Getting enough students into the classroom has become a problem for three Delaware charter schools.
State officials say that Freire Charter School, Delaware Lab Design Lab High School and Prestige Academy have been placed on formal review.
Freire and Design Lab are brand new.
Prestige has been around for just over a half a dozen years.
The state required charter schools to reach at lead 80 percent enrollment by the first of this month.
This affects the amount of funding they will receive from the state of Delaware.
