That's the question a legislative panel is investigating. Lawmakers are scheduled to hear from several local elected officials and school leaders on Friday.
Their concern is the impact of the state formula for funding public schools, and the way it calculates tuition for charter schools.
Cumberland Town Councilor Arthur Lambi, a Republican, is among those planning to testify. According to Lambi, Cumberland sends about $3 million to charter schools every year, and that number is expected to grow as charter schools add more seats.
