Proficiency testing requirements

Requirements for proficiency testing providers

We strive to make the lab-accreditation review process efficient, accurate, and timely. To do so, we require that proficiency testing providers send us the electronic data-deliverable files, as well as the PDF file for each proficiency testing study report.

In order to be recognized by the Lab Accreditation Unit, proficiency-testing providers must:

• Comply with the most current TNI Proficiency Testing standard.
• Assure electronic data deliverable (EDD) and PDF files are submitted electronically to us within one month after the close of a proficiency testing study.
• Comply with Washington state's EDD formatting requirements based on the criteria and file structures commonly used for comma delimited text files:
  • data.txt
  • summary.txt
  • final.txt
