My Wife worked for this after school program/daycare and it cinched the decision we will never put our kids in daycare if humanly possible.
She worked there all of a couple months and gave notice after a time of evaluation they went through there. Everything they did, every practice and policy, was hidden for this week long process where inspectors come in and observe. She was trained one way but told to do everything the opposite for the duration of this. Then everything went back right after it was over.
While I don't recall a specific instance of blatent harm, we were really sickened by the disregard for cleanliness and supervision state standards. Then to hide their true practices for the once a year certification, was just sad.
