Voters will fill two of the board's five seats.
Ms. Hilton was active on the Menlo Park-Atherton Education Foundation before her successful 2008 run for the board. She has served as board president.
Mr. Child, who also was active in the foundation, served a four-year term beginning in 2006, but chose not to run for re-election in 2010. When a board member resigned in mid-2011, however, he applied for the vacant seat and was appointed by a unanimous vote of the board.
District residents have until Friday, Aug. 10, to file candidacy papers for a board seat. If Mr. Child changes his mind and doesn't run, the deadline will be extended to Aug. 15.
There are also two spots on the Las Lomitas school board on the November ballot. As of the Almanac's Monday press time, no one had taken out papers to run.
