The AOCS Laboratory Proficiency Program (LPP), formerly the Smalley Check Sample Program, is the world's most extensive and respected collaborative proficiency testing program for oil- and fat-related commodities, oilseeds, oilseed meals, and edible fats. More than 500 chemists participate to verify their lab’s quality control.

Participants use  AOCS or similar methods for sample analysis and then compare their results with a large cross-section of other laboratories using the same methods and samples.

• Participating in LPP may be sufficient for national and professional accreditation requirements.
