Foreword
ISO (the International Organization for Standardization) and IEC (the International Electrotechnical
Commission) form the specialized system for worldwide standardization. National bodies that
are members of ISO or IEC participate in the development of International Standards through
technical committees established by the respective organization to deal with particular fields of
technical activity. ISO and IEC technical committees collaborate in fields of mutual interest. Other
international organizations, governmental and non-governmental, in liaison with ISO and IEC, also
take part in the work.
The procedures used to develop this document and those intended for its further maintenance are
described in the ISO/IEC Directives, Part 1. In particular, the different approval criteria needed for
the different types of document should be noted. This document was drafted in accordance with the

Introduction
Assessor competence results from experience and knowledge of the domain being assessed, possessing
skills in the application of the principle technologies of the ISO/IEC 330xx family of standards, and
personal attributes which contribute to effective performance. Competence is gained by a combination
of education, training, skills, and experience.
The lead assessor in an assessment team has the primary role of ensuring that the assessor team
members collectively have the right blend of specialized knowledge and assessment skills. The lead
assessor provides the necessary guidance to the team and helps to moderate the judgments and ratings
made by the members of the team to ensure consistency of interpretation.
A Body of Knowledge for the performance and application of process assessment is published as a
Standing Document by JTC 1/SC 7/WG 10 (Process Assessment) (N1180).
Figure 1 shows the key entities and relationships.
a) Assessors demonstrate their competence to perform assessments.
b) Competence results from:
1) the knowledge of the process;
2) skills in the principle technologies of ISO/IEC 330xx family of standards;
3) personal attributes which contribute to effective performance.
c) The knowledge, skills, and personal attributes are gained by a combination of education, training,
and experience.
d) An alternative to the demonstration of competence is to validate an assessor's education, training,
and experience.
