Sorry to say this - but the Armed Forces have their own interpretation of what is equivalent. Also, this from the learndirect website:
Are the certificates in Adult English and maths equal to GCSEs?
The English and maths certificates (Level 1 & 2) are equivalent in level to GCSEs, but not in breadth.
The certificates were devised as an alternative to GCSEs for adults, and it has always been the intention that the certificates should be accepted by Higher Education Institutions (HEI) as an equivalent qualification.
It is important to be aware that as these institutions are independent and there are still a number of them who do not accept the certificates. learndirect have no control over this, therefore all learners who need a qualification for entry onto a specific course e.g PGCE, should confirm with their individual HEI institution whether they will accept the certificates before enrolling.
So - a few places don't see them as equal either, including some universities. I guess you either get a Level 3 or a GCSE.
