The D.C. Inspector General is satisfied that there was no systemwide cheating. The office investigated Noyes campus and found that maybe there was a teacher or two who might have cheated.

The U.S. Department of Education seconded the nearly clean bill of health offered up by the DC IG.

But here are the actual scores of the Noyes school, compiled by retired DC teacher Erich Martel and posted on G.F. Brandenburg’s blog. Those retired DC teachers are plenty smart.

Look at those scores: First they soar up, then they plummet down.

Nothing suspicious there, right?

And apparently that is not the only school in D.C. where scores rose and fall in ways that suggest systematic tampering.

This is a scandal that will not die. There is too much evidence left on the table.
