Today we have made some amendments to the list of approved English language tests for applications made under tiers 1, 2 and 4 of the points-based system and for spouse or partner applications.
These amendments update the contact details for test providers and clarifies the acceptable test levels for tests provided by Trinity College. The required scores have not changed.
You can download the updated list from the right side of this page. When you make an application in an immigration category that requires you to demonstrate your English language ability, you must show that you have passed an appropriate test on the list.
