Thompson: Expectations Mismatch Between Models & Rhetoric

Look below the surface and you'll see an interesting disconnect between value-added teacher rating models and reform rhetoric.  The value-added models used by the Los Angeles Times and described elsewhere are explicitly in acknowledging the correlation between income and student achievement. But district leaders are pushing them deny that those "expected results" should be expected.  They are of the "no excuses" school of opinion, but their value-added models aren't.  JT(@drjohnthompson)Image via.
