Earl J. Martin, Jr., an instrument technician, founded ITI in 1973. He developed the teaching philosophy and personal interest in the student, which are still the guiding principles of ITI today. ITI received accreditation by the Accrediting Commission of the National Association of Trade and Technical Schools, now the Accrediting Commission of Career Schools and Colleges in 1981. ITI began offering classes at its current facilities in 1979. Since then, courses have been added to the curriculum to widen the scope of the students and to more directly serve the needs of the business and industrial community.
ITI was formed to fit the needs of the businesses located in the Louisiana and Gulf Coast region. The objective of ITI remains the same as when it was founded: to train personnel to meet the job requirements of a progressive technological age. In its more than forty years of operation, ITI has believed in that objective and it shows with ITI graduates being placed nationwide as they go forth to meet the rising demands for trained technicians.
