As Monday evening, Youngblood had 12,142 votes, while Cruz has received 12,262 votes, according to the San Bernardino County Registar of Voters.
Voters had to choose three Chino Valley Unified candidates during the Nov. 6 General Elections.
Top vote-getter and incumbent James Na has 20,364 votes and newcomer to the board Irene Hernandez-Blair is in second place with 14,769.
"So far (Cruz) is in third place, but we can't say they're winners until we certify the results. Although those numbers are there, they're not certified yet and it's not accurate to say they're winners yet," said Felisa Cardona, spokeswoman for the county Registrar of Voters on Tuesday.
"We estimate we will be certifying the elections by the end of the week."
As of last night the Registar of Voters had 300 provisional ballots to count for the entire San Bernardino County, which is a mix of all the precincts, Cardona said.
Since 2004, Youngblood has been elected twice to the Chino Valley Unified board.
According to Cruz's biography he's a teacher/librarian and has never run or held an elected seat.
