Since its founding, CIT has developed engineers able to thrive in every industry as well as successfully engendering an environment that advocates practical learning. To assist in achieving these two aims, industrial internships were incorporated into the curriculum as compulsory subjects over 40 years ago. With the cooperation of businesses and public offices working in the front lines of industry, over 1,300 students every year learn and acquire on-the-job skills in their given field.

The overall purpose of the internship program is to associate theory with practice and to allow the acquisition of skills that can be utilized when entering the workforce. As an initial step, students take subjects related to industrial technology. Thus, while acquiring knowledge and formulating their own career plans, students are able to prepare for an industrial internship. Industrial internships are conducted from late July to late September during a student's third year. Afterwards, at industrial-internship-report meetings held in late October, each student presents a report detailing his or her intern experience.

CIT defines industrial internships as special programs in which students receive practical training in business, professional organizations, or elsewhere. While receiving instructions at the internship location, students not only come into contact with the technologies that companies have pioneered on their own, but also are able to develop exchanges with many engineers and other workers active in their own major fields of study. This program is designed to produce engineers and researchers who understand both the theory and practice behind their fields.

Fields of study at CIT are extremely wide-ranging and inculcate techniques which students are able to utilize in a great variety of industrial or manufacturing environments. Students take the subjects falling within the category of industrial technology suits them best, this allowing them actively to pursue their career design after graduation. In this way, every student is able gradually to bring his or her own ideal image of an engineer into sharp focus.
