation criteria and typical curricula for engineers and technologists. This discussion of engineering technology is limited to accredited four-year degrees in engineering technology, not two-year technology degrees by which technicians are educated.

There is a huge difference in the number of graduates annually. Data presented on the American Society for Engineering Education Web site indicate that there were about 6,400 baccalaureate degrees awarded in 2012 in engineering technology in the U.S. This compares to over 88,000 baccalaureate degrees in engineering awarded in 2012, an all-time high.

Engineering and Engineering Technology Accreditation Criteria
ABET accreditation criteria are prescribed by means of “general criteria” that apply to all disciplines and “program criteria” that are established and apply to each specific discipline. For engineering, the accreditation criteria are those of the ABET Engineering Accreditation Commission (EAC), and, for engineering technology, the criteria for the ABET Engineering Technology Accreditation Commission (ETAC) apply. The differences between the general criteria are subtle but significant, summarized in the following fashion. These are examples; refer to the ABET criteria at the links above to fully understand the differences.

Engineering and Engineering Technology Curricula
According to data presented on the ASEE website, Purdue University graduates the greatest number of technologists in the US each year. Presented below is a very brief summary of the sample 2012-13 plan of study for electrical engineering, and for electrical engineering technology, from the Purdue University website. The major components of the typical curriculum are as follows:

Purdue University – 2012-13 Electrical Engineering Plan of Study
Math – Calculus I and II, multivariate calculus, differential equations, linear algebra and probabilistic methods
Science – Chemistry, Physics/Mechanics, Physics Elect/Magn Interactions, Science Elective
Engineering Science – Linear circuits I and II, introduction to electronics, electric and magnetic fields
Design – 10 design courses and electives

Purdue University – 2012-13 Electrical Engineering Technology Plan of Study
Math – Calculus for Technology I and II, Statistics
Science – General Physics I and II, electives
Technology and Design – 18 courses in various aspects of technology and design

The electrical engineering and electrical technology program curricula at Purdue clearly show the difference. The engineering program provides a substantially greater math background, more science, a background in engineering science and engineering design. The electrical technology program provides a much more basic background in math and science, without substantial engineering science, and with extensive technology and design content. Engineers generally are trained to analytically apply the theory and practical applications of math, science, and engineering science to design while engineering technologists are trained to apply technologies to design in what some have described as a hands-on fashion.

Both the accreditation criteria and the typical curricula cited above prescribe very different “bodies of knowledge” imparted in engineering and engineering technology education. Engineering education includes a significantly more extensive background in both mathematics and the sciences, which leads to a foundational background in engineering science. Design capability is then built on that math/science/engineering science foundation. Engineering technologists develop a basic understanding of math and science, and learn applied science and engineering built on a different foundation.

It is interesting to note that the ABET program criteria for civil engineering technology states as an objective that baccalaureate degree programs prepare graduates “to analyze and design systems, specify project methods and materials, perform cost estimates and analyses and manage technical activities in support of civil engineering projects.” In our licensure system in the U.S., each of those activities, when potentially impacting public health, safety, and welfare, need to be under the responsible charge of a licensed professional engineer, and those designs and specifications need to be stamped by a professional engineer. In one-third of the states, there is no pathway for technologists to be licensed as professional engineers. In the other two-thirds of states, technologists are required to pass the Fundamentals of EngineeringExamination, which assesses the engineering body of knowledge, and not the very different engineering technology body of knowledge, and additional years of engineering experience are required for technologists in many states. Those who review FE exam institution reports provided to technology programs indicate that the pass rate for engineering technologists on the FE exam is typically substantially lower on a national basis than the national pass rate for EAC-accredited engineering program graduates. This would be expected because the typical engineering technology education does not cover a fair amount of the FE exam content.

