Tier 2 applicants must demonstrate their acceptable standard of English.
30 October 2008. Tier 2, relating to skilled workers, replaces the current work permit scheme. Tier 2 of the points-based system (PBS) will open in the United Kingdom (UK) on 27 November 2008. This will enable UK employers to recruit individuals from outside the European Economic Area (EEA) to fill a particular job that cannot be filled by a British or EEA national.
One of the requirements of the PBS will be that, in most cases, migrants coming here to undertake skilled or highly skilled work must provide evidence to demonstrate that they have an acceptable standard of English. The ability to speak English to a competent level improves a migrant’s potential to succeed in the labour market and to integrate in the United Kingdom.
One way in which applicants can demonstrate this will be by providing evidence that they have passed an English language test. Only tests that have been assessed as meeting the UK Border Agency standards will be accepted as evidence that the applicant meets this requirement.
Here is a list of tests accepted by UKBA: Points Based System English Test, Global Test of English Communication, Test in English for International Students, International ESOL Diploma, Certificate in English Language, English for Business Level 4, Test of English as a Foreign Language (TOEFL), Test of Englsih for International Comparison (TOEIC), International English Language Testing System (IELTS), Business English Certificate (BEC).
