A-level language equivalent is at least B2, if not C1, depending how you operationalise it. Many native speakers won’t pass a C1 level in their own language as those tests do not reflect everyday conversations at work or socially. For example, I likely won’t past C1 in my native Romanian, especially after living in the UK for a long time. Similarly, many of my British friends don’t have A level English. If we want to support integration, what is needed is investment in ESOL locally, especially on vocational ESOL in the workplace. Because there is limited or no use to knowing all types of conditional sentences if you don’t know the vocabulary needed in your trade or job.
