LYNNFIELD – The Lynnfield School Committee approved a concussion policy for the school district Tuesday night in compliance with a state mandate that districts statewide pass such a policy by March 1.?What you have before you is pretty much a boilerplate policy,” Superintendent Thomas Jefferson said to the committee before its vote.Jefferson also told the committee that the schools? coaches have already been mindful of concussions in the various sports.?It?s not anything we haven?t been doing,” he said of the policy.In an interview after the meeting, Jefferson said the policy outlines the education that students and coaches need to have about concussions and the protocol following a concussion occurrence.Committee member Timothy Doyle said during the sub-committee reports portion of the meeting that the high school expansion project will be going out to bid next week. Doyle is a part of the school building sub-committee.?Hopefully we?ll have a shovel in the ground before the end of the school year,” he said.Jefferson then said that the target completion date for the construction is December.At the end of the meeting, the School Committee approved a reduced budget for fiscal year 2013 that has a 4.5 percent increase from last fiscal year, as opposed to the former 4.9 percent increase proposal. A 4.5 percent increase would put the school district?s operating budget for fiscal year 2013 at $19,467,090.The School Committee will meet again at the Lynnfield High School Media Center on March 13.Sarah Mupo can be reached at [email protected].
