All units within this qualification are locally assessed via either an OCR set or centre devised practical assignment. All units are then externally moderated by OCR. It is the responsibility of the centre and candidate to ensure that work produced meets all of the evidence requirements as specified in the evidence checklist which accompanies the unit. For Level 1, copies of centre devised assignments should be included with the candidates work.

Prior to completing the assignment, candidates must have completed all tutorials and teaching sessions. There is no time limit for candidates to complete the assignment, however, between assessment sessions, work must be locked in a secure place.

The centre assessor is responsible for marking candidate's work in the centre. Large centres are likely to have more than one centre assessor, in which case they should take steps to ensure that the standard of assessment is consistent.

Centres are responsible for identifying staff that are able to act as centre assessors. OCR makes no specification regarding the background and experience of centre assessors other than they must mark the candidates' work in accordance with the unit specifications, the assignments and the assessment guidance.
