Undergraduate Curricula, Graduate Curricula, Traditional Degree Areas, Other Engineering Specializations
As of 1997, 315 institutions housed 1,516 accredited engineering programs within the United States. To receive accreditation for their engineering programs, university departments comply with the standards established by the Accreditation Board of Engineering and Technology (ABET). ABET is an organization that consists of twenty-six professional engineering societies and six other affiliating professional organizations. The twenty-five accredited engineering specializations in the United States include the following: aerospace engineering, agricultural engineering, bio-engineering, ceramic engineering, chemical engineering, civil engineering, computer engineering, construction engineering, electrical engineering, engineering management, engineering mechanics, environmental engineering, geological engineering, industrial engineering, manufacturing engineering, materials engineering, mechanical engineering, metallurgical engineering, mining engineering, naval architecture and marine engineering, nuclear engineering, ocean engineering, petroleum engineering, survey engineering, and nontraditional programs.
Despite the existence of an accreditation board, however, not all engineering schools and engineering programs within the United States are accredited. Therefore, prospective students are responsible for investigating the accreditation status of the department to which they apply. Accredited degrees are especially significant for undergraduate students who wish to pursue advanced degrees in engineering.
In addition to investigating the accreditation status of their proposed schools, engineering students must decide where they will pursue their engineering degrees. Engineering programs within research universities target both undergraduate and graduate engineering scholars. These departments are usually large and sometimes have undergraduate classes that are taught by graduate students pursuing a degree in the department. Schools with a majority of students whose primary area of study is engineering are often called institutes of technology. State universities house departments that usually produce the greatest number of engineers in the country because of the increased affordability of an engineering education at these schools and because of the larger number of students who enroll in state universities.
The curricula of undergraduate engineering programs may be completed within four years, although most engineering students take longer to complete their bachelor of science (B.S.) degree requirements. Typically, engineering students begin classes within their major during their sophomore year. By their junior year, students continue to fulfill their major's requirements with an increased emphasis on laboratory assignments. Within their senior year design courses, students are expected to use their cumulative knowledge of engineering, writing, and the humanities to solve a problem within their major area of study.
General undergraduate engineering requirements as established by ABET mandate that each student's curriculum includes mathematics, engineering topics, and humanities. Because the entering level of mathematics varies depending upon a student's beginning knowledge of the subject, the amount of time required to complete mathematics requirements also varies. Once engineering students meet necessary mathematics prerequisites, they are required to complete differential and integral calculus, differential equations, and one or more upper-level mathematics classes successfully.
Students are also required to complete general engineering courses on topics such as mechanics, thermodynamics, electrical and engineering circuits, transport phenomena, and computer science. Students fulfill the third requirement, humanities, they complete classes in subjects such as literature, art, foreign languages, and social sciences.
In addition to the three requirements established by ABET, all engineering students must take core classes in physics and chemistry, as well as free and technical electives. Within the undergraduate engineering curriculum, electives may be classified as either free electives or technical electives. Free electives are classes that students can take in any department of the university if they meet prerequisites for that class. Technical electives are electives that are a part of a student's major course of study. In the process of fulfilling technical electives and major requirements, students might also fulfill minor area requirements and therefore obtain engineering knowledge across disciplines.
Compared to the undergraduate engineering program, graduate study in engineering is more research intensive and flexible. In addition, the class requirements for graduate students are not as restrictive as the requirements for the undergraduate degree. Because of the variation of specialization in graduate engineering courses across the United States, defining a standard program of study for a particular discipline is difficult. By working closely with an adviser in their major, however, students may create a program of study with classes that not only interest them but also will prepare them to specialize in an area within their field of engineering.
Admission requirements to U.S. graduate engineering departments vary. Students are generally admitted to a program, however, if they have a "B" average in their undergraduate classes. Once admitted into a program, students typically fulfill course requirements within one to two years, depending upon any deficiencies that a student might have prior to beginning a program of study.
