The Vermont House has given final approval to a bill that would shake up the way schools in the state are governed, consolidating the number of school districts from more than 270 to around 50. President Obama has recently announced a plan to develop ratings for teacher preparation programs. A report released last year gave Vermont a poor grade for its efforts to train teachers. And the focus from the White House has renewed controversy about ranking institutions where future teachers are educated. Nonprofit organizations that help Vermonters find insurance on the new health exchange are giving mixed reviews to the program.
