Universities do not accept scanned PDFs of your result. They need an "Official Electronic Score Report" sent directly from IDP. Here is how to do it.
Test Report Form (TRF) is the official name for your score card. When a university asks for your IELTS, they are asking you to "Send your TRF" through the portal.
You can send scores to 5 universities for free if you select them at the time of booking your test (or within 24 hours of booking).
The scores are sent automatically once released. If you don't achieve your target score, the university will still receive it.
If you have already received your results and now want to apply to universities, follow these steps on the IDP website:
Log in to the IDP IELTS Candidate Portal.
Go to dashboard and click "Apply for Additional TRF".
Search for the University/College name in the dropdown.
Pay the fee (approx ₹250-₹400 for Electronic Mode).
Not sure which delivery method your university accepts?
