ECOT argued that it merely had to “present” 920 hours of “learning opportunities” for students, while the Ohio Department of Education said students had to be logged on and engaged in school activities. ECOT fought and lost multiple court challenges, and the state began “clawing back” $60 million that it paid the school in 2015-2016 based on the higher enrollment figure.
