The NBCE has been in the business of producing fair, valid and reliable exams since 1963.
According to NBCE Director of Practical Testing Paul Townsend, D.
is a member of the NBCE Board of Directors who chaired the Part IV Committee during the development of Part IV.
Therefore, before the NBCE could produce Part IV, it had to determine what conditions a practitioner would likely encounter in practice.
The NBCE has since released two updated reports, in 2000 and 2005.
