The school day will begin a little later beginning next year in ten Boston public high schools. Last night, the Boston School Committee approved a proposal from Superintendent Contompasis to shift start times in about half of the schools that now open at 7:20 a.m. The recommendation emerged as a result of studies by the district's REACT group (staffed by the Boston Plan for Excellence) and the Boston Student Advisory Council, who suggested that the early start times may contribute to student tardiness and absenteeism in the citywide high schools, a claim supported by national research. In order to accommodate the later start times, the School Committee modified the district's transportation policy, prioritizing routes to Boston Public Schools before scheduling trips to private, parochial and charter schools. While all students who live in Boston are still eligible for free BPS transportation, non-BPS schools may have to adjust their school hours in order to align with the district's bus schedules.
