In addition to completing the online employment profile, you may be asked to electronically attach additional material; such as: a cover letter, vita, resume, or responses to specific position-related essay questions.  You may also be asked to provide the names, phone numbers and addresses of professional references.  Supporting documents may be submitted with your application in electronic formats (doc, rtf, PDF, and txt).  Attached files should not be larger than 5 MB.  If possible, it is best to convert large documents into PDF files before uploading.  In some very specific circumstances, you may be requested to send additional materials directly to the hiring department.  Please review the requested application materials noted on each job posting to ensure that your application is complete.
