June 11, 2017, Concord (NH) Monitor: How taxes rise while enrollment drops in N.H. school districts like Merrimack Valley http://www.concordmonitor.com/MVSD-spending-and-taxes-over-time-9680179 …School administrators across the state also often point to growing special education needs. And in Merrimack Valley, the costs have skyrocketed. Minus state and federal reimbursements, the district spent $5.2 million on special education during the 2006-07 school year. Ten years later, it spent $10.3 million. MacLean said that, aside from a growing complexity and severity of needs, the biggest cost driver is paying for specialists, especially when a district can’t retain someone in-house.
