On-Site Assessment (OSAT)

NVQ Diploma Levels 2 and 3

On-site assessment enables candidates with work experience to gain an NVQ Diploma Level 2 or 3. Our assessors visit you on-site to measure your work against the required elements of the NVQ Diploma programme. The assessors’ observation notes, combined with written and photographic evidence from the candidates, make up the candidate portfolio to complete the NVQ Diploma.
