Choosing Alternatives to Transfer Credential Files

Current credential file holders who are no longer seeking employment, applying to graduate school, or wish to use a credential management service other than Interfolio have the following options:

  • Keep your inactive file at the Office of Career Counseling until you request that the OCC transfer your file to Interfolio. Inactive files will be destroyed after 5 years.
  • Close your Williams College Office of Career Counseling credential file and have the confidential contents shredded.
  • Transfer your file to a different institution. You may choose to have the Office of Career Counseling send your file to that institution’s credential file office. You will need to make your own arrangements to open a file at that institution.
