Proficiency Testing Provider
Secure and Confidential Website
AOAC’s proficiency testing website is secure and confidential. It allows participants to log on and submit responses, methodology, and results. Result reports are also issued electronically to the participants.
The secure AOAC proficiency testing website database stores all raw data submitted by participating laboratories and all result reports issued to them. If a laboratory ever needs to see what they have submitted, or needs additional copies of their reports, all they have to do is log into their AOAC proficiency testing account and they have immediate access to their submitted raw data and result report for all past and current testing rounds.
Participating laboratories can assign up to four additional reviewers for each round of testing. The reviewers can be anyone a laboratory would like to receive a copy of their results.
AOAC's PT reports offer a wealth of information that other programs do not provide. Each participating laboratory receives a report with information about their individual results and also information on all participating laboratories. Along with information on the test material preparation and summaries about the results, the quantitative reports also display the laboratory’s z-score results, standard uncertainty of the assign value, mean, SD, min/max, along with information on method performance. Plots include z-score plots and distribution plots.
