Students with disabilities are requested to present their Columbia accommodation letters to their instructor at the beginning of the semester so that accommodations can be arranged in a timely manner by the College, the department, or the faculty member as appropriate. Students with disabilities who do not have accommodation letters should visit the office of Services for Students with Disabilities in room 520 of the Congress building (312.344.8134/V or 312.360.0767/TTY). It is incumbent upon the students to know their responsibilities in this regard.
