24 Pa. Stat. § 3-308
At the first municipal election occurring more than thirty (30) days subsequent to the formation of such new school district, a board of school directors for such district shall be elected or appointed, as provided in this act. Such school directors shall be elected or appointed for such terms that the number and terms of those whose places are to be filled at each succeeding municipal election shall be the same as the number and terms of those whose places are filled at the corresponding election in other school districts of the same class.
When two or more school districts are combined into a single district as the result of State Board approval, the directors then in office in each component school district shall, until the end of their respective terms, be directors of the newly formed school district. Vacancies occurring in such incumbent positions shall not be filled. At the first municipal election following the date of establishment of the new district and at each subsequent municipal election, three directors shall be elected at large for six year terms. Their term of office shall begin on the first Monday of December following their election.
The school directors of the component districts of the new district before the date of establishment or the board of school directors after establishment, may, if they choose, develop a plan to divide the new school district into three or nine regions in the same manner as provided in section 303 of this act.
