As a means to improve the quality and consistency of environmental data throughout the United States and to foster the mutual recognition of laboratory accreditation by Accreditation Bodies, the mission of the Laboratory Accreditation Body Committee is to develop and support accreditation standards by engaging experts in a consensus-based standards development process. 

Strategic Goals and Objectives:

  • Periodically review the TNI Standards for laboratory accreditation bodies (Volume 2, Modules 1 & 3) and recommend revisions as necessary for consistency and improvement.
  • Support the NELAP Accreditation Council (AC) and the Laboratory Accreditation Systems Executive Committee (LASEC) in preparing draft policies and procedures to support program implementation, as requested by LASEC.
  • Support the TNI Standards for accreditation bodies by developing and recommending appropriate training and guidance materials as coordinated within the TNI to facilitate the implementation and adoption of these standards on a national level.
  • Review and respond to Standards Interpretation Requests, as referred.
  • Gather and disseminate information on accreditation body activity as requested.  This may include surveys and interviews.
  • Monitor and report on ISO Conformity Assessment Committee (CASCO) Work Group revisions to ISO/IEC 17011.Support NELAP by completing any tasks assigned by the Board or required by the AC.

 Success Measures:

  • Successful adoption of policies, standards and recommendations by TNI and NELAP.
    • Acceptance and use of database for laboratory applications and a generic TNI application to make the process easier.
    • Acceptance of adopted policies and procedures to support NELAP
  • Continued mutual recognition among Accreditation Bodies.
  • Decisions that are found acceptable by federal, state and private sector organizations.
  • Increased number of NELAP accreditation bodies and/or accreditation bodies adopting the use of TNI Standards.
  • Increased number of organizations recognizing NELAP accredited laboratories.

Key Milestones for 2015:

Review of Volume 2, Modules 1 & 3, TNI Environmental Laboratory Sector Standard

  • November 2015 – Complete review and finalize recommendation about the need to revise and whether to combine the two modules into one. 
  • December 2015 -- Initiate development of implementation plan for the revision.

 For the generic application form:

  • Date TBD – Present beta version of the generic application for review and comments.  Identify beta testers. (depends on timing of completion of development)
  • Date TBD – Make the above mentioned tool available for use; provide information and/or training to the laboratory and AB community.


  • Volunteer member organization with significant time constraints.
  • Maturing TNI infrastructure can provide the required resources for the committee to achieve its goals.
  • TNI Webmaster has adequate time to complete generic application development.
  • The committee has the ability to identify and engage the right expertise to get their job done. 
  • The committee has the ability to implement an effective consensus-based standards development process
  • ABs and other stakeholders will accept the work products of the committee.
  • Budgetary and financial constraints, as well as industry politics, may prevent the adoption of otherwise usable solutions.
  • Standards must establish a consistent baseline for achieving good data quality but provide for maximum flexibility with minimum prescriptiveness.

 Available Resources:

  • Volunteer committee members
  • Existing national and international consensus-based standards
  • EPA Cooperative Agreement
  • TNI Website
  • Other TNI Committees (Expert and Administrative/Support functions)
  • Participating organizations
  • A potentially large group of volunteer associate members to help with committee objectives.
