5 CFR § 302.202 - Qualification requirements.
Before making an appointment to a position covered by this part, each agency shall establish qualification standards such as those relating to experience and training, citizenship, minimum age, physical condition, etc., which shall relate to the duties to be performed. An agency may delegate the establishment of standards relating to a group of positions or a specific position to the appropriate administrative level or subdivision in accordance with the needs of the locality in which the position is located, but the agency shall determine that each standard established is in conformity with this part. Each agency shall make its standards a matter of record in the appropriate office of the agency, and shall furnish information concerning the standards for a position to an applicant on his/her request. Each agency shall apply the standards for a position uniformly to all applicants, except for such waivers as are provided in this part for a preference eligible. An agency shall not include a minimum educational requirement in qualification standards, except for a scientific, technical, or professional position the duties of which the agency decides cannot be performed by a person who does not have a prescribed minimum education. An agency shall not establish a maximum age requirement for any position. Each agency shall make a part of its records the reasons for its decision under this section and shall furnish those reasons to an applicant on his/her request. The qualification standards shall include:
(a) A provision for waiver by the agency of requirements as to age, height, and weight for each preference eligible when the requirements are not essential to the performance of the duties of the position; and
(b) A provision for waiver by the agency of physical requirements for each preference eligible when the agency, after giving due consideration to the recommendation of an accredited physician, finds that the applicant is physically able to discharge the duties of the position.