This begs two questions. First, is the current system appropriate? In order to become licensed, technologists are required to pass a fundamentals examination with content that was not included in their education in many technology programs. Those engineering technologists who can pass the two examinations work as professional engineers, and those who cannot, likely work as technicians. And secondly, is this a problem? I don’t know the answer to this second question. Is it a problem for technologists or employers that technologists can’t get licensed as PEs in one-third of states, and is passing the FE examination by technologists too formidable a hurdle in the other two-thirds of states? These two-thirds of states have determined that those technologists who do pass both exams, perhaps with a few more years of engineering experience for good measure, are qualified to practice as professional engineers. Is that a problem?

A subsequent article on this topic will address what is being done in some other countries with respect to licensure of technologists separate from licensure of engineers. Should we continue to license some engineering technologists as professional engineers, or does the licensure of engineering technologists merit consideration? The more I consider this topic, the more ambivalent I have come as to whether there is a sufficient problem here to consider change. Is there a problem?

I have a bachelor's degree in Civil Engineering Technology. During my senior year, I found out that I would be unable to be licensed in certain states. This was news to me. I thought that if I could get licensed in my current state, then I could get licensed anywhere. Myself and about 65% of us passed the FE exam. So I was faced with a decision...Do I go back to school somewhere else to get a BSCE? or Do I go to work wherever I can find a job and just hope that I will be okay in the long run? or Do I go to graduate school to get a Master's degree in Civil Engineering? I realized that it would be very hard to progress in my career if I would not be able to become a licensed PE in whatever state I work in.
I chose to seek a master's degree in Engineering. Some may disagree with my  reasoning but these are  some of my thoughts about it. I truely felt that my undergraduate coursework covered the majority of what most BSCE programs cover. The classes might not have been quite as rigorous, but I felt as though we covered 95% of the topics/theory. The primary difference was math as we did not have to go through Diff eq. However we used alot of calculus in our classes. Because of this I felt as though I would not be progressing if I went to get a BSCE. Also, I felt that having a master's in a specialized field (water resources engineering) would open up doors for a career path where a PE license would not be an absolute requirement (i.e. Hydrologist, Water Management, etc.). I was accepted to a respected Civil Engineering program (my job experience and high GPA really helped). I was required to take the additional math through Diff Eq. I did that, and it was difficult but not a problem...I actually enjoyed the extra math courses. My undergraduate preparation in fluid mechanics, hydrology, hydraulics, soil mechanics helped me transition quite well to graduate level hydrology/hydraulics courses that included advanced theory, numerical modeling, etc. There were a few topics where I had to spend a little extra time, but for the most part I did well.
So what is my point? Now I am working for an organization where I analyze and solve large water resources related problems. I work around engineers who have masters and PhD's from highly respected programs all over the country. I have been here about a year and a half and I hit the ground running and have been able to learn and progress at a fast pace. I am planning to take the PE in a state that will allow me to in another year or so.
Having gone through all of this, I feel as though I am fully competent EIT/EI who has the background and capability to do my job in a way that keeps people safe. This is a result of all of my experience and combined education. If I could do it over again I would have pursued a BSCE from day 1. I think my Eng Tech program was unique and probably built more like an engineering program. As a young person entering college, I had no clue the difference between ABET/TAC and EAC. I just enrolled in the nearest school and chose to major in something "cool."
It is still hard to know that I may not be able to pursue certain jobs in certain states due to my education, however I have commited myself to becoming very very good in my field and I believe that I will be able to have a successful career in something I love to do.
So to answer your question in the article...If I were making the rules, I would allow Eng Tech graduates to pursue licensure, however I would say they need to demonstrate their ability through 1. Pass FE 2. Pass PE 3. Masters degree in Engineering from program that offers ABET/EAC undergrad (similar to 2020 plan) 4. 6 years of experience under a PE (instead of 4 years)
If someone can demonstrate all of those things, I would say they have proved they know what they need to know. Also, I have learned quickly that if you don't your stuff in this industry that you will be quickly weeded out.
Those are my thoughts as of right now. Thanks for the article.
