The Atlanta school board on Monday will consider allowing a public charter school operator to add two new schools and grow enrollment by 1,100 students.  KIPP Metro Atlanta Collaborative Inc., which runs a handful of charter schools through a contract with Atlanta Public Schools, wants to increase its enrollment cap from 3,100 students to 4,200 students and open a new kindergarten through fourth grade primary school and a new fifth through eighth grade academy, according to school board documents. The enrollment zone would include the entire city of Atlanta, with “preferential weight given to economically disadvantaged students,” the document outlining the proposal states. KIPP also seeks to lease the former Walter White Elementary School on Detroit Avenue from the school district to operate KIPP Soul Academy. The Atlanta Board of Education is scheduled to discuss and consider action on the proposal at its 6 p.m. Monday meeting.  KIPP submitted a waitlist of more than 2,875 students interested in its schools, according to APS. If approved, KIPP Soul Primary School would open next school year, with KIPP Soul Academy opening in 2019 or 2020, according to KIPP spokeswoman Callie Hudak, who said all but one of its eight existing metro Atlanta schools are within the Atlanta school district.  Check back for more on this developing story.
