Analytical Resources: Trusted, Reliable, Respected

Improve Your Lab’s Accuracy

Laboratories around the world rely on the AACC Approved Methods of Analysis, 11th Edition, and Laboratory Proficiency Rating Program from Cereals & Grains Association (formerly AACC International) to ensure the accuracy and quality of their work. 


AACC Approved Methods of Analysis, 11th Edition

Cereals & Grains Association pioneered the development of standardized methods of analysis for cereal laboratories in 1915, and delivering analytical resources to the grain science community has remained a key cornerstone of our association

The 11th Edition of our Approved Methods of Analysis offers 350+ methods and enhancements, including built-in calculators, videos, spreadsheets, co-lab reports, and audio PowerPoints, in addition to color images that assist users in understanding or performing specific methods better or more quickly. 

Our analytical Methods are produced under the direction of the Approved Methods Technical Leadership Committee. Methods are developed and reviewed by technical committees for functionality and consistency before final approval. Requirements for the AACC Approved Methods of Analysis, 11th Edition, are consistent with those set by AOAC Intern​ational, AOCS, ISO, and the U.S. FDA’s Bacteriological Analytical Manual.


AACC Laboratory Proficiency Rating Program (LPRP)

Cereals & Grains Association introduced the Laboratory Proficiency Rating Program (previously Check Sample Service) in 1948 to solve for the fact that laboratories only had limited ways of ensuring accuracy. Today, laboratories around the world continue to rely on LPRP to accurately test equipment, monitor ​the use of proper methodology, qualify the work of contract laboratories, and ensure the accuracy of labeling information. 

Our Laboratory Proficiency Rating Program provides valuable quality measurement services including Proficiency Ratings and Laboratory Reference Samples.
