how that their English is of a high enough standard to successfully engage with and complete their course at SOAS?

This query contains a significant institutional mismatch. SOAS University of London is a distinct higher education provider with its own separate English language entry requirements, typically requiring IELTS 6.0 or equivalent for undergraduate study. The Level 5 Diploma in Health and Social Care Management Online (RQF, 120 Credits) is an OTHM accredited, Ofqual regulated qualification delivered by independent learning providers, not SOAS. There is no direct administrative link between the OTHM Level 5 Diploma and SOAS admissions. If you are seeking to progress to a Level 6 Top-Up Degree or a Foundation Degree, you must check the specific English language requirements of the university offering that progression route, as these vary by institution and are not governed by the OTHM qualification itself.
