State Sen. Sonia Chang-Díaz has been receiving an education in persistence the last few years as she has continually fought for legislation that would reform education fund across the state. On Wednesday, she led a press conference to once again announce a bill to reform education funding. Last session the House and Senate passed their own education reform bills, but couldn't agree on a funding reform package before the legislative session ended. So that led to legislators, municipalities, teachers, students and education advocates, coming together on Wednesday to promote the passage of the Education Promise Act. The bill would reform the state's education funding formula and better serve students across Massachusetts.
