Engineering Technology

Program Details

The Engineering Technology program, accredited by the Association of Technology Management and Applied Engineering (ATMAE), provides an up-to-date and challenging program in response to continuously changing and sophisticated technology and an increasingly competitive global marketplace. Students are prepared for careers in areas such as quality auditing, continuous improvement, production management, cost estimating, scheduling, and a variety of technical fields. Course content combines a unique blend of theory, principles, and concepts with know-how, practical application, and problem-solving skills which ensure that students are prepared to work in an enterprise environment. Laboratories support contemporary design, prototyping, and production software, plus industrial equipment, including CNC machining centers and material testing devices. No prior experience with engineering technology principles or software is required upon enrollment.

Special Opportunities

A key component of the major is a required internship. Every student in his or her junior/senior year earns course credit for successfully applying knowledge while gaining invaluable on-the-job experience. By securing an internship in any approved major-related field, each student has the opportunity to enhance his or her skills in a professional work environment of particular interest. Many students report that the internship experience helps them focus their career goals and make vital industry contacts that benefit them upon graduation. Industry site supervisors continually report that the required internship is a vital link between education and the world of business, industry, and government service.

There are many ways to benefit from a baccalaureate degree in Engineering Technology (ET):

  • 91+% placement
  • Applications oriented (hands-on)
  • Small student-faculty ratio
  • Small class sizes
  • Diverse faculty
  • Certification opportunities
  • Higher salaries
  • Develop ability to work in teams
  • Required internship (industry experience)

Student Activities

Students enrolled in the Department of Engineering Technology are encouraged to become members of diverse groups and societies, including the Illinois State Academy of Sciences or the Society of Manufacturing Engineers. Students travel to, and participate in, competitions at regional/national conferences, attend field trips, and host professionals who provide insight into their selected fields.

Student Success

The mean GPA for undergraduate students at WIU is 3.15. The mean GPA for graduates in Engineering Technology is 3.057.
