The first day of school for Region 12 students has been delayed even before the year was scheduled to begin.  The Bridgewater, Roxbury and Washington district was slated to hold classes tomorrow, but schools will now open after Labor Day, on September 3rd.  Region 12 was getting ready to open the new Agriscience Academy at Shepaug Valley High School but construction material took longer to get to the site than planned.  The material has since arrived and is still being installed.  The addition will be completely finished by the end of the calendar year.
