Do you have any pointers to data showing this close? Most of what I've seen shows the gap being shockingly persistent in the face of intervention across a wide variety of systems, but I'm always looking for more.

I reccomend Malcolm Gladwell's podcast on the subject. He makes a strong argument that the failure to integrate teachers to any degree caused a large part of the failure. Some of his sources are on the page, but I haven't reviewed them well personally.
