How Much Should a Teacher's Job Depend onTest Scores?
The school system dismissed seventy-five teachers last year. It was the first year of a new teacher rating system.
Experts say such large numbers of dismissals are rare in American schools. But in Washington the rating system is not governed by the labor contract with the teachers union. So school officialshave more freedom.
The system is called IMPACT. Teachers are observed in the classroom five times a year for at least thirty minutes eachtime. They are also judged by student test scores.
Administrators rated sixty-five of the twohundred six teachers as "ineffective." The others lost their jobs because they were rated "minimally effective" for a second year.
The National Council on Teacher Quality is a research group that works to increase the number of effective teachers. EmilyCohen, a policy director there, says the council supports the IMPACT system.
EMILY COHEN: "This is an evaluation instrument that is finally able to capture who is highly effective and who is ineffective and who could be doing better and could use some assistance. Mostevaluation instruments in the country do not capture teacher performance -- allteachers are rated satisfactory."
Some Washington teachers say their ratingsdepend too heavily on test scores. For some teachers, half of their rating isbased on how well their students do. But Emily Cohen says test scores areimportant.
EMILY COHEN: "Testing is probably one of the -- it's the most objective data that we have on teacher performance. The District also is looking at other things, using master educators to evaluate teachers. So it's not just looking at student test performance, it is using other sources of data."
Teachers with the highest rating --"highly effective" -- can receive a performance bonus of up totwenty-five thousand dollars. In addition, they can receive a pay increase.
Almost sixty percent of the teachers who were rated "minimally effective" last year stayed in the schoolsystem and improved. School officials say these teachers received help to become better.
Michelle Rhee created the IMPACT system.She gained national attention for her aggressive reform efforts when she ledthe troubled school system in the nation's capital. She left last year and herdeputy, Kaya Henderson, took her place.
The Washington Teachers Union says IMPACTunfairly hurts teachers who work in schools with high rates of poverty. The Washington Post reported that most of the teachers with the highest rating work in schools with lower poverty rates.
