Research Institute logo

The Performance Tested MethodsSM (PTM) program helps companies and their customers safeguard their businesses, mitigate risk, and protect consumers through trusted, reliable testing methods and products. Search Performance Tested Methods >

The PTM program provides independent third-party review and certification for proprietary test method performance. The certification mark assures users that an independent assessment found that test method performance meets an appropriate standard for its intended use. 

The PTM program process is: 

  1. The method developer and an AOAC RI technical consultant prepare a validation outline for validation study protocols in the consulting phase. 
  2. AOAC staff reviews the application.
  3. The method developer completes its validation study.
  4. AOAC RI selects an independent lab to complete the independent validation study.
  5. AOAC RI facilitates expert peer review of the results of both validation studies. If approved, AOAC RI grants AOAC Performance TestedSM certification, and the organization is licensed to use the certification mark.
  6. The certification is reviewed for renewal the following year.
