It's possible but not advisable. Since electronic transcripts are PDF files, it is possible to attach them to online applications.
We caution you in doing this because of the additional security (digital signature) and also because of the expiration date. We recommend you first check with the recipient before ordering an electronic transcript for job or scholarship applications to make sure it's safe to send.
If you do attach an electronic transcript to an application, make sure the recipient saves the username and password combination. It is required each time the transcript is accessed before it expires.
