Despite a last-ditch effort to save the Alternative Center for Education, the board's vice president said she believes the school will close.
"Barring something unforeseen, I'm expecting it will be coming to an end," said Angela Petersen, who also serves on the Upper St. Clair School Board.
The alternative school on the Parkway West Career and Technology Center campus is at risk to close due to high costs and low student enrollment.
"Unfortunately it really comes down to cost," Petersen said. "The enrollment does not support the cost of the school. Cost has gotten way out of hand.
"It's very sad."
The closing will affect one Upper St. Clair student, according to Superintendent Patrick O'Toole, and about 40 students from 11 other school districts.
The vote is scheduled for the next board meeting in January.
About 50 supporters of the school made pleas to the board to keep it open at the last board meeting in November.
