The essential purpose of proficiency testing is to give participants reassurance on the quality of their performance and enable them to identify any trends or errors of consequential magnitude-those likely to affect decisions-in their reported results and then eliminate the causes of those errors. We must recognise, however, that all results of measurements include error. It's only a question of whether the errors are of acceptable size-in effect, whether results are fit for purpose. Fitness for purpose emerges therefore as the key feature of proficiency testing.
能力验证的根本目的是让参与者对其表现质量放心，并使他们能够识别其报告结果中任何具有重大影响的趋势或错误——那些可能影响决策的错误——然后消除这些错误的原因。然而，我们必须认识到，所有测量结果都包含误差。这只是一个误差大小是否可接受的问题——实际上，就是结果是否符合目的的问题。因此，符合目的成为能力验证的关键特征。
