UKVI has published revised updated listings of approved SELT centres with effect from 19th June 2020. These listings have been provided on the Home Office/UKVI web site as ODS (open document) spreadsheets rather than as .pdf documents.
This revised update follows hot on the heels of the previous update on 15th June...the 15th June version had failed to include the UKVI approved SELT centres operated in the UK and overseas by Pearson.
The new revised approved SELT centres inside the UK are here. Approved SELTS in the UK are offered by IELTS, LanguageCert, Trinity, AND Pearson.
UKVI advice is to confirm with SELT providers the status of their SELT test centres during the current COVID-19 circumstances.
The approved SELT centres outside the UK are here. There are now eight approved SELT centres in Thailand, all in Bangkok - rows 495 to 502. The UKVI approved SELTs are offered by IELTS (at 6 centres), LanguageCert (at 1 centre), and Pearson (at 1 centre) approved SELT tests.
The listing of UKVI approved SELTs with effect from 21st May 2020 remains in force.
