Generally apprentices move on to a different partnership for each segment. During apprenticeship, the proficiency of apprentices is appraised by blinap through the same recordings and measurements that are used to appraise partners. Apprenticeship proficiency is also appraised by the partners with whom the apprentice is working. Further, at the end of each apprenticeship year, the apprentice takes the qualtests again. When appraisals from the three sources differ, an investigation is triggered to determine why.
Apprenticeship ends when the apprentice's appraised proficiency reaches practitioner quality.
Measures of proficiency are thus direct measures of practice. In any kind of practice that does not involve the possibility of physical damage or harm, we dispense with indirect measures of qualification altogether, and depend entirely on appraisals of proficiency to qualify. The purpose of indirect qualtests is to accurately predict what the level of proficiency will be when the individual commences actual practice. The gamble costs nothing up front.
