Nevada was confident enough in the partial student results from its Common Core-aligned state test that it released them Wednesday, even though 7 of 10 students weren't tested because of computer glitches.

But Montana says it won't decide what to do with its test results until it can be sure the scores are valid.

The varying actions are part of the ongoing fallout from the meltdown last spring of the federally mandated annual testing process that is linked to funding.

And it isn't the first time states have had to deal with compromised test results from a standardized system that is supposed to allow for easy comparison across years and states.

Neither Kansas nor Wyoming released statewide numbers when they had incomplete data previously.
