The Newtown Board of Education has signed off on school start time changes.  High Schoolers, who this year had to be in class by 7:20am, will start their day at 8am in the fall.  The Newtown High School day will end at 2:30pm.  Changes are also being made to the middle and intermediate schools.  Elementary times are not changing.  The Board of Ed says the move is budget neutral.  Officials are hoping for improved physical and mental health and improved academic performance.  They also cited safety improvements with students not waiting in the dark at bus stops.
