In this paper the role of validity and reliability in the development of physical employment standards (PESs) and the consideration of these factors in determining the final pass/fail criteria for a PES and ultimately the legal defensibility of a PES is examined. Particular attention is paid to the use of subject-matter experts, the levels of evidence used in the establishment of the minimum acceptable pace/intensity for the completion of critical tasks, and the considerations needed in physical test selection.
