National vocational qualifications (NVQs) are work-related, competence-based qualifications.Usually nurses take the NVQ health and social care which is related to their finished course, also medical courses like PT can take that course in UK if they want to study there. This is what I know.
If you are interested to study in UK and take NVQ, make sure to ask the school so they can assess you and your finished course if it is relevant to your qualification.
