All school districts having a population of not fewer than 1,000 and not more than 500,000 inhabitants, as ascertained by any special or general census, and not governed by special Acts, shall be governed by a board of education consisting of 7 members, serving without compensation except as herein provided. Each member shall be elected for a term of 4 years for the initial members of the board of education of a combined school district to which that subsection applies. If 5 members are elected in 1983 pursuant to the extension of terms provided by law for transition to the consolidated election schedule under the general election law, 2 of those members shall be elected to serve terms of 2 years and 3 shall be elected to serve terms of 4 years; their successors shall serve for a 4 year term. When the voters of a district have voted to elect members of the board of education for 6 year terms, as provided in Section 9-5, the terms of office of members of the board of education of that district expire when their successors assume office but not later than 7 days after such election. If at the regular school election held in the first odd-numbered year after the determination to elect members for 6 year terms 2 members are elected, they shall serve for a 6 year term; and of the members elected at the next regular school election 3 shall serve for a term of 6 years and 2 shall serve a term of 2 years. Thereafter members elected in such districts shall be elected to a 6 year term. If at the regular school election held in the first odd-numbered year after the determination to elect members for 6 year terms 3 members are elected, they shall serve for a 6 year term; and of the members elected at the next regular school election 2 shall serve for a term of 2 years and 2 shall serve for a term of 6 years. Thereafter members elected in such districts shall be elected to a 6 year term. If at the regular school election held in the first odd-numbered year after the determination to elect members for 6 year terms 4 members are elected, 3 shall serve for a term of 6 years and one shall serve for a term of 2 years; and of the members elected at the next regular school election 2 shall serve for terms of 6 years and 2 shall serve for terms of 2 years. Thereafter members elected in such districts shall be elected to a 6 year term. If at the regular school election held in the first odd-numbered year after the determination to elect members for a 6 year term 5 members are elected, 3 shall serve for a term of 6 years and 2 shall serve for a term of 2 years; and of the members elected at the next regular school election 2 shall serve for terms of 6 years and 2 shall serve for terms of 2 years. Thereafter members elected in such districts shall be elected to a 6 year term. An election for board members shall not be held in school districts which by consolidation, annexation or otherwise shall cease to exist as a school district within 6 months after the election date, and the term of all board members which would otherwise terminate shall be continued until such district shall cease to exist. Each member, on the date of his or her election, shall be a citizen of the United States of the age of 18 years or over, shall be a resident of the State and the territory of the district for at least one year immediately preceding his or her election, shall be a registered voter as provided in the general election law, shall not be a school trustee, must not have been removed from a school board pursuant to Section 2-3.25f-5 of this Code (unless subsequently appointed as a member of an Independent Authority or if it has been 10 years since the abolition of the Independent Authority in the district), and shall not be a child sex offender as defined in Section 11-9.3 of the Criminal Code of 2012. When the board of education is the successor of the school directors, all rights of property, and all rights regarding causes of action existing or vested in such directors, shall vest in it as fully as they were vested in the school directors. Terms of members are subject to Section 2A-54 of the Election Code.
Nomination papers filed under this Section are not valid unless the candidate named therein files with the county clerk or the county board of election commissioners, as the case may be, of the county in which the principal office of the school district is located a receipt from the county clerk showing that the candidate has filed a statement of economic interests as required by the Illinois Governmental Ethics Act. Such receipt shall be so filed either previously during the calendar year in which his nomination papers were filed or within the period for the filing of nomination papers in accordance with the general election law.
Whenever a vacancy occurs, the remaining members shall notify the regional superintendent of that vacancy within 5 days after its occurrence and shall proceed to fill the vacancy until the next regular school election, at which election a successor shall be elected to serve the remainder of the unexpired term. However, if the vacancy occurs with less than 868 days remaining in the term, or if the vacancy occurs less than 88 days before the next regularly scheduled election for this office then the person so appointed shall serve the remainder of the unexpired term, and no election to fill the vacancy shall be held. Should they fail so to act, within 60 days after the vacancy occurs, the regional superintendent of schools under whose supervision and control the district is operating, as defined in Section 3-14.2 of this Act, shall within 30 days after the remaining members have failed to fill the vacancy, fill the vacancy as provided for herein. Upon the regional superintendent's failure to fill the vacancy, the vacancy shall be filled at the next regularly scheduled election. Whether elected or appointed by the remaining members or regional superintendent, the successor shall be an inhabitant of the particular area from which his or her predecessor was elected if the residential requirements contained in Section 10-10.5 or 12-2 of this Code apply.
A board of education may appoint a student to the board to serve in an advisory capacity. The student member shall serve for a term as determined by the board. The board may not grant the student member any voting privileges, but shall consider the student member as an advisor. The student member may not participate in or attend any executive session of the board.
