How to find aschool that closed down in 1980 in Chicago,Il in the Loop trying to get transcript.

If the information is available at all. It would be at the Dept of Education for the State of Ill.

Many private schools just close, records are hauled away, some just left in the schools and thrown out when someone takes the buiding over.

But if the school, was accredited they would have sent records to the state.
