Can a person who previously had an open acs case become a foster parent?

The answer is complicated. I would say on average its 15%yes and 85% No. That is if the prior ACS case the person had was "Indicated" AKA Guilty AKA credible evidence was found by Child Protective Specialist that the allegation made in the report more likely than not occured. If the prior case was "Unfounded" AKA Not Guilty AKA no credible evidence was found by CPS then the prior case would not even matter when applying to become a foster parent. Although relatively few, there are some people whom have "Indicated" cases who become foster parent. However, this is usually in cases of kinship foster paent where the foster parent is genetically related or is considered family by the biological family of the foster child. And even in those few cases where this occurs, the certiifying foster care ageny must put in safety interventions in order to reduce risk of any potential harm to the child. ACS will also monitor your home closely and close your foster home if you have any "slip ups", which ultimately removes all foster children whom you were caring for at the time.
