The school board, which has seen voters reject two school bond issues, has decided to try again in November.
The board decided Tuesday night to place a $53-million bond issue on the Nov. 3 ballot.
Voters in 1993 and 1994 narrowly rejected $29.1-million bond issues to build a new high school.
San Gabriel teenagers attended high school in Alhambra until 1994, when Gabrielino High School opened at the site of a former elementary school.
Since then, district officials have sought funds to improve facilities.
