ASTM E2159-01

In a situation where an organization is performing an evaluation of another, either formally or informally, the single most important element in the evaluation may well be the selection and assignment of a properly qualified assessor/assessment team to perform an on-site assessment. Therefore it is imperative that the person(s) performing the assessment be selected and assigned with care by the assessing organization. Two basic types of individuals normally participate in an on-site assessment: assessors/auditors and technical experts; each perform separate functions (see definitions).

This document focuses on providing guidance regarding the responsibilities and obligations of an assessing body in the selection, training, assignment and monitoring of assessors/auditors and technical experts to carry out their evaluation functions.

Note 1—In some cases, others may also participate in an assessment who are beyond the control of the assessing body: e.g., government regulatory personnel, or other observers specified by a client. Such participants are not covered by this document.

1.1 This document provides guidance to organizations that need to utilize persons to perform assessments/audits (assessing bodies) of other organizations (assessed bodies) for purposes of recognition, accreditation or other type of approval to perform a function.

1.2 An assessing body should consider the contents of this document and apply it according to its unique situation. The elements of this document should be applicable to the selection, assignment, and monitoring of assessors whether they are contract or permanent staff members.
