Another charter school in Broward County, Fla., has closed, this time for failing to pay its rent. The South Florida Sun-Sentinel reports that College Bound Academy of Excellence in Margate, Fla., is the third charter to close this month in the county. The school board accepted the voluntary termination of the school, which had about 60 students in grades 6 to 12. The school's landlord notified the district last week that the charter company had turned in its keys.
