There is no cost. It is free to send your test results to institutions.
When sending your results, you can select up to 40 institutions. If you select fewer than 40 institutions, you can add more later.
If you need to send your results to more than 40 institutions, you may contact support. Please note we will ask you to confirm that you are officially applying to all the institutions you request us to send your results to. Just sending your Duolingo English Test result to an institution is not enough to be considered for admission by an institution. You must also officially apply to the institution.
