New Jersey Statutes Title 18A. Education 18A § 8-29

The membership of the board shall, except as otherwise provided by this chapter, be apportioned by the county superintendent or county superintendents among the several consolidating school districts as nearly as may be according to the number of their inhabitants, as shown by the last published federal census report, but each district shall have at least one member. The apportionment of membership shall continue until changed by reapportionment by the county superintendent or county superintendents, which shall be made, when required, immediately succeeding each published federal census report, but the members of the board in office at the time of any reapportionment shall continue in office for their unexpired terms.
