More than 160 students — nearly 30 percent of the student body — at D.C.’s celebrated Duke Ellington School of the Arts live outside the city and are not paying the tuition required of suburbanites who attend the District’s public schools, an internal investigation has found. The findings, which city officials announced Friday, come amid intensifying distrust of the District’s public schools, stoked by scandals involving inflated graduation rates and a former chancellor skirting enrolment rules for his daughter.

Ohio Auditor’s opponent in the state attorney general’s race said that he should immediately have referred to authorities a whistleblower’s allegations that the state’s then-largest online charter school intentionally inflated attendance figures. The Education Department previously found that the school significantly over-reported its number of full-time-equivalent students and owed the state $60 million for the 2015-2016 school year. Another $19 million penalty was assessed for 2016-2017.
