The Director of Human Resources Management shall be responsible for insuring that examination administration procedures, including, but not limited to, testing facilities, equipment, examination directions and instructions, and oral interview methods, are conducive to the equitable and reliable assessment of each promotional or recruitment applicant's abilities and aptitudes. Whenever the Director of Human Resources Management has reason to believe that standardized examination procedures would tend to cause an unreasonable impediment to, or an inaccurate measurement of, the ability or aptitude of a promotional or recruitment applicant who has a demonstrated disability, the Director of Human Resources Management shall, where feasible, provide a reasonable alternative or accommodation to such standardized procedures in order to provide for a more accurate measurement of any such applicant's ability or aptitude.
