"Education is free," Godard, a member of the Action Now community group, said at a Board of Education meeting last month. "They're only in it for the money."
Opened three years ago and about to graduate its first senior class in the spring, Chicago Bulls College Prep is actually a member of the nonprofit Noble Network of Charter Schools, which operates a dozen schools serving 7,900 students across the city.
The Noble schools have said their disciplinary policies contribute to 90 percent of their students going on to college. Mayor Rahm Emanuel has praised the schools, saying they have the "secret sauce" to academic achievement.
"We do charge a fee when students get a detention," said Angela Montagna, spokeswoman for Noble. "It's a $5 fee, a disciplinary fee, and that goes to offset the cost of administering the discipline."
Godard said her son, Tavonta Gray, 16, had been suspended 15 times. Held back as a freshman last year, he was required to take a summer behavioral session in order to return this year — at a cost of $1,400. Godard estimated he has also rung up about $300 in fines this year along with additional ones last year.
"I'm trying to look for another school for next year," she said. "That school's not working for him."
And her son is not alone, she insisted. Dropping him off for detention one recent Friday, she estimated she saw hundreds of kids in line.
"Each child represents money," Godard said. "I was just floored when I saw that."
Noble charters have received steep funding increases from the Chicago Public Schools. According to the CPS 2013 budget, Chicago Bulls College Prep will receive $9 million next year, up more than 30 percent from $6.9 million this year. Montagna said that's based on a per-student formula and reflects higher enrollment.
