“The charter movement is putting itself at risk by allowing too many second-rate and third-rate schools to exist,” Mr. Duncan says in prepared remarks that he is scheduled to deliver in Washington at the annual gathering of the National Alliance for Public Charter Schools.
In an interview, Mr. Duncan said he would use the address to praise innovations made by high-quality charter schools, urge charter leaders to become more active in weeding out bad apples in their movement and invite the leaders to help out in the administration’s broad effort to remake several thousand of the nation’s worst public schools.
