Charter school enrollment in the District, which made up a scant 5 percent of the total public school population in 1998, has broken the 40 percent mark, according to preliminary figures released Monday.
The unaudited data, based on an Oct. 5 count, show charter enrollment at 32,009, an 8.2 percent boost over last fall’s 29,557. Traditional public school enrollment, which ticked up last fall for the first time in four decades, dipped slightly to 46,191, down less than 1 percent (419 students) from last October.
