A special education teacher from the Bronx was found to have acted inappropriately by New York City Public School’s watchdog agency and was subsequently terminated last summer. Then, a few months later, she took a position at a nearby charter school that says the investigation into her wasn't flagged. The Bronx’s Atmosphere Academy says the teacher was fingerprinted and underwent a background check, raising questions about whether gaps that put student safety at risk exist between the nation’s largest school district and charter schools in New York City.
