The TOLC is valid for at least the year in which it is taken.

Let's take an example!
A TOLC taken in March 2025 will be valid until December 2025.

Some universities may extend the TOLC validity. For instance: a TOLC result obtained in 2024 may also be valid in 2025.

Find this information on the admission notice;or on the regulations of the degree course on the university's website.
