We started the process of achieving accreditation due to our own evaluations resulting in many differing opinions on whether certain requirements were being met or not. Working with A2LA has resulted in no longer spending resources on correcting issues that were the result of differing opinions; A2LA has assessed our laboratory numerous times with three different assessors and they all have had the same interpretation of the requirements. This allows my lab to focus on improvements rather than correcting issues. A2LA is extremely cost efficient; they provide professional, knowledgable assessors, and make the entire process from initial contact to assessments extremely simple. If you work through the process of accreditation, you will come out the other end with a much better calibration program that will stand up to intense scrutiny.
