Candidates must demonstrate his or her competency through doing everyday trading standards work. As this work is real, conditions are not consistent and each candidate will have been assessed on their merits and their performance in the context with all of its variables.
It is the job of the assessor to examine the evidence of the work and make a judgement as to whether or not the candidate meets the required minimum level of competency in his or her performance.
This judgement is always going to have a large subjective element. However, each candidate who achieves an award must have had to achieve the same minimum level of performance. The standardisation process is in place to minimise this subjectivity.
assessor ensures that he or she adheres to the assessment criteria
assessors discuss assessment criteria to help remove any ambiguity and to ensure all assessors are requiring the same level of performance
assessors within a locale or regional group form networks to discuss assessment strategies and interpretation of portfolio criteria
assessors discuss interpretation with internal and external verifiers
internal verifiers examine the work of a number of assessors, thus ensuring assessors are not requiring too much or too little of a candidate
external verifiers (EVs) also have a level of standardisation. EVs sample the work of the internal verifier and ensure all assessment decisions and process have been fairly and consistently applied
the lead verifier's role is to ensure consistent practice over the whole process
