English language tests for private hire drivers

Secure English Language Tests (SELTs) assess English Language ability and are taken under specific secure conditions.

Trinity's ISE I (B1) SELT is accepted by Transport for London (TfL) for private hire driver applications where evidence of English language ability is required.

Trinity’s ISE I SELT is a B1 four skills test that meets the TfL requirement.
