It’s difficult to make accurate projections about future charter enrollments and costs.  How fast will existing schools expand?  How soon will new ones get started?  How much would charters cost under various funding projections?

I have done projections based on the best figures I could put together.  And now the New Hampshire Department of Education has released its own calculations.  The NHDOE projections are similar to mine but their figures suggest that, where I projected that HB 435 could cost the State $25 million more over the next three years, NHDOE thinks the figure could be closer to $30 million.

In both cases, these are predictions so it is important to read the assumptions in the footnotes, but the message is the same: charter school funding has been growing fast in New Hampshire and HB 435 will further accelerate that growth.
