State education officials this week approved five new charter schools and expansion of 11 existing schools, extending an enrollment surge since the state passed a landmark education reform bill in 2010.
The move will create openings for some 3,100 new students, about half in Boston. The state education board granted charters to two new schools in Boston and approved expansion of seven.
Since 2010, when lawmakers doubled the number of charter school openings in struggling school systems, enrollment has climbed from around 28,000 to more than 33,000 in 77 schools.
Charter school supporters hailed the approvals, but said demand to attend the independently run schools is far outpacing growth.
