Teachers Are Put to the Test More States Tie Tenure, Bonuses to New Formulas for Measuring Test Scores

Stephanie Banchero & David Kesmodel:

Teacher evaluations for years were based on brief classroom observations by the principal. But now, prodded by President Barack Obama's $4.35 billion Race to the Top program, at least 26 states have agreed to judge teachers based, in part, on results from their students' performance on standardized tests.

So with millions of teachers back in the classroom, many are finding their careers increasingly hinge on obscure formulas like the one that fills a whiteboard in an economist's office here.

The metric created by Value-Added Research Center, a nonprofit housed at the University of Wisconsin's education department, is a new kind of report card that attempts to gauge how much of students' growth on tests is attributable to the teacher.

For the first time this year, teachers in Rhode Island and Florida will see their evaluations linked to the complex metric. Louisiana and New Jersey will pilot the formulas this year and roll them out next school year. At least a dozen other states and school districts will spend the year finalizing their teacher-rating formulas.

"We have to deliver quality and speed, because [schools] need the data now," said Rob Meyer, the bowtie-wearing economist who runs the Value-Added Research Center, known as VARC, and calls his statistical model a "well-crafted recipe."

Much more on value added assessment, here.
