24 Pa. Stat. § 3-306
Whenever any school district is not coextensive with a city, borough, incorporated town, or township, the county commissioners shall furnish the proper election officials with a certified list of the qualified electors of such school district and with the necessary ballots to enable such electors to vote on matters pertaining solely to such school district. When such school district lies in two or more cities, boroughs, incorporated towns, or townships, or any combination thereof, the judge, inspectors, and clerks of each election district within such school district which lies in two or more cities, boroughs, incorporated towns, and townships, or any combination thereof, shall make out a complete return of all the votes given at any election for officers in the school district, or for the submission of any question to the electors of such district, designating the number of votes cast for each person, and for and against each question so submitted to the electors. Whereupon, the judge and inspectors shall appoint one of their number for return judge to meet the other return judge or judges of the school district, on the second day after any such election, at the oldest election place within the district or at such place within the district as shall have been appointed by the court of common pleas. The judges shall then and there add together the number of votes cast for each person voted for, and for and against any question submitted to the electors, and shall make out the returns as the nature of the election may require, complying in all respects with the provisions of existing election laws. After the performance of such duties, the return judges shall appoint one of their number, by consent or lot, to deliver, within two days thereafter, the full returns of the vote for officers, to the prothonotary of the court of common pleas, and of the vote on questions submitted to electors, to the clerk of the court of quarter sessions of the proper county, in the manner now provided by law for making township or borough returns. Such judges shall ascertain and declare the result of such election and shall issue certificates to persons elected to fill such offices, within five (5) days after making such returns.
