What would happen if legal challenges forced districts (and district-hired attorneys) to certify that the numbers derived from statistical models are an accurate reflection of an individual educator's practice? That's what they're doing with home foreclosures now, putting attorneys on the line (NPR). Attorneys are officers of the court, and judges don't like to be lied to. Hat tip to Eduwonk for a link to a discusion of why "a flood of lawsuits is certain to occur" when test scores are used in evaluations. Unions
