Washington, D.C., has rejected a charter school's request to expand its enrollment. The Washington Post says the city's Public Charter School Board raised concerns about the number of students who have left BASIS DC since it opened last year. The school opened as a campus for grades 5 to 8; it plans to gradually become a school for grades 5 to 12. BASIS DC is part of a chain of charter campuses known for rigorous academic demands; some district officials have questioned whether the school's focus was a good fit for Washington. The school wanted to raise its enrollment cap to bring in more money to pay rent on its facility.
