Some Vermont students may soon have less time to laze in the summer sun. Consistent with national trends, public schools in Chittenden, Grand Isle and Franklin counties are considering a school calendar reorganization plan. The new schedule would have shorter summer vacations but extended midyear breaks, called "intersessions." According to Chittenden South Supervisory Union superintendent Elaine Pinckney, the goal is to more evenly distribute students' learning while minimizing "summer boredom" and the educational slippage that occurs when kids are away from class for too long. But don't cancel your vacation plans yet — assuming parents approve the switch, it won't be adopted before the 2014-15 school year.
