TNI provides a Cooperative Education to all students. Students must participate in a co-op (four months) or an internship (two months) based on their academic majors. The objective is to educate students about practical work experience that directly relates to their academic majors and to assist them with defining a career path. During the practical training, specialized professionals supervise the students to enhance their knowledge and ensure their understanding of the work assignments. After training, many TNI students are offered full-time employment positions by their co-op/internship companies after graduation.
At present, over 600 companies have offerred more than 1,800 co-ops or internships job positions both in Thailand and overseas to TNI students. Partner universities, JTECS (Japan–Thailand Economic Cooperation Society), partner companies and benefactors, Thai and Japanese organizations, etc. sponsor certain co-op and internship programs.
