Science supports the later start times, but school districts’ budgets often do not, reports Providence Journal.

“This is a health issue,” said Cumberland Supt. Robert Mitchell. “You can’t say this isn’t the right thing to do. The evidence is overwhelming.”

But Mitchell, like many other school leaders, worries about the price tag. He estimates it would cost more than $500,000 to switch to a later start time in Cumberland — something his district can ill-afford.
