Since September 2007, dossier services for Columbia students (also called "credentials services") have been provided through a partnership between the Center for Career Education and Interfolio, Inc., an on-line, confidential credentials file management service ("Interfolio").

Interfolio maintains individual files containing letters of recommendation and related materials for students and alumni of the Graduate School of Arts and Sciences; graduate students of the Fu Foundation School of Engineering and Applied Science; School of General Studies; School of the Arts; Graduate School of Architecture, Planning, and Preservation; and School of Continuing Education. Students and alumni of Columbia College and undergraduates of the Fu Foundation School of Engineering and Applied Science maintain their dossier files through their individual advising centers.

Interfolio forwards designated dossier files in connection with applications for opportunities in colleges, universities, independent schools, and industry. We recommend that individuals planning to apply for positions register on-line with Interfolio and open a dossier file at least 18 months prior to their anticipated availability for a position. The Center for Career Education supports users of Interfolio with dedicated personnel.
