24 Pa. Stat. § 4-436
Every person elected treasurer of any school district, including the city treasurer elected as treasurer of a school district of the first class, shall, before entering upon the duties of his office, furnish to the school district a proper bond, in such amount and with such corporate surety as the board of school directors therein may approve, conditioned for the faithful performance of his duties as school treasurer. If any school treasurer is re-elected, he shall furnish a new bond for each year. The treasurer's bond may be paid for by the school district. In lieu of furnishing such a bond, the treasurer may file his own collateral bond, in such amount as may be required by the board of school directors, secured by an actual deposit with the board of school directors, or with any bank or trust company within the Commonwealth which may be agreed upon, of any of the securities which depositories may use to secure the deposit of school funds as herein provided. The total market value of the securities, thus deposited, shall equal the amount of the collateral bond. Such collateral bond shall be conditioned upon the faithful performance of his duties as treasurer. The securities, thus deposited, shall constitute a trust fund to be available for the satisfaction of any liability accruing upon the collateral bond. The securities shall be accompanied by a proper assignment or power of attorney for their transfer. Such trust deposit, in the event of any depreciation in its value, shall be maintained, upon request in writing of the board of school directors, at the amount provided therein. The board of school directors may permit the treasurer to substitute for any one or more bonds or obligations included in any such securities, other bonds or obligations that meet the requirements of this act.
The school treasurer shall not enter upon the duties of his office until his bond, with the proper corporate surety or securities, has been furnished to, and approved by the board of school directors.
