Sažetak
Selection a trainee on a panel uses the ISO-methodology, which may include usage of the sequential tests. Sequential tests are a means to economize the number of evaluations (as much as 50%) required to draw a conclusion, for example, acceptance vs. rejection of a trainee on a panel. Tests are very practical and efficient as they take into consideration the possibility that the evidence derived from the first few evaluations may be quite sufficient to draw a conclusion. Evaluations are conducted according to the procedure appropriate for the chosen method and the results of each completed test are entered into a graph in which three regions are identified: the acceptance region, the rejection region and the continue testing region. Testing continues until a point touches or crosses one of the lines bordering the region of indecision. This work showed how in the simply way, with minimum number of the evaluations, may be reached a decision of acceptance or rejection of a trainee on a panel.
