An NVQ is a National Vocational Qualification. It is a work-based qualification designed to measure competence in a professional role.
It is is different from a traditional taught course as it requires you to show what you currently do and how you have the underpinning knowledge required to do your job, as opposed to teaching and testing you on new knowledge. To prove your competence, you as a candidate are required to collect evidence from your workplace in line with the National Occupational Standards (NOS) of the NVQ.
By completing an NVQ it shows your current and potential future employers that you are competent in your role and demonstrates an interest in continuous professional development, improving your employability.
