Only days into the new school year, the Detroit Delta Preparatory Academy for Social Justice announced that it was closing, stunning students and parents. Enrollment was lower than expected, and the school was not financially viable, according to its authorizer, Ferris State University.

The decision left many of the high school’s students in tears.

“Everybody was breaking down,” said Ajah Jenkins, 17, a senior at the school, which had just begun its fifth year of operation.

Ajah called her mother, Kelye King, “crying, hysterical, screaming, saying, ‘My school’s closing. How am I going to graduate,’ ” King recounted.

Saturday is supposed to be the school’s homecoming. It’s unclear whether it’ll still happen, said King, who is upset because she believes the school should have given parents a heads-up that this might happen.

“I’m just disappointed. I entrusted her education to a group of people — they’re making me feel like I failed her, like I didn’t do enough research.”

The other day, we learned that a charter school in Delaware was closing with no prior notice.

That’s the market for you. Stores open and close without warning.

Schools are not supposed to be like that. They are supposed to be a public service that is always there for the students.

Maybe the market for schools is saturated. After all, you can’t expect to open a shoe store on every corner and expect them all to thrive or survive.
