Interlaboratory Comparisons (ILC) and Proficiency Testing (PT) programs involve much more than simply distributing samples and collecting results. The true expertise lies in accurately evaluating hundreds of different data points from participating laboratories using internationally recognized statistical rules. Prepared by our expert instructors and consultants, this training covers the latest version of the ISO 13528 standard. Throughout the course, you will learn critical computational methods step-by-step: from assessing the "Homogeneity and Stability" of proficiency test items, establishing assigned values, and applying robust statistics, to calculating performance indicators like the "z-score" that evaluate participant competency. Whether you are a specialist in a reference laboratory, a PT provider organization, or a quality department, join this training to elevate your statistical evaluation skills to international accreditation standards.
