You must contact ETS to have your official TOEFL scores released to CASPA. Once you do, ETS electronically sends your scores directly to CASPA. Paper copies are not accepted.
To submit your official TOEFL scores to CASPA, go to http://www.ets.org/toefl and request your scores be sent to CASPA using code #3709. It takes approximately 10-12 business days from the date you make the request to post to your application.
Make sure that the name and date of birth on your application match that on your TOEFL exam; otherwise, your scores will not automatically post to your account. If you believe there may be a discrepancy, wait until ETS processes the scores, then contact customer service so they can manually connect the scores to your application.
Note that your application will not be delayed if you haven't yet taken the TOEFL. Your programs can view your scores once they are received. You should, however, be aware that some programs may need scores by a certain date; check with your programs to ensure you meet all deadline requirements.
