If your scores can no longer be released to Yale by ETS, please take the test again.
The test should be taken as early as possible to ensure that your scores are received in time to be incorporated in your file.
Normally ETS will not release TOEFL scores that are older than two years.
If you took the TOEFL before and ETS will release those scores, then you should not have to retake the examination.
You may substitute the IELTS for the TOEFL
For additional information and the latest updates on the TOEFL please visit the ETS website.
