Personally I don`t think the background checks are as necessary as some would have you believe. I can see it for someone that wants to work in daycare but has no kids of their own and is just starting out because there is little information to base a decision on. But if a caregiver had done anything that would be picked up in the background check - against a child the reality is the CAS would have stepped in and taken the caregivers own children into safe custody and the caregiver wouldn`t be able to give many years worth of references from satisfied customers.
I understand why organizations have the requirement and it is mainly to protect themselves legally down the road should anything happen.
A background check is also something not everyone can get because it requires photo ID so for anyone that doesn`t have a drivers license, passport or immigration card with a photo they are out of luck. Also the backlog in some areas especially spring as students are looking for jobs and fall when they need to do vollunteer work can be a couple months. Again there may better ways to get the information. As a caregiver I have had over the years a couple parents that I later found out information about that might have been picked up in a background check. Sometimes I think as caregivers it would be more important to get checks done on the parents that are going to come to our house - as in adults on the premises when we are there alone with the kids than it is for parents to require background checks of caregivers.
