This is one of a series of guides designed to provide guidance for implementing activities that meet the requirements of a sound laboratory quality assurance program. The first of these, Guide C 1009, is an umbrella guide that provides general criteria for ensuring the quality of analytical laboratory data. Other guides provide expanded criteria in various areas affecting quality, producing a comprehensive set of criteria for controlling data quality. The approach to ensuring the quality of analytical measurements described in these guides is depicted in Fig. 1.

The training and qualification of analysts is one of the elements of laboratory quality assurance presented in Guide C 1009, which provides some general criteria regarding qualification. This guide expands on those criteria to provide more comprehensive guidance for qualifying analysts. As indicated in Guide C 1009, the qualification process can vary in approach; this guide provides one such approach.

This guide describes an approach to analyst qualification that is designed to be used in conjunction with a rigorous program for the qualification and control of the analytical measurement system. This requires an existing data base which defines the characteristics (precision and bias) of the system in routine use. The initial development of this data base is described in Guide C 1068. The process described here is intended only to qualify analysts when such a data base exists and the method is in control.

The qualification activities described in this guide assume that the analyst is already proficient in general laboratory operations. The training or other activities that developed this proficiency are not covered in this guide.

This guide describes a basic approach and principles for the qualification of laboratory analysts. Users are cautioned to ensure that the qualification program implemented meets the needs and requirements of their laboratory.