Upon completion of a graduate engineering program, students may obtain one of two types of master's degrees within their discipline, the master of science (M.S.) or the master of engineering (M.Eng.). The master of science degree requires the writing of a thesis, whereas the master of engineering degree requires the completion of course work. Two types of degrees also exist for doctoral students of engineering, the doctor of philosophy (Ph.D.) and the doctor of science (Sc.D.). The doctor of philosophy degree is more research oriented than the doctor of science degree and obtaining it requires a student to write and defend a dissertation successfully. A student can typically complete an engineering doctorate two to four years after the completion of the master's degree.
Traditional Degree Areas
The five largest and most traditional areas of engineering study in United States colleges and universities are chemical, civil, electrical, industrial, and mechanical engineering. Within the United States, approximately 260 departments award these five degrees. Over the years, twenty-five specializations have emerged from the basic fields, and in 2001, eighty-five subdivisions of these fields existed in colleges across the United States. Following are descriptions of the five major types of engineering degrees.
Chemical engineering is a field of engineering that combines the knowledge of chemistry and engineering. Unlike chemists, however, chemical engineers develop new materials and design processes for manufacturing. In an effort to design these processes, chemical engineers must stay abreast of technological advancement in society. Specific curricula requirements for undergraduate chemical engineering students include engineering science, engineering design, communications, and basic life sciences. In addition to general engineering requirements, chemical engineering students are expected to earn course credit for classes in materials science and material and energy balances. Engineering design courses include engineering economics, design of chemical reactors, heating and cooling apparatus, and piping. In addition, chemical engineering students are required to understand computer programming languages and complete a technical writing class.
Civil engineers utilize their knowledge of structural processes in a variety of ways. They often oversee the development of facilities such as buildings and bridges, in addition to the construction of highways, water resource facilities, and environmental projects. Specific course requirements for civil engineering undergraduates include classes in engineering and scientific programming, soil mechanics, engineering geology, strength of materials, analysis of determinate and indeterminate structures, hydraulics, highway geometrics, and surveying. A sample topic within a civil engineering design course might include an investigation of the design of steel and concrete structures.
Electrical engineers design and develop various types of electrical processes. Examples of their contributions include computer chips and systems, radio and television equipment, and power generation and control systems. Specific courses for electrical engineering students include classes in logic, set theory, algorithms, probability and statistics, numerical methods and analysis, and operating systems. Subdivisions of electrical engineering include power generation, control systems, communications, or electronics.
Industrial engineers contribute to the successful integration of processes and people. They look at the broad picture of engineering in an effort to maximize the benefits of a system. Additional courses for industrial engineering students include engineering economics, organizational development, computer simulation, statistical quality control, human factors engineering, and system evaluation. Other suggested classes include biology and psychology. Finally, mechanical engineers examine how mechanical work and various types of energy combine in an effort to design materials and processes for use. In addition to core engineering classes, mechanical engineers may complete several courses in electrical and materials engineering.
Other Engineering Specializations
In addition to the traditional engineering fields, there are several branches of engineering and areas of specialization. Aerospace engineering is the study of aspects of aeronautics and space. Aerospace engineers may select from several divisions of study within their field. They are encouraged, however, to also obtain knowledge about mass transportation, environmental pollution, and medical science within their curricula.
Agricultural engineering is a field of engineering that is most closely related to the environment. Agricultural engineers are concerned about the conservation of natural resources and are required to build new tools that will aid the production and distribution of food and fibers.
Biomedical engineering applies the principles of anatomy and engineering to biological systems. With their knowledge of these systems, biomedical engineers may assist the health care industry through the design and maintenance of medical systems and equipment. In addition, biomedical engineering students often use their engineering training as a foundation for medical school.
Computer engineering mandates that students become knowledgeable in the areas of computer information systems, computer science, computer hardware, and information science. In many schools, computer and electrical engineering is a dual specialization. Next, environmental engineering improves the quality of life through the preservation of the environment. Environmental engineers are interested in reducing pollution, encouraging hygiene, and reducing waste and toxins found in air and water.
Nuclear engineering closely resembles the science of physics, because nuclear engineers study matter, including protons, neutrons, and electrons. They primarily investigate the nature of inanimate objects. Metallurgical engineers study metals and investigate ways to improve the characteristics of metal for society's use. Three areas of specialization within this field include process metallurgy, physical metallurgy, and materials science.
