While the scope of the term physical employment standards is wide, the principal focus of this paper is on standards related to physiological evaluation of readiness for work. Common applications of such employment standards for work are in public safety and emergency response occupations (e.g., police, firefighting, military), and there is an ever-present need to maximize the scientific quality of this research. Historically, most of these occupations are male-dominated, which leads to potential sex bias during physical demands analysis and determining performance thresholds. It is often assumed that older workers advance to positions with lower physical demand. However, this is not always true, which raises concerns about the long-term maintenance of physiological readiness. Traditionally, little attention has been paid to the inevitable margin of uncertainty that exists around cut-scores. Establishing confidence intervals around the cut-score can reduce for this uncertainty. It may also be necessary to consider the effects of practise and biological variability on test scores. Most tests of readiness for work are conducted under near perfect conditions, while many emergency responses take place under far more demanding and unpredictable conditions. The potential impact of protective clothing, respiratory protection, load carriage, environmental conditions, nutrition, fatigue, sensory deprivation, and stress should also be considered when evaluating readiness for work. In this paper, we seek to establish uniformity in terminology in this field, identify key areas of concern, provide recommendations to improve both scientific and professional practice, and identify priorities for future research.Key words: employment standards, human rights, standard setting, cut-scores, reliability, validity.Résumé : La portée de l'expression normes physiques relatives à l'emploi étant vaste, cet article met l'accent sur les normes associées à l'évaluation physiologique de l'aptitude au travail. On utilise généralement ces normes d'emploi dans le domaine de la sécurité publique et des interventions d'urgence (p. ex. policier, pompier, militaire); ceci étant, il est toujours possible d'améliorer la qualité scientifique de ce domaine de recherche. Historiquement, la majorité de ces emplois sont occupés par des hommes, ce qui pourrait inclure un biais lié au sexe lors de l'analyse des exigences physiques et de la fixation des seuils de performance. Il semble acquis que les travailleurs plus âgés occupent au fil du temps des postes moins exigeants physiquement. Toutefois, comme ce n'est pas toujours le cas, le maintien à long terme des aptitudes au travail pourrait s'avérer problématique. Depuis longtemps, on porte peu d'attention à la marge d'incertitude concernant les seuils de coupure. L'établissement d'un intervalle de confiance au seuil de coupure pourrait combler cette incertitude. On devrait possiblement prendre en compte les effets de la pratique et de la variabilité biologique sur les résultats des tests. La plu...
