The practice of industrial hygiene: Role Delineation Analysis American Board of Industrial Hygiene

To better assure that the content of the American Board of Industrial Hygiene's Core and Comprehensive Practice Examinations are reflective of the current practice of the profession, the Board conducted a validation of their test specifications. The validation effort involved development of Domains of Practice, i.e. Recognition, Evaluation, Control, and for Comprehensive Practice, Management. Within each domain, Task Statements and the associated knowledge and skills necessary to successfully complete the task were identified. This overall "role delineation" was submitted to a random sample of 200 Certified Industrial Hygienists who were asked to identify the relative importance of each Domain and each Task and identify the percent of time and industrial hygienist might devote to each. An excellent response rate of 68.5% was achieved and provided ABIH with sets of weights for each Domain and Task Statement. These weights will be used by the ABIH to update future versions of the two examinations with initial influence in 1986 followed by a greater impact in 1987.
