In 1975, the freshman and sophomore years consisted of interdisciplinary studies, and were organized in a modular format, with each course lasting a few weeks or months. All students, regardless of their previous education, were required to attend 24 interdisciplinary courses, some of which consisted of pre-recorded video tapes of "resident faculty" who were not on campus, while graduate students and teaching assistants played the video tapes and conducted discussions. Nobel Prize winner Melvin Calvin said that, even though he participated in a symposium on SCI, the use of his name in the MIU catalogue was "perilously close to false advertising". John Lewis, a professor at Massachusetts Institute of Technology (MIT) who created video-taped lectures for MIU, was supportive, saying that TM "unblocks the student's pathways to education". During this period, an open admissions policy was instituted, and transfer students were welcomed regardless of their academic history. In 1976, the accreditation evaluation team from the North Central Association of Colleges and Secondary Schools said the 19 senior and 20 assistant faculty were "creative in their vision for higher education and eminently qualified", and the university was granted "candidate for accreditation" status. At that time, faculty and administrators were paid "approximately the same base salary of $275 per month", with additional compensation "on a sliding scale for those with spouses and children", plus free housing in university dormitories. On campus, drugs and alcohol were "shunned" and a "strong sense of community" was said to pervade the institution.
