SIIT students have many opportunities to participate in a variety of activities, both academic and extra-curricular, to develop self-discipline, self-responsibility, professional attitudes, and for relaxation. The SIIT Student Committee and other student clubs such as the Sports Club, Academic Club, Volunteer Club, and Createch Club organize a wide range of programs and activities throughout the year. Additionally, individual academic programs have student clubs which collaborate with faculty members in academic related activities. The student activities are supervised by academic advisors and the assistant director for student affairs.

SIIT provides a stimulating and international learning atmosphere to students by offering all courses, both lecture and laboratory, in English and taught by both foreign and Thai professors who have extensive overseas educational and work experience. The number of international students at SIIT is increasing due to SIIT's widely accepted reputation in quality educational programs and faculty members. Students are frequently given lectures on a variety of topics by visiting professors from the USA, UK, Japan, India, etc., which give them exposure to new and emerging subjects. Academic exchange programs with selected universities in Australia, Finland, France, Germany, Japan and UK have been established to provide qualified students with an excellent opportunity for studying abroad.

Graduates of SIIT receive a wide range of job offers due to their proficiency in English and their competency in technical knowledge.
