It is proposed that a single rating be given for each element cognisant of the levels demonstrated in each activity or sub element but not tied by formula or a reductionist approach to the rating of each sub element. The rating is to be given using an on balance approach.
For example, in a niche area such as vapour sampling. Would lack of vapour sampling skills result in applicant being deemed inadequate?
Applying this to the specific question regarding a lack of vapour sampling skills, the competency assessment would take into account the competency of an applicant in sampling methodology and design across all media, in conjunction with all the other sub elements of competency element 3. The outcome would be a balanced consideration of all the sub elements, so a lack of vapour sampling skills on its own would not prevent assessment at “proficient”.
