When you participate in our Standardization and EQA programs, you advance the Oneworld Accuracy Collaboration, the largest and most successful EQA collaboration in the world. 
Collaboration Members harmonize programs to the highest international standards using common samples, challenge formats and test event calendar and manage their respective programs on OASYS (Oneworld Accuracy System), a shared informatics system developed and hosted by the Collaboration Secretariat, the Oneworld Accuracy Group based in Vancouver, Canada. OASYS is widely regarded as the most sophisticated and flexible informatics system of its kind anywhere.
