Skidmore says her daughter was forced to sit in the class for the remainder of test time, about 15 minutes, then mom was called after the test, and it was a 20-minute drive to school to pick up her daughter.
All the while, the little girl had to sit in the mess. No one bothered to clean her up, although a teacher did give her a trash bag to wrap around herself.
"You don't even treat a dog that way!" Skidmore said.
She says she's hoping policy will change, and common sense will prevail.
"I don't want this to happen to any other kid. That's the point of this: I don't want this ever happening."
School District Superintendent Bob Walker didn't want to go on camera, but said he wishes the school would've handled it differently.
"Bottom line, we regret what happened," Walker said.
He says, from here on out, he has instructed all his teachers to be more sensitive to other situations that might come up during testing like this one.
The little girl's dad has a tough time even talking about it.
"If any parent sent their kid to school with crappy pants, diarrhea-type crap, wrapped up in a garbage bag, stench badly, I believe with all my heart those parents would be facing criminal charges, I believe that with all my heart."
The family isn't pressing charges, but likely pressed hard enough for the school to consider changing its ways.
"If it's your child, I mean it hits a raw nerve, deep."
Many kids right now are taking Missouri Assessment Program (MAP) tests, the state standardized testing required by law. Those tests start in third grade, but the superintendent says the reason the teacher was sticking so closely to MAP testing guidelines, even for a kindergartner, is because she was trying to simulate the stringent rules to prepare students for what's to come.
