Abstract
Validating the examinations provided by conformity assessment bodies for personnel certification purposes is a requirement of the international standard ISO/IEC 17024 “Conformity assessment—General requirements for bodies operating certification of persons.” A fundamental requirement for each examination developer is to achieve a reliable and fair examination process. The validity of a test paper depends on the quality of the sections that constitute the examination. Considering that the examination must measure the competencies derived by the relevant job/task analysis, there is a direct connection between the job/task analysis outputs and the respective examination. There are prescribed steps in linking the relatedness of the examination to the knowledge and skills required for a job. These steps lead to an examination that has been “validated” in that its content accurately measures the necessary knowledge and skills required for the job. This paper describes the steps to design the ideal examination (personnel evaluation) system, as well as some of the statistical techniques that can be used to analyze items that are necessary to establish question banks. The scope of this paper is limited to the “job analysis” component of certification schemes and does not extend to requirements for administration of examinations, including performance-based assessments, oral examinations, and remote assessments.
