The board of education shall administer a grant program known as the parent-school participation program. The purpose of the program shall be to increase parents' participation in their children's schooling statewide and especially in the 24 school districts and five charter schools that the department of education has identified as having the lowest levels of student performance on the Massachusetts comprehensive assessment system exam. Elementary schools shall offer parental preparation class prior to a child's kindergarten registration. Funding appropriated for this program shall be used to: support increased numbers of teacher-parent conferences, hold open houses, encourage teachers to use technology to communicate with parents, and other forms of school-parent outreach. Said funding may be used to expand the roles of existing school and district personnel, and may not be used to hire additional school or district personnel. Grant recipients shall be required to demonstrate improvement in parental involvement as a result of the grant. Any funds distributed under this grant program to local, or regional school districts shall be deposited with the treasurer of the city, town or regional school district and held in a separate account and shall be expended by the school committee without further appropriation, notwithstanding any general or special law to the contrary.
