The Los Angeles Times last week did what few, if any, school districts are willing to do -- analyze teacher performance over multiple years with the intent of making the results of that analysis available to teachers and parents, alike. Teacher union representatives have been quick to condemn the newspaper's plans to post this information online in a searchable database. But U.S. Education Secretary Arne Duncan and no few teachers in the Los Angeles Unified School District saw merit in the project, as do we.
Public education can benefit from more transparency. The disclosure of data on student achievement and teacher effectiveness can be a good thing -- for teachers, parents and American education.
"Too often our systems keep all of our teachers in the dark about the quality of their own work," Duncan told an audience in Little Rock, Ark. "In other fields, we talk about success constantly, with statistics and other measures to prove it. Why, in education, are we scared to talk about what success looks like?"
It seems a great many teachers have no such fear. Duncan noted that more than 2,000 Los Angeles teachers had called the Times last week to ask for their scores.
The concern has always been that achievement tests are not a reliable or complete measure of teacher eectiveness. It's a valid concern. Certainly, test scores are not a complete measure, and should never be used as such in decisions on hiring, firing or career advancement. Whether or not test scores can be a reliable, or fair, measure depends on how thorough and careful the analysis.
