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 TNI Laboratory Accreditation Body Committee is to develop and support accreditation standards by engaging industry experts in a consensus-based standards development process.

  • Using ISO standards as a model this committee will develop and maintain a module to address the programmatic requirements for accreditation bodies.
  • As needed, support these accreditation standards with appropriate training, guidance and other materials to facilitate implementation and adoption of these standards on a national level.
  • Further refine the consensus-based accreditation standards that are consistent with other national and international standards and cost effective, avoiding unnecessary duplication and non-value added requirements.
  • Continually evaluate and establish success measures to target opportunities for improvement.
  • Establish and maintain an environment for standards development that will ensure continual improvement of accreditation standards that are aligned with the regulatory and industry specific requirements.
  • Utilize existing and future TNI infrastructure and resources to accomplish mission.
