Trinity College has been committed to engineering instruction for over one hundred years, offering civil and mechanical engineering courses as early as 1856. Today, Trinity is one of just a few highly-selective liberal arts colleges that offers three degree paths in engineering: an ABET-accredited Bachelor of Science degree, a Bachelor of Arts degree, and an M.S. in Electrical Engineering or Mechanical Engineering from the Rensselaer Polytechnic Institute through Rensselaer at Hartford after an additional year. These degrees prepare students for careers in industry and for further study in engineering graduate programs or post-graduate schools of law, medicine, and business.

Consonant with its intellectual environment, the Trinity engineering program requires substantial study in the traditional liberal arts, encouraging students to examine critically a broad range of scientific, humanistic, and technological problems. The engineering program encourages interdisciplinary ties to other science departments including biology, chemistry, computer science, neuroscience, and physics. Additionally, engineering students benefit greatly from the College's proximity to area educational, technological, and biomedical facilities, many of which offer internship opportunities, including Northeast Utilities, Pfizer, Texas Instruments, and United Technologies Corporation. All in all, engineering students at Trinity are prepared to understand and employ emerging technologies while benefiting from the development of leadership, civic responsibility, academic achievement, and life-long professional relationships among Trinity Engineering graduates.
