TIA Recap
The PT Committee issued 6 TIA for public comment earlier this summer.
5 TIA were made to bring consistency between V1M2 and V2M2
1 TIA was issued for V3 to correct an error that was overlooked during standards development

Background and Recap History
Hold for Next Revision Comments
LASC White Paper – Newport Beach
Request from Advocacy Committee
![Page 6: PT Program Kirstin McCracken, TNI PT Committee Chair Quality Assurance Manager TestAmerica, Burlington Laboratory.](https://reader036.fdocuments.in/reader036/viewer/2022070307/551b78e6550346167e8b4628/html5/thumbnails/6.jpg)
Rationale for Change
Costs of PT 2X per Year exceeds benefits to lab performance
TNI PT Frequency is primary barrier to expansion of national accreditation
TNI PT Frequency is out of line with Federal Program Requirements, specifically, USEPA Drinking Water Program
There is no real difference between WP & WS PT matrices; methodology and technology are equivalent.

PT Frequency Subcommittee
NJ Data Study- published on TNI website AB Survey Lab Survey All State Data Study PT Frequency Subcommittee Report
Report Completed August 3, 20098 Conclusions , 1 Recommendation
![Page 9: PT Program Kirstin McCracken, TNI PT Committee Chair Quality Assurance Manager TestAmerica, Burlington Laboratory.](https://reader036.fdocuments.in/reader036/viewer/2022070307/551b78e6550346167e8b4628/html5/thumbnails/9.jpg)
Subcommittee Conclusions
Labs that take more PT may have better performance – but cannot isolate frequency from other factors such as quality system
Data reviewed did not support any proposed theory for difference in laboratory performance and PT
PT Frequency is not the sole barrier for attracting more AB Authoritative Association of Scientists (IUPAC) recommend 2 PT per year Other Federal Agencies (DOE, DoD) require 2 PT per year External publications show more frequent PT equals better lab
performance Economic impact of a reduction in PT frequency is difficult to determine
with available information. International efforts for PT frequency is based on individual laboratories
Based on current information available, there is no compelling reason to support a change to the current PT Frequency requirement in the TNI Standard

PT Committee Vote
Hold for Next Revision Comments under consideration:
Reduce Frequency from 2 to 1 PT per Year Combine WP & WS into 1 Study
Is the rationale for change substantiated by the data studies and surveys conducted by the subcommittee; the White Papers and other reference information reviewed by the committee; and by the public debate that has occurred in support of or against a change?

PT Committee Vote
Decision Type: High Stakes / Confidential
Decision Making Rule:Enthusiastic Support (80% Affirmative)
For a comment to be found persuasive; 7 out of 9 committee members must vote affirmatively.

Negative Vote Rationale The rationale that reduction in PT Frequency
would attract more participating ABs and Labs is speculative and cannot be substantiated with current information available.
Rationale to combine WP & WS into a single aqueous PT with the most stringent concentration range and acceptance criteria would create unnecessary burden on many laboratories; methodology between WP & WS is not equivalent for all parameters.

Next Steps
Post PT Frequency Subcommittee report on TNI Website along with survey and data studies.
Committee to review vote comments, prepare formal response to comments found not persuasive.

Conclusion
TNI is a consensus based standard; by consensus the TNI membership must establish the purpose of PT and then determine the best PT scheme to achieve that purpose.
We need to hear from you-all of you.
