Hanna Skandera was appointed state commissioner in New Mexico three years ago by Republican Governor Susannah Martinez but has never been confirmed by Democratic legislators. She has never been a teacher, but has worked in policy positions for Governor Jeb Bush and Governor Arnold Schwarzenegger. (I knew her slightly when she worked at the conservative Hoover Institution as a research assistant.) Skandera is a member of Jeb Bush’s Chiefs for Change, a small group of state superintendents who support Bush’s policies.

Skandera is insistent on imposing a teacher evaluation plan that has no research evidence behind it. In fact, leading researchers like Stanford’s Edward Haertel oppose the model proposed by Skandera. Haertel, one of the nation’s most distinguished psychometricians recently spelled out the limitations of using test scores to evaluate teachers, such as proposed by Skandera. She wants test scores to count for 50% of teachers’ evaluations.

But Haertel says:

“…..there should be no fixed weight attached to the scores in reaching any consequential decisions. Princi- pals and teachers must have the latitude to set aside an individual’s score entirely — to ignore it completely — if they have specific information about the local context that could plausibly render that score invalid.”

Skandera seems determined to press for a formula that has worked mainly to demoralize teachers, not to improve education.
