So last year all the governors got together and agreed on a uniform way to measure their dropout rates.
But now, two states have taken a novel (or, I guess, not so novel) approach to the new requirements -- they've dropped out.
Yes, North and South Dakota have abandoned their plans to use the unified formula. And three other states -- Hawaii, Washington and Illinois -- haven't yet decided whether they're going to stick to the plan.
That would leave the governors with a 10 percent dropout rate. Not as bad as the estimated national average, but not great either.
