Reacting to a drop in test scores this school year, angry parents decided that bullhorns were a necessity at an education panel last night. “Where is the accountability?," asked one parent whose son's scores had dropped. “Do your work for our children" said another. The ruckus was enough to make Schools Chancellor Joel Klein and the members Panel for Educational Policy walk out of their own meeting. DOE spokeswoman Natalie Ravitz told the Times, "Their shouting and screaming proved too disruptive for the panel to continue meeting, and rather than be heard, these individuals sabotaged their chance to speak and derailed important public business."
