Dale Chu, who came to Florida from Indiana with Tony Bennett, has resigned his position as chief of staff at the Florida Department of Education.
Chu resigned Friday, said Joe Follick, spokesman for the education department.
In a brief resignation letter, Chu provided no reason for his departure. His resignation is effective Sept. 3, his letter said, and he would be on "annual leave" until then.
Bennett resigned from his post as education commissioner on Thursday, amid a controversy over the Indiana Department of Education's decision to change the grade of a charter school founded by a man who'd donated to Bennett's campaign. Bennett had been Indidana's top education official, which is an elected post, before he was tapped for the job in Florida in December.
The story about Indiana changing that charter school's A-to-F grade -- first reported by the Associated Press -- was based on a series of emails between Bennett and his staff.
Chu was copied on many a number of emails and in a few appeared to be discussing how changes to the formula might impact the school's grade. "The only way we get to an A is by dropping the 3.51 cutoff to 3.5," he wrote on a Sept. 14 email to Bennett and others.
Though he defended his actions in Indiana, saying they were done to fix a flawed grading system, Bennett said he resigned because the story had become a "distraction." He called the reports from Indiana "malicious and unfounded."
Several staff members who worked with Bennett in Indiana came to Florida after he was hired here and took jobs in Tallahassee at the state's education department.
For example, Will Krebs, now a deputy commissioner in the accountability division, was director of policy and research in Indiana's department.
Krebs was also among the group Bennett emailed last year about that state's grading formula and the Christel House Academy charter school's grade.
Follick said there have been no other leadership changes since those made last week. Those changes included the State Board of Education appointing Pam Stewart as interim commissioner, a post she'd held previously while also serving as chancellor for K-12 education.
