Houston Superintendent Terry Grier wants the right to fire teachers based on students’ test scores, reports the Houston Chronicle. The school board will vote Thursday on the proposal.
HISD already uses a statistical analysis of student test scores to decide which teachers get performance bonuses. That same complex formula now would be used to highlight ineffective teachers.
The so-called value-added method measures whether a teacher’s students scored better or worse than expected on standardized tests. The formula, developed by North Carolina statistician William Sanders, projects how each child should score based on that child’s past performance.
Three or four years of data would be required to conclude that a teacher was ineffective, said Grier. Teachers would be given a chance to improve before being fired.
Currently, teachers can be fired for “a significant lack of student progress attributable to the educator.” But it’s not easy.
A Dallas teacher who was terminated for poor student achievement won back her job in 2008 after appealing to state Education Commissioner Robert Scott, who said her school’s environment was to blame.
Gayle Fallon, the teachers’ union president, argues the value-added method is too complex. In addition, value-added data is not available for all teachers.
Yesterday AFT President Randi Weingarten endorsed value-added analysis to judge teachers’ effectiveness.
