Paul Soglin:

In parting, let me share with you the findings of a Northwestern University professor, James Rosenbaum.* He studied poorly performing high school students, virtually all Black, from the Chicago Public Schools who moved into areas served by suburban schools. His findings were that most of these failing students in Chicago were getting C’s in the suburbs. A tougher school district and improved grades!
The main point of his paper was to challenge the commonly accepted conclusion that once a student was doing poorly academically, there was not much hope for turn around after the 6th or 7th grade. His findings completely contradicted that conclusion.
