Good Scores, Good Teacher

December 28, 2010

While debate rages in the education world about how to measure effective
teaching - or whether it is even possible to do so - research funded by
a prominent advocate of data-driven analysis has found that growth in
annual student test scores is a reliable sign of a good teacher. The
Bill & Melinda Gates Foundation reported that and other preliminary
findings Friday from a $45 million study of teacher effectiveness in
several cities. "In every grade and subject we studied, a teacher's past
success in raising student achievement on state tests was one of the
strongest predictors of his or her ability to do it again," said Vicki
Phillips, who oversees elementary and secondary education grants for the
foundation.
