Students who are suspended or expelled from Massachusetts schools will soon have more educational options, under a new state law signed by Gov. Deval Patrick. Beginning in July 2014, school districts will have to provide expelled and suspended students with education opportunities, like alternative schools, tutoring or Internet learning modules. Each district will determine the options it will offer. Mitchell Chester, the state’s Elementary and Secondary Education commissioner, said there is currently no requirement to provide expelled or suspended students with these opportunities, with only a handful providing excluded students with alternative education programs. Chester said the department fully supports the new law, which Patrick signed Monday, as it helps to ensure a student’s ‘‘right to an education.’’ ‘‘We shouldn’t be washing our hands of school-aged youth by expelling them,’’ the commissioner said.
