53 Pa. Stat. § 23442
The civil service commission, in each city of the second class, shall require persons applying for admission to any examination provided for under this act or under the rules and regulations of the said commission, to file in its office, a reasonable time prior to the proposed examination, a formal application, in which the applicant shall state under oath or affirmation:--
First.--His full name, residence, and postoffice address.
Second.--His citizenship, age, and place and date of his birth.
Third.--His health, and his physical capacity for public service.
Fourth.--His business and employments and residences for at least the three previous years.
Fifth.--Such other information as may reasonably be required, touching the applicant's qualifications and fitness for the public service.
Blank forms for such applications shall be furnished by the said commission, without charge, to all persons requesting the same. The said commission may require, in connection with such application, such certificates of citizens, physicians or others, having knowledge of the applicant, as the good of the service may require. The said commission may refuse to examine an applicant, or, after examination, to certify an eligible, who is found to lack any of the established preliminary requirements for the examination or position or employment for which he applies; or who is physically so disabled as to be rendered unfit for the performance of the duties of the position to which he seeks appointment; or who is addicted to the habitual use of intoxicating liquors or drugs; or who has been guilty of any crime or of infamous or notoriously disgraceful conduct; or who has been dismissed from the public service for delinquency or misconduct; or who has made a false statement of any material fact, or practiced or attempted to practice any deception or fraud in his application, in his examination, or in securing his eligibility; or who refuse to comply with the rules and regulations of the commission. If any applicant feels himself aggrieved by the action of the commission in refusing to examine him, or, after an examination, to certify him as an eligible, as provided in this section, the commission shall, at the request of such applicant, appoint a time and place for a public hearing; at which time such applicant may appear, by himself or counsel, or both, and the commission shall then review its refusal to make such examination or certification, and testimony shall be taken. The commission shall subpoena, at the expense of the applicant, any competent witnesses requested by him. After such review, the commission shall file the testimony taken, in its records, and shall again make a decision, which shall be final. When any position to be filled involves fiduciary responsibility, the appointing officer may require the appointee to furnish a bond, or other security, and shall notify the commission of the amount and other details thereof: Provided, however, That any surety company, the bonds of which are accepted by a judge of any court of record of the county wherein the city is located, shall be a sufficient surety on any such bond.
