• Description:
  This report examines the rating criteria used in the Environmental Lead Proficiency Analytical Testing (ELPAT) Program. ELPAT employs simple criteria based on the number of acceptable results to rate a laboratory's performance. In this study, the statistical power of the current criteria was calculated and compared with alternative criteria based on z-scores. The results indicated that the alternative criteria are more powerful in detecting poor laboratory performance and more flexible in detecting bias or poor precision. The alternative criteria can be easily adjusted for various needs and the estimates of bias and precision of each participant can be obtained using the z-scores. [Description provided by NIOSH]
